BACKGROUND Little is known about train suicide and factors influencing its prevalence. This study tests the hypotheses that railway density, railway transportation volume, familiarity with railway transportation and population density contribute to train suicide. It also tests the relationship between train suicide and general population suicide and examines the prevalence and the characteristi...
The real-time Railway Traffic Management Problem (rtRTMP) is the problem of detecting and solving time-overlapping conflicting request done by multiple trains on same track resources. It typically consists in taking retiming, reordering or rerouting train actions such a way that propagation disturbances railway network minimized. rtRTMP an NP-Hard finding good strategy to simplifying its soluti...
In the 1980s/90s, a number of socio-acoustic surveys and laboratory studies on railway noise effects have observed less reported disturbance/interference with sleep at the same exposure level compared with other modes of transportation. This lower grade of disturbance has received the label "railway bonus", was implemented in noise legislation in a number of European countries and was applied i...
Railway crew scheduling problem is a substantial part of the railway transportation planning, which aims to find the optimal combination of the trip sequences (pairings), and assign them to the crew complements. In this problem, each trip must be covered by at least one pairing. The multiple-covered trips lead to impose useless transfers called “transitions”. In this study, a new ma...
DLR’s Vehicle System Dynamics group has a long tradition in the computational analysis of railway vehicles’ dynamics. The group’s main focus used to be on the development of software tools for the efficient analysis of general mechanical systems with a special emphasis on the dynamics of ground vehicles like automobiles, railway vehicles and aircraft landing gears. The respective research activ...
Railway timetabling is an important process in train service provision as it matches the transportation demand with the infrastructure capacity while customer satisfaction is also considered. It is a multi-objective optimisation problem, in which a feasible solution, rather than the optimal one, is usually taken in practice because of the time constraint. The quality of services may suffer as a...
This paper describes the system of medical hygiene and health care adopted by the Croatian section of Yugoslav Railways in the aftermath of World War Two until 1953, based on archival information. In 1945, the human resources section of the Railway Administration in Zagreb included the Department of Social Welfare with offices that managed health insurance in cases of illness and accidents, wor...
Efficiently coordinating the often large number of interdependent, timetabled train movements on a railway junction, while satisfying a number of operational requirements, is one of the most important problems faced by a railway company. The most critical variant of the problem arises on a daily basis at major railway junctions where disruptions to rail traffic make the planned schedule/routing...
The shield tunnel of the Kunming subway crosses beneath the Kun-Shi Railway. Due to the high requirements of railway track for settlement control, this article proposes the following technical measures for controlling the settlement based on the analysis of risks arising from the shield crossing railway: (1) Reinforcing the stratum of the region crossed by the shield in advance to achieve high ...
Global Navigation Satellite Systems (GNSS) are applicable to deliver train locations in real time. This train localization function should comply with railway functional safety standards; thus, the GNSS performance needs to be evaluated in consistent with railway EN 50126 standard [Reliability, Availability, Maintainability, and Safety (RAMS)]. This paper demonstrates the performance of the GNS...
