A novel method for assessing the seismic resilience of railway stations is introduced. With this method, a railway station is divided into five constituent systems. The structural components, nonstructural components, and especially professional equipment that affect the functions in each system are identified and analyzed. Significantly, a new calculation method for seismic resilience indices, encompassing repair cost, repair time, casualties, and resilience grade, is proposed. Additionally, the complete seismic resilience assessment process is outlined. Furthermore, a case study was conducted on a typical railway station in China to demonstrate the application of this new seismic resilience assessment method. [ABSTRACT FROM AUTHOR]

In densely populated cities, the increasing popularity of railways and urban rail transit interchange hubs has led to the extensive use of land resources and raised concerns about the environment, especially the inevitable noise and vibration impact. This study aims to identify the propagation patterns of roof structure vibrations in railway complexes through experimental research, with the premise of maintaining normal train operation and safety, in order to lay a foundation for developing vibration mitigation strategies and optimizing functional layout. The results found that the train-induced vibrations are strongest at track level, but decrease as they move vertically and horizontally. Vibrations from passing trains are most noticeable within a single floor slab and beams, with minimal transmission at the base of columns. [ABSTRACT FROM AUTHOR]

The corona virus disease 2019 (COVID-19) pandemic has increased awareness towards maintaining physical distancing during transportation-related activities. This study presents a microsimulation model to explore operational measures to maintain physical distance among railway station passengers. The secondary and primary data obtained from field surveys are utilized to construct and calibrate the model. The peak hour data is employed to investigate the worst-case conditions. The calibrated model is then utilized to evaluate several operational measures, i.e., changing the headway, increasing the train capacity, increasing the train door duration, and changing the train door rules. From the simulation, it is found that changing the train door rules was ineffective if it was individually implemented. It is concluded that a combination of operational measures provides additional benefits for maintaining physical distancing among passengers.

The present research seeks to outline a common ground between the notions of urban aesthetics and inclusive planning by taking Siliguri Town station and its adjacent market as the cases. This article attempts to redirect the study of urban geography of Siliguri city away from macro-level analysis of space, which sometimes generates crude generalized discussions about the spatial development of urban landscapes, on the side of a more vigorous contemplation and critical consideration on the scope of micro-level planning alternatives for the city. Toward this objective, the research methodology is grounded on the analysis of historical databases, intensive field observation, and qualitative interviews. Through ten in-depth semi-structured interviews with key stakeholders including local body representatives, railway officials, planners, investors, as well as civil society organizations in Siliguri City, this study seeks to emphasize the factors that stakeholders in the city consider to be essential for the micro-scale development of Siliguri Town station neighborhood and its long-term effects on a number of actors. Findings from the interviews indicate that Siliguri Town station and its neighboring markets, such as Mahabirsthan and Hawkers' Corner, are continuously growing as the places of urban contestation and struggle. To critically address these contestations, the research argues for the resurgence of Siliguri Town station neighborhood as the key urban territorial form for collaboration among central, state, and local government authorities as well as private players. The principal outcomes of this research, therefore, are expected to provide some micro-level planning alternatives, which can pave the path for an inclusive and planned production of urban space around Siliguri Town railway station, representing the heart of Siliguri city.

The safety situation of railway stations is facing great challenges due to the characteristics of huge transport task load, fast operation speed and larger station scale. Based on this, this paper proposes a decision-making method for safety risk factors of high-speed railway stations, which combines fuzzy fault tree (FFTA) and Bayesian network (BN) algorithms. Firstly, the basic risk factors and events of each subsystem of high-speed railway station in the actual construction and operation process are statistically analyzed and modeled, and a total of 22 basic events affecting the safe operation of railway stations are determined. Secondly, the limitation of data collection is overcome by means of expert experience evaluation, scoring and fuzzy rough set theory. Then, the fusion structure of fault tree analysis and Bayesian network algorithm is used to overcome the shortcomings of single algorithm in data processing ability and accuracy, effectively and accurately reveal the logic and probability relationship between safety risk factors, and four basic events such as the lack of technical means to master the station resource status and operation progress are identified as the main influencing factors. Finally, through sensitivity analysis, the risk reduction value importance (RRW) indicators of 22 basic events that affect the safety of high-speed railway station construction and operation are obtained. The results show that the RRW of the 4 main influencing factors are all greater than 15%, which verifies the correctness of the results obtained by FFTA and BN. The proposed decision-making method for safety risk factors of high-speed railway stations can realize accurate positioning and decision-making of key indicators and corresponding probabilities affecting the safety of high-speed railway stations, thus providing effective reference for ensuring the safe operation of high-speed railway stations.

