Asset management  MARGINAL COSTS COMPUTATION, ECONOMETRIC APPROACH

The marginal costs computation relating to railway infrastructures is fundamental for a fair and sustainable redistribution of costs among all the players operating in the rail sector. The various regulations over the years have opened the European railway transport market to competition, orienting the principles of imposing the charges for the use of the infrastructure according to fair and non-discriminatory criteria.
In this study, based on the works in the literature, a relationship was identified between the costs borne by the infrastructure manager and traffic data according to an econometric approach. This method estimates the costs directly linked to the provision of the railway service, identifying the corresponding marginal costs. All the proposed models try to interpret the dependence of costs on the load according to various mathematical models.
The elasticity and marginal costs resulting from the models, applied to the case study of the Italian railway network, seem to be in line with the results obtained in the other studies, falling within the same order of magnitude. However, a real comparison cannot be made without considering the context in which these costs were calculated. A national railway network changes from one state to another in relation to many factors. The most obvious are the geomorphology of the area, the climatic conditions, the characteristics of the vehicles (weight, speed and length) and the evolution of technologies. Furthermore, the different distribution of the most important cities in the area, and therefore of the demand for mobility, deeply changes the structure of the network. As a result, the main cost items that make up the operator’s financial statements will differ from one country to another. The needs of the infrastructural system, specific to each country, will change the management of economic resources linked not only to maintenance, but also to the improvement of the network itself.

4481 23 July 2022 at 10:53 am David Taylor Private Participation in the African Union’s Agenda 2063: leveraging regional efficiencies Project architecture (Public ownership, PPP, Franchises, etc.)  Third Party Access, Interoperability

In light of African Union’s Agenda 2063, African States are increasingly seeking out Standard Gauge Rail technology for regional rail megaprojects, with high speed, high capacity rail connectivity at the core of this ambition. A most recent announcement was the inclusion of Standard Gauge Rail in South Africa’s recently announced National Rail Policy.

With a view on the AfCFTA, African Union’s Agenda 2063 and a regional policy environment that is more inclusive of the Private Sector, how can Regional Governments leverage Private Sector involvement in current and upcoming rail projects to create more value for the upstream economies and bolster rail in Africa’s transport modal mix.

Furthermore, once greater regional connectivity is achieved through expansive SGR rail builds, how do we approach topics such as interoperability and cross-acceptance?

4493 4 August 2022 at 10:05 pm Inara Watson Factors Affecting the Energy Consumption of the Selected High-Speed Railway Systems Energy measurement and efficiency  Energy measurement, Efficiency

The world economy experiences essential changes, including the increasing globalization of the economy, which may significantly impact the transport system and the environment.
High-speed railways (HSRs) are the most sustainable way to transport passengers and goods as they operate on an electrified network. Because an HSR system is an energy-intensive transport system, it is important economically and environmentally to reduce the amount of used energy.
In this research, the non-radial Data Envelopment Analyses methodology has been used to estimate the dynamic changes in the total energy consumption for seven HSR systems over 2010-2017 and benchmark the most energy efficient HSR systems. The results of IBM SPSS indicate a strong negative correlation between the energy efficiency scores and to weight/seat ratio and a strong positive correlation between energy efficiency scores and seat utilization ratio.
The research findings have shown that changes in energy consumption strongly correlate with the type of high-speed rolling stock and operational strategies. This research will support train operators to make decisions when acquiring new trains and assess the benefits of acceleration in the modernisation of the current rolling stock. The expected outcomes of this research will contribute to the development and advances of more sustainable HSR systems.

4497 9 August 2022 at 8:42 am Miroslav Haltuf High Speed Rail as a complex mobility and innovation driver Wider socio-economical impacts  High Speed Rail, Mobility

High-speed rail is becoming an integral part of the railway system. Building it where it does not yet exist, for example in Central and Eastern Europe, is not easy. I am not referring to the design and construction itself, which is manageable almost anywhere in the current conditions. In my presentation, I would like to reflect on the socio-economic impact on society and on the territory. There are many questions, but the most important ones that I would like to seek answers to in my presentation are as follows:
– How will or can high-speed rail transport (HSR) affect the mobility of people and goods in the area?
– How does the demographic structure of the population affect the development and use of HSR?
– is it better to change the mobility of citizens and the industrial development of a territory or is it more efficient to change the routing of HSR and the configuration of the rail network?
– Will new HSR lines significantly affect the capacity of existing conventional lines in favor of rail freight transport?
– What is the impact of transport cost on the decision to choose a transport mode?
– How to integrate HSR into urban mobility and ITS concepts?
Finally, I would like to mention the possibilities of low-emission high-speed rail transport. Is it rather a vision that has no hope of being realized in the near future, or is it a path heading in the right direction? There are many questions, but there are not so many satisfactory answers.

