“…Zhang et al [34] used the big-M method to minimize the train travel time and the maintenance tardiness; they added speed restriction constraints to the model. Xu et al [35] detailed the train formation process in high-speed railway stations and proposed a multiobjective programming model to minimize the train route cost and balance track allocation. Liao et al [36] integrated the TRP with the vehicle circulation problem, an integer programming model was proposed to maximize the overall transportation efficiency, and a Lagrangian relaxation algorithm was developed to solve the integrated model.…”

A multi-station high-speed railway hub is the interaction of multiple high-speed railway lines, and its operation determines the efficiency of the whole network. In this study, we focus on the train routing problem for a multi-station railway hub and propose a flexible scheme to improve the capacity utilization. Based on the flexible scheme, a mixed-integer programming node-arc model is formulated to minimize the total cost of train and passenger routes. Specifically, for diversifying the train routes, we consider the individual train rather than the train flow as the basic unit, which differs from the approach in previous studies. For each train route, in addition to the macro-scale route between stations, the micro-scale track allocation inside stations is also considered. Afterward, the optimization solver Gurobi is used to solve the model and obtain the optimization scheme. A case study based on real data from the Zhengzhou railway hub in China is implemented to evaluate the effectiveness of the optimization model. By comparing the optimization scheme with the fixed scheme and the sequential scheme, the results show our method could reduce the total cost by 29.35% and 22.58%, and the line and track capacity utilization of the optimization scheme is more reasonable. We provide some suggestions to help railway managers improve the operation efficiency and service quality of multi-station high-speed railway hubs.

The network operation of the subway can reduce the number of passenger transfers and improve subway operation efficiency. Based on the subway smart card data, this paper proposes an optimal design method for the cross-line operation scheme of subway trains. The method firstly calculates the OD matrix between subway stations, the passenger section flow, and the transfer flow according to the passenger smart card data. It then optimizes the design of the subway train cross-line operation plan, including determining the routing type of cross-line operation and the number of trains running. Finally, for the lines with cross-line operation conditions in the urban subway system, we design the cross-line operation schemes under all possible combinations. According to the volume of the cross-line passenger flow that the cross-line trains can carry, the top-ranked operation plans are preferably recommended. Taking the Chengdu subway network as an example, the research results show that, in the Chengdu subway network, the North Railway Station, Xibo City Station, and South Railway Station bear the highest transfer demand. The transfer demands that can be undertaken by cross-line trains are 23,934, 16,710, and 13,024 trips per hour, respectively. This shows that the proposed design method can accurately and reasonably screen out the transfer stations and lines with an urgent need for cross-line trains.

“…This aspect is critical for ensuring the safety of users, which number is increasing with an exponential law (Wijayanto, 2022). It is demonstrated that the decomposition processes of trains and stations can improve, for example, the occupancy balance of platform tracks and, consequently the safety of the total system (Xu, 2022). However, the consequence of an incident between a person and a train always has terrible consequences: suicide by train is a common case worldwide: victims place their bodies across the railroad tracks, leap in front of a moving train, or stand in front of it in order to be hit by it.…”

Rail transport has been changing the mobility of people. The Railway's development has pointed the focus on the safety management of trains and infrastructure, particularly related to passengers. This paper focuses on the methods adopted to guarantee high safety in railways; for this reason, it was interesting to present a literature analysis about this topic. The authors short-listed 48 articles for indepth analysis. Bibliometric research and a thorough literature assessment were conducted to evaluate the safety management in the Railway area. Today, the attention of experts and railway managers is very high on high-speed railways because of their high-risk levels. For this reason, many advanced technologies have been developing all over the World, thanks to the new artificial intelligence tools and machine learning, to guarantee a constantly high degree of safety. Especially the stations and specifically, the platform zones, are crucial hotspots for railway accidents, particularly suicide events. Some prevention techniques showed an increment in safety quality and made Railway the safest transport infrastructure. So, a resilient model applied to safety railways could improve even more substantial safety degree.