With the comprehensive development of China's high-speed rail and intercity rail construction in recent years, the so-called "HSR new city" or urban complex of railway station is becoming the "new engine" for the development of many cities along the lines. This paper takes the high-speed railway stations and intercity railway stations on the main lines in China as examples to analyze the spatial spillover effect and spatial differentiation of railway stations on the surrounding areas. Due to the lack of relevant socio-economic data, this paper applies DMSP/OLS and NPP/VIIRS satellite lighting data; combined with multi-period DID model and spatial buffer analysis to evaluate the above effect. The research results show that the opening of the railway station has a significant spatial spillover effect on the surrounding areas. And the spillover effect decreases rapidly with the increase of distance. The threshold range of the highspeed railway station is about 7 kilometers, while the threshold range of the intercity railway station is about 5 kilometers. This spillover effect has obvious heterogeneity according to scale of station, and it is bigger in medium-sized sites. In terms of regional performance, this spillover effect is most at railway stations in the Central China, followed by the Western China, and relatively weak in the Eastern China and Northeast China. According to the empirical results, it is also found that in order to take advantage of the spillover effect of the railroad station, the distance from the railroad station to the central city should be 10-40 km.

The station–city integration development strategy, guided by the Transit-Oriented Development (TOD) model, has enhanced the coupling relationship between rail transit stations and urban areas. Walking, as a core mode of low-carbon urban transport, plays a significant role in the connectivity between stations and urban areas and in the rate of passenger flow dispersal. During peak periods, large volumes of passengers flood the streets, forming complex and diverse walking paths that penetrate urban neighborhoods. Route choice is a complex decision-making process influenced by both subjective and objective factors. Previous studies on pathfinding activities have often focused on either subjective or objective factors in isolation, with limited research on their interaction. This paper establishes a comparative analysis framework based on the translation of subjective and objective information and behavioral feedback mechanisms. Using Lvcuo Station, a transit station on Xiamen's Metro Line 1 in Fujian Province, China, as a case study, we collected walking data from 410 passengers through field surveys. We used the Kappa consistency coefficient test method to analyze the performance of the interaction between the objective environment and subjective environmental cognitive factors when pedestrians exit the rail transit station and walk to their destinations. We also used multinomial logistic regression (MLR) to analyze the correlation between subjective perception variables and objective built environment variables and to consider the influence of individual pedestrian characteristics and attributes on path selection. The results revealed the following: (1) Overall, there is a significant deviation effect of subjective and objective factors on passengers' pathfinding behavior, with some spatial correlation with the built environment of the streets. (2) The consistency of influences on walking activities varies significantly across different travel periods, distances, and purposes. (3) Visual elements, urban life with a bustling atmosphere, street permeability, and route connectivity positively correlate with subjective perception while "supporting walking facilities" and "meeting consumption needs along the way" negatively correlate with subjective perception. These findings underscore the need to enhance the understanding of the built environment in the street spaces within rail transit station areas from the perspectives of pedestrians to improve the walkability of these streets.

This paper presents a preliminary study of a 25 kV–50 Hz railway substation power supply system. The control of a back-to-back converter based on modular multilevel converter (MMC) technology was investigated to fit with the power quality requirements of the application. One of the main challenges is the presence of constraining load conditions, under which the train circulation variability, low-frequency harmonics and critical power transients can notably decrease the power quality and lead to instability. In order to address this, cascaded controllers based on resonant controllers are proposed to ensure the desired performance. Furthermore, balancing voltage algorithms are added to avoid stress phenomena and additional losses in the studied power conversion interface. The paper presents the design of the control stages and demonstrates the robust performance of the system using a realistic loading condition of a railway substation. [ABSTRACT FROM AUTHOR]

An environmentally conscious architectural design of a railway station can have a substantial influence on government spending. Nevertheless, an extensive collection of guidelines for using sustainable design principles in the construction of a railway station can provide several advantages. The goal is to review design visions for railway stations in Thailand, as reflected in student theses and government proposals, from 1983 to 2022 for sustainable design aspects in tropical climates. We perform an analysis of architectural design aspects including service areas, shape, entrances, roofing, style, and development in order to uncover design trends and possible areas that may be enhanced. Station designs are mostly characterized by curved and gable roofs, with 3D curved buildings being the next most common feature. High speed rail (HSR) stations stress local cultural elements in their major entrances while also improving passenger flow. Public buildings frequently employ curved or gabled porticos to achieve a majestic look. Although university theses place a high importance on conceptual design and functionality, it is essential to also consider cost-effectiveness. Key design considerations for future railway stations are transparency, connection, efficient mobility, and cost–time efficiency. The research uncovers deficiencies in user-centered design for thermal comfort and inclusiveness (design-for-all) in Thailand's tropical environment. Addressing these aspects is critical for future sustainable railway station design evaluations. [ABSTRACT FROM AUTHOR]