4498 10 August 2022 at 1:04 pm Paige Malott Benefits of Building High Speed Rail at Airports Connections with urban, regional networks and airports  economic, climate

In North America, the Cascadia megaregion has reached a tipping point where expanding its mobility choices to include high speed rail is critical to plan for long-term growth and address large-scale challenges such as climate change.

The Cascadia megaregion, which includes Seattle and Portland in the U.S. and Vancouver, Canada, is reported to grow by 3.6 million people by 2050; three times the size of the current population. Regional growth plans only account for 2.3 million of those people, leaving a gap of 1.3 million people unaccounted for where they will live and work, as well as adding further demand on the region’s strained transportation network. Additionally, a study on regional growth in aviation found that Seattle’s Sea-Tac airport will exhaust all expansions by 2027 and still be over capacity by 3 million passengers annually. Decision-makers are exploring building two additional airports to meet demand. Meanwhile, 60 percent of the region’s carbon emissions come from passenger transportation. Legislators have set a goal to reduce carbon emissions by 80 percent by 2050 in alignment with the Paris Climate Accord. On our current trajectory, Cascadia will miss this goal and only decrease emissions by 20-30 percent without a game-changing investment in fast, high-capacity, clean-energy transportation, such as high speed rail.

This study examines the economic, mobility, and climate benefits of building high speed rail at airports, and recommends how collaboration between aviation and high speed rail can improve outcomes for megaregions compared to each mode operating in a silo.

4509 30 August 2022 at 1:35 pm Radek Čech Preparation of HSR Network in the Czech Republic Network planning  Central Europe, Via Vindobona

The paper introduces the current status of preparation of the HSR network in the Czech Republic which is considered to be a crossroad of the Central Europe. It focuses mainly on the concept background and characteristics of technical design of individual HSR lines at different stages of progress. Using concrete examples, it presents the long-term demographic, environmental and transport gains generated by HSR implementation in the Czech Republic. The paper will also cover the outreach and connections of the Czech HSR network to neighbouring countries, such as the concept “Via Vindobona” which establishes a framework for intensive passenger railway connections between the national capitals with the prospect of achieving a four-hour journey time on the Berlin – Prague – Wien route. The Czech HSR network is thus key contribution to wider integration of the Central European region.

4514 2 September 2022 at 3:47 pm Svetlana Grechka Accessibility Requirements beyond the US: a close look at the Kingdom of Morocco Inclusive and accessible facilties for all  stations and facilitites, accessibility requirements

High-speed rail stations vary from typical transit stations in many ways. They are much larger, serve different trip purposes and have different characteristics. High-speed rail stations are also multi modal “hubs” with direct connection to local and regional transit and rail systems. Since they serve such an important and expansive purpose, they are a key part of the transit infrastructure serving the public.
While these stations offer an inter-modal transportation network and accommodate large numbers of passengers, special attention should be paid to a particular part of the population, those with disabilities. Since these individuals are a part of our community, they should have the unhindered access to public transportation.
Even though most countries have their own laws and requirements addressing accessibility, it is beneficial to learn from each other, as there is always room for improvement. In doing so, designing the transit stations may require breaking the mold of generally accepted transit design principles to incorporate best practices and collective knowledge of the subject.
During this presentation, the author will carefully analyze the 2010 ADA Standards for Accessible Design in the US and the initiatives were taking place in the Kingdom of Morocco. The author will explore the various considerations to meet the needs of the public that will be in line with achieving a goal of delivering safe and accessible transportation services that promote improved quality of life.

