Energy absorption design for crash energy management passenger trains based on scaled model
To improve the passive safety protection of crash energy management (CEM) passenger train, this paper presents the energy absorption design study for CEM passenger trains based on a 1/8th-scale model. By analysing the similarity of thin-walled structures for CEM trains, the similitude ratios of physical parameters were obtained and used to design the scaled train model. The dynamic responses of scaled train were analysed through finite element simulation and collision test. Compared to the test results, the errors of dynamic responses in simulation were within 1.79%, indicating that the finite element model of scaled train was accurate and can be used to study the energy absorption characteristics of CEM passenger trains. To improve the crashworthiness of CEM passenger trains, selecting six key parameters affecting energy absorption of head car and middle car as design variables, and taking the maximum energy absorption of head car and the minimum standard deviation of energy absorption for middle cars as targets, a multi-objective optimization was carried out to gain the optimal solution of key energy absorption parameters. Optimization results indicated that the energy absorption of head car has been increased by 195.20%, and the standard deviation of the energy absorption of middle cars has been decreased by 81.06%.

Amtrak, America's Railroad
Discover the story of Amtrak, America's Railroad, 50
years in the making .
In 1971, in an effort to rescue essential freight
railroads, the US government founded Amtrak. In the post-World War
II era, aviation and highway development had become the focus of
government policy in America. As rail passenger services declined
in number and in quality, they were simultaneously driving many
railroads toward bankruptcy. Amtrak was intended to be the
solution.
In Amtrak, America's Railroad: Transportation's Orphan and
Its Struggle for Survival , Geoffrey H. Doughty, Jeffrey T.
Darbee, and Eugene E. Harmon explore the fascinating history of
this popular institution and tell a tale of a company hindered by
its flawed origin and uneven quality of leadership, subjected to
political gamesmanship and favoritism, and mired in a perpetual
philosophical debate about whether it is a business or a public
service. Featuring interviews with former Amtrak presidents, the
authors examine the current problems and issues facing Amtrak and
their proposed solutions.
Created in the absence of a comprehensive national
transportation policy, Amtrak manages to survive despite inherent
flaws due to the public's persistent loyalty. Amtrak, America's
Railroad is essential reading for those who hope to see
another fifty years of America's railroad passenger service,
whether they be patrons, commuters, legislators, regulators, and
anyone interested in railroads and transportation history.

Optimization of Passenger Train Line Planning Adjustments Based on Minimizing Systematic Costs
Optimizing passenger train line planning is a complex task that involves balancing operational costs and passenger service quality. This study investigates the adjustment and optimization of train line plans to better align with passenger demand and operational constraints, while minimizing systematic costs. These costs include train operation expenses (e.g., line usage fees and station service fees), passenger travel costs, and hidden costs such as imbalances in station stops. Line usage fees refer to charges for using railway tracks, whereas station service fees cover services provided at train stations. The optimization process employs a Simulated Annealing Algorithm to adjust train compositions, capacity configurations, and stop patterns to better match passenger demand. The results indicate a 13.89% reduction in the objective function value, reflecting improved overall efficiency. Notably, most costs are reduced, including train operating costs and passenger travel costs. However, ticketing service fees—which are calculated as a percentage of passenger fare revenue—increased slightly due to additional backtracking in passenger travel paths, which raised the total fare collected. Overall, the optimization improves the operational performance of the train network, enhancing both efficiency and service quality.

Coupling analysis of passenger and train flows for a large-scale urban rail transit system
Coupling analysis of passenger and train flows is an important approach in evaluating and optimizing the operation efficiency of large-scale urban rail transit (URT) systems. This study proposes a passenger-train interaction simulation approach to determine the coupling relationship between passenger and train flows. On the bases of time-varying origin-destination demand, train timetable, and network topology, the proposed approach can restore passenger behaviors in URT systems. Upstream priority, queuing process with first-in-first-serve principle, and capacity constraints are considered in the proposed simulation mechanism. This approach can also obtain each passenger's complete travel chain, which can be used to analyze (including but not limited to) various indicators discussed in this research to effectively support train schedule optimization and capacity evaluation for urban rail managers. Lastly, the proposed model and its potential application are demonstrated via numerical experiments using real-world data from the Beijing URT system (i.e., rail network with the world's highest passenger ridership).

QoS based deliver model of the packages transportation by the passenger train and solution algorithm
In recent years, statistics show that the percentage of household consumption in GDP is getting higher and higher. One of the subsequent influences is that the transport demand for packages has increased sharply. Hence it is very necessary to propose diverse transport organization modes in accordance with the different situation in different countries. A kind of new transportation mode,

train pickup and delivery problem with time window
(MPMT-PDPTW) is proposed in this paper. It aims to achieve express package transportation with minimum cost and maximize utilization of luggage car of a passenger train at the same time. Considering the multiple constraints, such as limited carrying capacity, fixed departing and accepting time, we define the
quality of service
(QoS) as the evaluation criteria for package express transportation by the passenger train. A kind of meta-heuristic algorithm,
greedy randomized adaptive search procedure
(GRASP), is designed to make full use of the redundant capacity of railway luggage car. An example is designed according to the railway passenger train timetable released by
China Railway Corporation
(CRC), the assignment schemes of packages at different railway stations reveal that the new transportation mode proposed in this paper is feasible and practical in package express transportation, and also has advantages in speed comparing with the highway and in transport cost over the airline.

Comparative characteristics of the emissions control during the operation of passenger trains
The trend in the development of railway transport also includes the solution of such an important environmental, technological, sanitary and, to some extent, aesthetic problem as the transfer of all operated mainline passenger trains to environmentally friendly toilet complexes (EFTC). For the disposal of EFTC waste, a system has been created for the disposal of fecal waste in parking lots, which are then transported by sewage disposal machines and dumped into general treatment facilities. At the moment, as one of the possible options for industrial waste disposal of EFTC, wastewater sludge incineration plants are being considered. The method of waste incineration reduces the time, labor and financial costs of waste turnover, and taking into account the epidemiological risks of fecal waste, it has high development prospects. This article discusses similar combustion processes using the example of technologies implemented at wastewater sludge incineration plants, emissions from enterprises and the processes of formation of pollutants. And also, within the framework of this work, a comparative analysis of the control of emissions of pollutants from the combustion of sewage sludge into the atmosphere in the Russian Federation and in the EU, countries were carried out.