Purpose. To improve the method for standardizing the duration of the shunting operation of assembling cars on one track. This can be achieved as a result of solving the following research problems: development of a method for searching the optimal order of assembling cars on one track; distribution parameters estimation of the random value of the duration of shunting operation of assembling cars on one track based on calculation experiments. Methodology. During the research, the methods of theory of railway operation, dynamic programming and mathematical statistics were used. Findings. Research on the assembling process of car group to one track established the distribution parameters of the random variable of time spent for shunting. In the course of the research, the problem of choosing the optimal order of shunting operations during car assembling was formalized and solved as a problem of dynamic programming. The time spent for shunting work was chosen as the optimality criterion. The paper considers the possibility of approximating the data of calculation experiments by analytical dependencies. It was found out that the use of linear polynomials with interaction allows obtaining dependencies describing time standards with a relative accuracy of ±5 %. Originality. The method is improved for developing the time standards for shunting work, which, unlike the existing one, is based on the performance of a series of calculation experiments, each of which solves the optimization problem of finding such an order of assembling cars that ensures minimum time consumption for shunting. Practical value. The methods developed in the work and the dependencies obtained allow improving the quality of decisions made when developing technology and designing railway stations and sidings of industrial enterprises.

Abstract Nowadays, mobility represents the main productive process: this means that territorial sustainability must necessarily include sustainable movements as a key component. The increase in transport entity and transport routes, economic convenience, and, last but not least, a higher environmental awareness, are leading to higher consideration of the use of railways. In this framework, railway stations represent complex objects requiring significant material flows, which make up their ecological footprint. In this sense, a railway station is the last industrial plant to be accepted in contemporary cities. The last 2 years of pandemics have amplified both the need for tangible sustainability and the demand for active mobility-friendly cities. Discussing the sustainability of a station involves examining and measuring its ecological footprint, to provide active support to the targeted planning and design of mitigation measures. Their impact and effectiveness are certainly amplified by the natural central role of the railway stations. And what if the pursuit of sustainability for the railway stations could be intertwined with the search for quality collective spaces? The answer is positive. The proposed algorithm allows shifting from a qualitative view (so to say, measured on a flat-rate basis), to a quantitative view of the possible improvement actions on the operation and maintenance processes of railway stations. Moreover, through minor adaptations, it could also be applied to industrial or residential processes.

Railway stations are massive infrastructures through which people, products, materials, and energy flow every day. They usually gather a multitude of functions and provide a wide range of services to users based on their respective specific features. Thus, railway stations have the potential to play a critical role in reshaping our cities in a sustainable manner by facilitating intermodality, green and active modes of transport and logistics, and by gathering proximity services. In this reshaping process, implementing effective and seamless mobility, as well as the proximity of services, are key challenges. However, no urban transformation process can take place without the involvement and commitment of the respective stakeholders. This paper aims to form an understanding of the views these stakeholders have towards the potential of railway stations transformation, for the broad European context, to carve out first paths towards actually achieving that transformation. This study analyses a wide range of inputs and considerations made during a series of workshops held in 2021 by the EIT Urban Mobility where experts from a wide range of fields exchanged their experiences and ideas around the topics of urban mobility and public realm. In this process, railway stations emerged as a key player to meet the challenges of cities’ sustainable development. After analysing their potential and exploring policy obstacles that are currently hampering such a transformation, this paper suggests a series of recommendations to better exploit railway stations, gained from the stakeholders’ perspective.