4515 2 September 2022 at 3:56 pm Svetlana Grechka Lessons from the Safety Certification of a Commuter Rail project in the US

Safety is the top priority for transportation projects, and it continues to gain attention from all stakeholders. To create secure, sustainable, and efficient modes of transportation, the continuity of a safety certification throughout a project is critical. This certification requires a close look at project implementations during the design, construction, and final verification through activation.
In this paper, the author will present on the safety certification process implemented on the North Metro Commuter Rail project lead by Regional Transportation District (RTD) in Denver. She will explore the specific steps were taken for the project to be safety certified and will cover the lessons learned that can be applied for future rail projects.

Functional & technical specifications  Night Train, High Speed

With growing demand for night trains in Europe, we set out to conceive and engineer a high speed night train with interoperability capabilities in order to create new opportunities for both businessmen and tourists. The train would be an electrical triple unit that would link major business and tourism hubs using both conventional and high speed lines in Europe. It would then split up to bring people closer to their final destination in the morning using slower tracks. It would also bring airline-style business class seats to the railway industry for better comfort and capacity.

The fully electrified network will cut carbon emissions by 70% compared to current car or bus transport, further supporting Egypt’s efforts in transforming its mobility to a more sustainable one.

4534 14 September 2022 at 8:34 am Shuji Sugimori A Study on the Mutual Enhancement of Regional Economy and Personal QOL along the Mumbai–Ahmedabad High–Speed Rail Corridor in India

Wider socio-economical impacts  Regional economy, Quality of Life (QOL)

High-speed rails (HSRs) have been developed in many countries and regions. The advantages of HSR as a mass passenger transportation are not only the economic benefits due to its speediness, but also its environmental advantages in terms of energy-efficiency compared to air travel and other modes of transportation, making it an effective contribution to sustainable development.
Among the various effects of high-speed rail, a direct benefit to users has been measured as an in-crease in gross domestic product (GDP) by the conventional cost–benefit analysis (CBA), which was institutionalized in the U.K. In recent years, the importance of capturing indirect benefits to non-users has also been broadly discussed. The indirect benefits of HSR can mainly be classified into two perspectives: regional economy and personal quality of life (QOL).
In this study, we modelled the mutual enhancement between those effects, and analyzed the in-direct benefits of the Mumbai–Ahmedabad high-speed rail (MAHSR), which is currently under construction as the first HSR for India, an emerging country with a rapidly growing economy. The indirect benefit for the regional economy along the MAHSR corridor was estimated by industry and by zone. In addition, the indirect benefit for personal QOL by individual’s attribute and by zone through the mutual enhancement with regional economy, was also estimated.
This method can evaluate the interregional disparity by identifying the differences in benefit by person according to age, income, etc., which cannot be evaluated based on a mass measure, gross domestic product (GDP), in the conventional CBA. Thus, this method can quantitatively evaluate “No one left behind”, as stated in the SDGs, and is expected to be utilized to aid in various future policy evaluations in a society with diverse values.

4539 15 September 2022 at 1:50 pm Martin Švehlík New HSR stations architecture in the Czech Republic Architectural design and placemaking  Central Europe, HSR stations

The planned high-speed rail system in the Czech Republic also includes building several new HSR stations. The presentation describes the design of the new transit hubs, which are the outcome of architectural competitions with international participation. During the preparation of the competition specifications and the evaluation of the submitted designs, there is intensive cooperation with SNCF experts. In particular, we utilize their forty years of experience to ensure the safety and smooth operation of links between all transport modes. Thanks to architectural competitions, we achieve an optimal design that provides both aesthetic quality and cost-effectiveness. With the help of these new stations, we will bring eco-friendly high-speed transport closer to more than half of the Czech population. High-speed rail will thus become a key contribution to a wider integration of the Central European region.

4540 16 September 2022 at 5:31 am Kenichi Kogayo Streamlining JR East Shinkansen track maintenance Track maintenance tools  Ballast, Rail

1. Features of JR East Shinkansen
We operate 5 Shinkansen lines. The total length of lines is about 1,100 km, maintained/managed by 9 track maintenance technology center.
Track structure mainly consists of 3 types: ballast, slab, and anti-vibration tracks.
2. Efficient track maintenance
The Shinkansen track system is maintained by rougly 1,200 staff, which will gradually decrease in 20 years. So, it is necessary to prepare a sustainable maintenance system for the future and we have made some improvements so far.
In mechanizing work, we have introduced multiple tie tampers which can be used even in turnouts and several types of rail grinding vehicles. However, one of the challenges is how to mechanize the work of replacing ballast and rails.
3. Dealing with the challenge
A) New ballast excavator
Deteriorated ballast had been partially replaced by using a backhoe, but this progress was too slow, only 5 to 10 meters per night. Therefore, a new ballast excavator was introduced in 2016, improving it from 20 to 30 meters per night.
It bore another problem; we had to save train speed for ballast’s stability. Then, we introduced a new methodstabilizer machine in 2022 and enabled to increase the running speed to 210 km/h.
B) New Shinkansen rail exchange system (REXS)
Rail replacement work is carried out in 4 processes: (1) preparatory work for transporting equipments, (2) transporting/unloading/welding new rails, (3) replacing/welding rails, and (4) transporting old rails. The REXS was introduced to streamline the overall processes in 2017.
For the task (2), REXS increased the loading capacity and decreased the welding work time.
For the work (3), REXS increased the length of the replacement work per night. REXS brought a huge improvement on working time.
5 years have passed since we introduced REXS, and total of 418,000 meters rails had been replaced without any big accidents. We are still working on maintenance tasks by using this system.

4544 19 September 2022 at 2:24 pm Giovanni Luca Giacco Giacco High-Speed rolling stock rostering and maintenance optimization Maintenance  Rolling Stock, Maintenance

Rolling Stock Management (RSM) is the main cost factor for Rail Undertakings operating in a competitive market. In order to reduce railway operations costs, every company must address the joint problem of rolling stock rostering and maintenance scheduling since they are strongly related parts of the same problem. This work describes a complex optimization framework for rolling stock ros¬tering and maintenance short term scheduling at a busy workshop in case of acyclic timetable. New formulations are provided and a scalable application using HPC architecture with parallel and distributed computing algorithms was developed. The general problem addressed can be defined as follows: Given timetables, rolling stock assets, maintenance operations, a rolling stock circulation solution has to be computed with minimum costs, that are expressed in terms of the number of used asset units, empty runs, and train movements between station platforms and the workshop.
The assessment of the computation time shows how the proposed method can be also used as an effective tool to absorb real-time timetable perturbations while respecting the agreed level of service. A robustness analysis is provided in order to evaluate the schedule quality in case of short-term traffic disturbances altering the off-line plan of operations. The objective is to re-balance the use of workshop resources to compute a feasible schedule, i.e. a schedule of all workshop operations within the time windows given by the rolling stock rostering planner and perturbed by traffic disturbances.

4545 19 September 2022 at 2:28 pm Giovanni Luca Giacco Giacco Complex High-Speed Network Optimization Modal complementarity  Network planning optimization, Mulimodal Design

The growing demand for high-speed trains and the cut-throat competition with other operators pushes railway undertakings to increase rail transport services to better meet the demand and with clear implications on the company’s profit. At its first stage, the High-Speed Network appeared clearly isolated since it was not connected with other rail transports.
Nowadays, after a long evolution, the High-Speed Network plays a prominent role being the national mobility backbone with a strong effect on rapid transit areas as well.
The main achievement of our work is the enhancement of people connectivity by optimizing jointly the main stations clocks taking into account different means of transport and multimodal hubs. Our project focuses on developing complex mathematical optimization models and algorithms for the train timetabling problem with respect to travel demand and capacity constraints placing a specific emphasis on practical commercial and operational constraints such as paring time breaks, headway time, minimum connection time and passengers flows as well.
The complexity of the problem and the required short computation time make existing models and algorithms not adequate to find a near optimal solution especially in case of non-patterned services under high level of robustness constraints. To our knowledge, this is the first approach for such a complex timetable optimization involving hundreds of transports.

4548 20 September 2022 at 8:26 am Ignacio Sanz Junoy Management of Adif stations in a context of passenger services liberalization Management of Rail capacity  liberalization

Stations are a fundamental element in the provision of rail passenger services.
Given the increase in lines and demand, the stations become congested. The flow of passengers increases considerably and there is not enough space for the management of services such as traveller information, ticketing, VIP rooms, board loading and unloading logistics services (catering) or PMR among others. It is also necessary to provide fair and balanced conditions to the incumbent and the newcomers, sharing the congested spaces. With the liberalization of these services, two main issues are raising. Firstly, the stations become congested, they are bottleneck. Secondly, different spaces under different regulation and divergent pricing. There is no homogeneity in the regulatory framework of the European Union.
One of the great challenges when managing a station operating in the liberalization context is deciding on the service provision model, following the principle of cooperation. Depending on who is responsible for the service, it can be managed by the infrastructure manager, by third parties or under the model or self-provision.
The paper develops each of these parts and shows two practical examples, on PMR assistance, and on board loading and unloading logistics services. The difficulties, challenges and solutions that Adif has established for its management are explained.