This paper argues that the Heritage Railway Stations Protection Act is an example of symbolic legislation that bulwarks a façade of government protection and democratic participation in the face of relative public political powerlessness. Rather than protect railway stations, the Heritage Railway Stations Protection Act creates an illusion of preservation. The Act's weak regulatory framework, the emotionality and legal complexity of railway station protection, and the disparate political experience of railway companies versus heritage advocates all imply the Heritage Railway Stations Protection Act is symbolic legislation. This paper challenges discourse analysis's predominance within critical heritage studies. It demonstrates the importance of considering heritage law's real-world effects when analyzing its political import. It calls on critical heritage scholars to consult a broader range of sources and consider the political implications of heritage law beyond recognition. [ABSTRACT FROM AUTHOR]

The decision-making problem of station location scheme is an important part of the overall planning scheme of railway lines. The tourism-oriented railway station location problem is to complete the station location on the basis of giving priority to tourism demand. Based on the characteristics of tourism orientation, this paper analyses the influencing factors of railway station location and establishes the corresponding decision-making index system of location scheme. Aiming at the characteristics of station location problem as a multi-objective attribute decision problem, considering that prospect theory can effectively deal with the psychological expectation factors of decision makers, a new decision-making method that can deal with qualitative and quantitative indices is proposed by combining vague theory which is quite effective in dealing with fuzzy problems. Taking the decision-making of railway station location scheme as an example, the decision-making method is calculated and verified. Through verification, it can be found that the proposed comprehensive decision-making method is effective and practical, and the proposed method can provide decision support for tourism-oriented railway station location.

Active modes can play a key role in the transition toward sustainable urban mobility, and transport systems should be designed to support and incentivize them. For instance, walking accessibility to main urban centralities is a factor to pay attention to, as well as the way in which pedestrians perceive the characteristics of the infrastructure and the surrounding environment should also be considered. This study proposes a method for computing a walkability index of the paths for accessing transport nodes (e.g., railway station). The index is based on individuals' perception of walkable infrastructure features (e.g., kerbside width, presence of urban furniture, greenery, etc.). It allows having a more realistic view of the catchment area of the node and to identify policies for improving pedestrian accessibility. The method has been validated using an ad-hoc survey in the area of the Milano Rogoredo railway station (Italy). The map of the estimated walkability indexes is consistent with the real conditions of the Milano Rogoredo neighbourhood and allows for identifying those areas where walkability can be improved.

Introduction. The article considers the determination of the impact velocities of empty and loaded Class 2 dangerous freight cistern cars on a gravity hump, the forces acting on the car through the automatic coupler, as well as the accelerations acting on the loading and unloading, safety valves and elements of the tank shell interior. Currently Class 2 dangerous freight cars with Classification Code 2112 and UN numbers 1011, 1965, 1969, 1978 could be shunted over the gravity hump only with a shunting locomotive, backing off with extreme caution, without jerks or sudden stops. This limitation prevents shunting gas cistern cars on automated gravity humps, which complicates shunting operations during train formation.Materials and methods. Impact test of a cistern car alternately equipped with cushions of Classes T1, T2 and T3 with measurement of speeds, forces and accelerations.Results. The maximum permissible impact velocities of the cistern car are determined.Discussion and conclusion. According to the test results, as well as the GOST 32913–2014 requirements, the authors state that the implementation of the previously developed technology for shunting Class 2 dangerous freight cistern cars equipped with Class T3 draft gears on gravity humps, with a maximum approach speed of 3 km/h complies with shunting safety requirements.

The recovery of past architecture through 3D modelling is an important challenge today to the preservation of heritage. Decisive support for the interpretation of architecture can certainly come from historical images and old photographs that fix a portion of space at a specific time, keeping it unchanged over the years. This acquisition is decisive for studying architectures of the past that can be reinterpreted and analysed. Photos, in fact, capture the advance of time and the life of a building at a precise historical moment, becoming essential documents for the study and knowledge of heritage. An additional advantage is when these old images can be processed through Structure for Motion procedures and, the results obtained, used as support for a 3D model of buildings that no longer exist. The work shows an interesting pipeline applied to the Caltanissetta Centrale Station and the possibility of “recovering”, even if virtually, a phase of its architectural evolution through the integration of photogrammetry from historical images and 3D modelling. The case study is an opportunity to analyse the procedure still under development, as well as to identify the main difficulties encountered in this process and possible future developments.

In the nineteenth century, the impact of railways on urbanization was significant, despite initial predictions that its role would be limited to transportation. The presence of a railway station had impacted the urban fabric of Lahore during the colonial rule. It was the first purpose-built building by the British and it started the new era of urban expansion. Eventually, railway development turned out to be the fourth major settlement of Lahore. The objective of this paper is to highlight the contribution of railways in shaping the form and growth of Lahore. The methodology employed for this study consisted of collecting both primary and secondary data, followed by a comparative analysis of the urban context of pre-colonial Lahore and its development post the introduction of railways in the city.