4550 20 September 2022 at 9:54 am Javier López Ordieres Adif in the process of liberalization the passenger services Network capacity management  Liberalization

Spain has opened in December 2020 the market for the domestic passenger services in compliance with the Fourth Railway Package. However, the process of liberalisation started some time ago. During this period Adif has analysed the open market process in other European IM. Adif carried out contacts and made bechmarkings with other IM about allocation capacity, provision of services in rail passangers stations, etc. The intention for this was to obtain information and feedback for guaranting some aspects in the liberalization as transparency, no discrimination, optimization of capacity and its use, customer vision, quality of services (punctuality) and plurality of candidates and lines.
During the process, Adif has worked together with the Spanish Rail Regulatory Body.
The evolution towards an open market has implied for Adif the declaration of congestion of some sections of the network and specially the stations Madrid Puerta de Atocha, Madrid Chamartín and Barcelona Sants. Also, the Adif Network Statement has been updated. Additionally, Adif has introduced the possibity to sign a framework agreement (10 year) with the operator. This will allow a better financing for those candidates that do not have the ownership of rolling stock.
The approach of Adif for the liberalisation process has consisted in the offering of 3 packages (A, B, C) for three high-speed corridors. After applying the priority criteria established in our Network Statement, Adif-AV resolved to award them to RENFE (A), Iryo (B), and Ouigo (C).
The main consequence of the open market has been the increase of 65 % (average) of the offer of rail transport on the three corridors. Henceforth, the implementation of more services and more operators will be beneficial for Spanish and European citizens.
The latest available traffic figures will be presented, analysing the real impact of this new environment.

4552 20 September 2022 at 10:09 am Jonathan Sánchez García The role of railway in the fight against climate change Emissions to Air, Land and Water   climate change

The Climate Change is one of the biggest environmental problems on the world, so that the Spanish Government has set targets by 2030 aiming to reduce greenhouse gas (GHG) emissions, to increase renewable generation sources and to improve the energy efficiency, mainly. All this with the aim of being carbon neutral by 2050.
To achieve these objectives, action must be taken in the transport and mobility sector, and it is here that the railway must play a leading role.
Adif and Adif AV have a Strategic Plan by 2030 in line with the Sustainable Development Goals (SDG) of the 2030 Agenda of the United Nations (UN). So, the sustainability is one of the four pillars of our Strategic Plan.
In this context, from the environmental point of view, Adif and Adif AV show their commitment to sustainability through their Plan to Combat Climate Change 2018-2030

The Plan establishes goals in mitigation, aims to reduce of energy consumption through improvement energy efficiency and to reduce GHG emissions. Likewise, the Plan aims to reduce the carbon footprint (scopes 1 and 2) of Adif and Adif AV by at least 86 percent if the purchase of green electricity (with guarantee of origin certificates) is taken into account. Our commitment is to achieve carbon neutrality by 2050 as the maximum horizon, commitment it has signed with the UIC.

In adaptation, the Plan also contemplates the inclusion of the assessment of vulnerability to the adverse effects of climate change in railway projects from 2020, as well as clauses related to climate change in all contract documents from 2025.

Adif supports the principle that rail projects can be covered by sustainable financing mechanisms. This includes the use of European Regional Development Fund. The projects under this umbrella include the adaptation to climate change of infrastructures (mainly due to the mitigation of the climate change effects and resilience).

4555 20 September 2022 at 10:33 am FABRICE MORENON HSR stations as hubs of green mobility Energy – Efficiency and renewable sources  Hubs Green, Green Mobility

Low greenhouse gas emissions, reduced noise exposure, energy savings, societal benefits, the advantages of railways make them a sustainable transport solution.