This article aims to analyse the process of connecting the railway and the port of Setúbal within the development of sustainable urban policies. Since the nineteenth century, cities have faced challenges concerning the logistics of transportation. The urban specificities of port cities attracted the attention of experts in the mid-twentieth century, after some cities had relocated or restructured their port areas. Consequently, by the end of the twentieth century, intermodality became a fundamental tool to guarantee a sustainable urban plan. Currently, the sustainability paradigm has increased the concerns about port cities, due to their environmental, social, and economic qualities. This article aims to explore the historical relationship between the railway and the port of Setúbal. Focus is placed on the attempts to develop an intermodal system in Setúbal, while confronting it with its urban development. By discussing the restructuring process of the port of Setúbal since the arrival of the railway, this paper provides an overview of the interests and actors involved in the connection between these infrastructures. The historical analysis of the port-rail infrastructure reveals the urgency of this kind of understanding for current and future sustainable urban planning. [ABSTRACT FROM AUTHOR]

This study investigated the air quality and ventilation systems of 22 public toilets in 10 railway stations in China. Approximately 80% of public toilets meet the standard for ammonia concentration in Class I toilets, while 20% exceed the standard. It was found that the concentration of pollutants is mainly related to the number of toilet users and the ventilation system. In 20% of public toilets, the change in ammonia concentration was delayed by about 1 to 2 h with the change in hourly service number. In order to improve the air quality, a design method for calculating the number of toilet cubicles was proposed. Results show that the service capacity of the cubicle per hour (SCCH) of a female toilet is 12, the SCCH of male toilets is related to the ratio of squatting pans to urinals (RSU), which is suggested to be 1:1~1:0.8, and the corresponding SCCH is 16~20. Then, the effect of different ventilation forms was simulated by computational fluid dynamics (CFD) 2019 software. The results show that the bottom exhaust was better than the top exhaust and that the fresh air supply system is unnecessary. The recommended ventilation rate for toilets is 20 air changes per hour (ACH). The scale design method of toilets proposed in this paper was meant to address the gender imbalance and avoid queuing and provides a reference for the renovation and design of public toilets.

Predicting passenger flow is crucial for effective management and safety in railway stations. Accurate prediction of passenger flow facilitates effective allocation of staff tasks, enhances the efficient utilization of waiting areas, ensures passenger safety, and promotes a smooth travel experience for passengers. However, accurately establishing the spatial-temporal relationship of passenger flow within the station and predicting the passenger flow in each region and time period is challenging due to the varying waiting habits and train preferences of each individual passenger. In this paper, we propose a Residual-RNN-Channel Spatial-Temporal Graph Convolutional Network (RRC-STGCN), which utilizes the channel attention mechanism and residual structure. The model divides the data with a time dimension into multiple periods, capturing spatial-temporal correlations through the channel attention mechanism, and extracting spatial-temporal dependencies from the feature maps using the spatial-temporal convolution module. The model uses a residual structure to fuse features in order to enhance the accuracy of prediction results. In addition, we conduct a comprehensive experimental evaluation using a real dataset of railway station passenger, demonstrating that the RRC-STGCN model outperforms five well-known baselines. Moreover, we provide visualizations of the prediction results, effectively showcasing the dynamic changes in passenger flow in each waiting area.

For both passenger and freight transportation, railroad operations must be dependable, accessible, maintained, and safe (RAMS). In many urban areas, railway stations risk and safety accidents represent an essential safety concern for daily operations. Moreover, the accidents lead to damage to market reputation, including injuries and anxiety among the people and costs. This stations under pressure caused by higher demand which consuming infrastructure and raised the safety administration consideration. To analysing these accidents and utilising the technology such AI methods to enhance safety, it is suggested to use unsupervised topic modelling for better understand the contributors to these extreme accidents. It is conducted to optimise Latent Dirichlet Allocation (LDA) for fatality accidents in the railway stations from textual data gathered RSSB including 1000 accidents in the UK railway station. This research describes using the machine learning topic method for systematic spot accident characteristics to enhance safety and risk management in the stations and provides advanced analysing. The study evaluates the efficacy of text by mining from accident history, gaining information, lesson learned and deeply coherent of the risk caused by assessing fatalities accidents for large and enduring scale. This Intelligent Text Analysis presents predictive accuracy for valuable accident information such as root causes and the hot spots in the railway stations. Further, the big data analytics ’ improvement results in an understanding of the accidents’ nature in ways not possible if a considerable amount of safety history and not through narrow domain analysis of the accident reports. This technology renders stand with high accuracy and a beneficial and extensive new era of AI applications in railway industry safety and other fields for safety applications.

The former Pelícana train station is a earthen building that is located in the town of Pelícana in Valle del Elqui. Within the framework of a master's degree research and thanks to the research project Semilla Dicyt No 092090MP_ARQ of the Universidad de Santiago de Chile - Usach, it was raised to carry out a proposal for the rehabilitation of this abandoned space, revaluing it and putting it at the service of the needs of the sector. The study carried out responded to the characteristics of a projective type investigation, whose study events were: architectural deterioration and the needs of communal space. Research instruments were applied for the critical diagnosis of pathologies of the property and for the knowledge of the needs of common spaces by the local population, results analyzed with qualitative and quantitative techniques, respectively. Based on these preliminary results, the rehabilitation proposal was designed, which includes programs for sports, study, walking and meeting spaces. The investigation concludes in the development of an architectural rehabilitation plan for a building rooted in the sensitivity, history and identity of a locality, which has been consulted about its needs and interests in terms of the rehabilitation of this space, it is a plan that has highly gained feasibility, permanence and validity over time, which would guarantee the permanence of the ​​implicit architectural values in the building.

Featured Application: The solution was applied for the remodelling of the as-built documentation of railway constructions of Railway Administration of the Czech Republic. Building Information Modelling (BIM) is a modern approach to managing the process of preparation, realization and operation of building objects including their documentation throughout their life cycle, based on database agenda platform. The aim of our research is to analyze and innovate existing engineering procedures with the aim: 1. to remodel the existing CAD documentation into BIM for the purpose of public procurement, 2. to provide guaranteed data to the IS of the Digital Map of Public Administration and 3. to provide data for the design of new railway structures or their reconstruction. The aim of the case study was to evaluate the effectiveness of remodelling the existing as-built documentation of a railway construction into a common BIM data environment (CDE), in which further subsequent construction agenda should be managed for the remaining period of its life cycle. Using the documentation for construction realization of the railway station Šumice, this 3D documentation was remodeled into the BIM data environment CDE and alternatively also into the 2D GIS environment. The BIM data standard developed by the State Fund for Transport Infrastructure was analyzed during the documentation reworking. An important parameter of the documentation rework was the use of a geodetic reference system fully compatible with the cadastral system in the Czech Republic. It turned out that the general data standard is only partially applicable for railway structures containing many special objects and many objects requiring individual classification. The remodelling of existing graphical data proved faster and more efficient in a GIS environment (layer oriented) compared to the need for 3D remodelling in a BIM CDE (object oriented). Experimental results have demonstrated the effectiveness of remodelling underground technical infrastructure objects, while the visible surface situation is often more effectively captured by current progressive bulk data acquisition technologies. In a CDE environment, existing as-built documentation data can be efficiently stored and administered and progressively, for the procurement and execution of construction, purposefully remodeled only to the extent required in BIM or converted into an exchangeable Digital Technical Map (DTM) format for public administration.

Purpose. Improving the efficiency of interaction between enterprises that operate public and private railway infrastructure when performing cargo transportation and cargo operations. Methodology. The studies were carried out using the methods of the theory of railway operation and economic and mathematical modeling. Findings. The study found that the transition from a planned economy to a market economy along with increasing customer requirements for the composition and quality of transport services is an objective reason for an increase in carriage downtime at private sidings and junction stations, a shortage of track capacity and shunting locomotives. It is shown that the existing approaches to assessing the effectiveness of the interaction between train tracks of enterprises and mainline railways are aimed at improving the performance of the rolling stock and do not create incentives to solve the problem of the shortage of transfer and processing capacity of the railway infrastructure. Originality. The paper proposes an improved method for assessing the effectiveness of the interaction of participants in the transportation process when performing transportation and cargo operations on the private sidings of industrial enterprises, based on the time the infrastructure is occupied. This approach, unlike the existing one, encourages railways and industrial enterprises to jointly search for the best technological solutions for the use of public and private railway infrastructure. Practical value. The method proposed in the paper for assessing the interaction of participants in the transportation process makes it possible to separate station services in the tariff for the use of the railway infrastructure into separate services of service facilities and track access to them. This will create a competitive environment and encourage participants in the transportation process to use the existing railway infrastructure and develop a new one to obtain a synergistic effect more efficiently.