The freedom to travel brings individuals and regions closer together. By drawing on the diversity of shared transport modes on offer, mobility companies offer, with and around the train, solutions adapted to each individual. The High-Speed Train (HST) emits 25 times less CO2 than the private car and 45 times less than the plane. By reaffirming the place of the train as the backbone of sustainable mobility, railway companies are responding to the need to combine freedom of movement with environmental protection.

The CO2 emissions of a train journey are lower than those of other means of transport, such as cars or planes. When travelling within the country by plane or train, the journey time is usually equivalent and less polluting for the train. A journey from Paris to Lyon takes 2 hours by train compared to 1.30 hour by plane (excluding the time spent waiting at the airport), therefore the duration is equivalent for a less polluting journey.

An important component of the journey is the station. Stations are the gateway to sustainable mobility, as the train is one of the lowest CO2 emitting means of transport. They must make people want to take the train by being exemplary in terms of environmental standards.

The SNCF’s challenges are to set an example and to innovate through four priorities: using cheaper and greener energy, developing eco-design, achieving zero non-recycled waste and promoting train-bike intramodality.

4556 20 September 2022 at 10:36 am Arturo Pastor García The Spanish High Speed Network facing an increase in demand due to the liberalization of passenger traffic Network planning  congestion, rail network development

Spain, with more than 3,700km, has the rail network with the most kilometers of High Speed in Europe and the second behind China. In addition to being a backbone of the economy, it is a key driver for achieving the transport decarbonisation objectives.

In 1992, the Madrid-Seville line was inaugurated, connecting cities accounting for 20% of the Spanish population at that time. Thirty years later, approximately two thirds of the Spanish population (68%) can benefit from a network that has increased the number of potential users around 400%.
These more than thirty years of High Speed have allowed Spain to develop one of the most modern and advanced railways of this type in the world.

The paper explains the High Speed Rail Network in Spain, how it is working and the necessary changes that have to be undertaken due to the liberalization of passenger transport and the increase in demand. The goal is an optimal use of our Network, solving the congestion of our infrastructures and offering an infrastructure prepared to absorb the demand expected by liberalization. This will allow us to democratize access to High Speed Rail through more affordable prices that cause a modal change from the private vehicle to the train, reducing emissions per passenger

In this sense and with the aim of completing our high-speed network, in recent years we have put into service several lines as, the Madrid-Galicia High Speed Line, some sections of the High-Speed Line for the connection with the Portuguese border (between Plasencia and Badajoz), some sections for the connection with the French border through the Basque Country, the Chamartín-Atocha -Torrejón de Velasco section, and the arrival of High Speed to Murcia. We have also inaugurated a new Traffic Control Centre in León which works in network with other centres that we have throughout Spain, with systems that are a reference in the world. This allows us to optimize capacity and efficiently manage our large rail network.

A transportation construction project is typically viewed as the active phase of building public infrastructure. It is a series of phases with a beginning and an end, all of which need to be executed for a successful project.
Project closeout activities are important parts of the project and perhaps some of the hardest. They ensure the recording of project documents and deliverables, accounting and archiving organizational assets, making final payments, releasing resources, and communicating with the stakeholders during the stage of a project completion.
The main challenge of this project phase is shifting focus from execution to closeout which requires a change in mindset from being “done” to being “complete”. Project closure is not just a milestone, but a critical process for a successful conclusion of a project.
This presentation will highlight the specific steps that were taken for the North Metro Commuter Rail Line project to be concluded and will cover the lessons learned that can be applied for future rail projects.

High-speed railway, key technologies

China high-speed railway has made remarkable achievements. In order to promote China high-speed railway to the world, we must comprehensively summarize the key technologies of China high-speed railway. The high-speed railway is a large and complex modern system consisting of multiple subsystems, including: permanent way engineering, high-speed trains, traction power supply, OCS technology, train operation control, transportation organization, passenger transport services, operation and maintenance, disaster prevention and safety, etc. With the purpose to optimize the high-speed railway system, it is necessary to match and coordinate various subsystems with different functions. This paper first briefly introduces China high-speed railway, then elaborates the key technologies of each subsystem of China high-speed railway, and then, in related sections, briefs the ticketing system and the disaster prevention and safety guarantee technologies of China’s intelligent high-speed railway, finally, makes some suggestions on strengthening the promotion of China high-speed railway to the world.

4571 26 September 2022 at 12:27 pm BAKI BURAK ACIL High-Speed Rail: Is the speed of the planet accessible to all? An accessibility review for a High-Speed Station at the capital of Türkiye: Ankara High-Speed Train Station Inclusive and accessible facilties for all  accessibility, inclusive

Ankara High Speed ​​​​Train Station Building, which was opened on October 29, 2016 and is in the service of the public with a daily capacity of 50.000 passengers, is expected to be used by the public a lot with its platforms, shopping center, cafes and restaurants, cinemas, meeting halls and hotel where 12 high-speed train sets can dock at the same time; appears as a building complex. High-speed train journeys can be made to Eskişehir, Istanbul, Konya and Karaman from this huge building, which spans an area of ​​194.460 square meters in total. Well, can this great destination, where the Sivas line will be opened soon, inclusive for everyone, is it accessible to everyone?
With the law 5378 enacted by the Republic of Turkey in 2005, ensuring the accessibility of public and private institutions is a legal requirement. Pursuant to the “Convention on the Rights of Persons with Disabilities” (CRPD), which was opened for signature by the UN and to which the Republic of Turkey completed its ratification process on 28.10.2009, full and equal enjoyment of all human rights and fundamental freedoms by persons with disabilities was encouraged. With the process that started with this contract, the issue of accessibility has also entered the agenda of the transportation sector, and project design and implementation studies for the accessibility of stations and stations in railways have accelerated.
Does Ankara High Speed ​​​​Train Station, whose accessibility must be ensured by law, perform its function as an inclusive and accessible station for everyone? In this study, it is aimed to reveal the results in terms of accessibility by examining the “Accessibility Monitoring and Inspection Form for Buildings” issued by Ministry of Family and Social Services, of Ankara YHT Station, which has been serving for 6 years, and to shed light on the design processes of the YHT Stations to be built later.

Maintenance (incl. tools)  Rail surface treatment, High-power diode laser

In the current study, high-power diode laser surface treatment was implemented to R260 grade
steel with three different processing temperatures (1100 C, 1200 C, and 1300 C) at the laser
power of 1750 W and scanning speed of 6 mm/s, in order to identify the effect of various
processing temperatures on the mechanical and metallurgical performance. According to the test results, the
laser-treated sample at 1300 C showed much better mechanical performance among the other
laser-treated ones. It was found that the laser-treated sample at 1300 C had about 3 times
more surface hardness, a 43 pct increase in yield strength, and a 53 pct increase in toughness
value compared to the untreated sample. Mietallurgical iexaminations showed that this surface
treatment did not only generate a martensitic structure with a certain depth but also provided
the formation of a fine pearlitic structure contributing to an increase in the mechanical
properties. Consequently, it was found that the processing temperature is one of the critical
factors affecting the mechanical properties in the laser hardening process. Moreover, the results
showed that this treatment method may be an alternative method in order to increase
mechanical properties of existing rail steels online without the need for rail disassembly,
reducing operational costs.

New trends, mobility changes  Customer decision criteria, Rail competitiveness

Understanding customer preferences to make rail travel more attractive and increase rail modal share is valuable for decision makers in the rail sectors including operators, infrastructure manager as well as policy makers. Yet, most customer research relies on identifying attributes that generally matter for travelers, resulting in a wide range of different criteria (e.g., comfort, speed, price, safety, accessibility). While these criteria might be relevant for customer satisfaction, they hardly shed light on what actually makes people to decide in favor of or against taking the train, compared to alternative modes of transport like the car.
To better understand actual decision criteria, we have conducted a conjoint experiment with more than 6,000 participants across 9 countries in Europe, North America, and Asia, simulating more than 100,000 hypothetical travel decisions. Results show that across geographies, price is by far the most important decision criterion, followed by the overall travel time. In comparison, additional features like comfort, added services, or sustainability considerations matter far less – while customers generally state that these aspects are important to them, for the actual decision making they are hardly relevant.
The findings imply that decision makers in the rail sector that are concerned with raising rail modal share should first and foremost focus on price and travel times. For long-distance trips, high-speed railway connections therefore have a clear competitive advantage for becoming a widely used means of transport. In most cases, only high-speed lines are able to compete with car or plane in terms of travel time. The study with its unique database thus underlines the importance of high-speed rail. The methodology of the study also offers a tool for high speed operators to strike the right balance in pricing, speed, service offering by customer segment.
