متن کاملMonte Carlo train derailment model for risk assessment
A Monte Carlo train over-speed derailment model for risk assessment is developed based on the derailment coefficient (wheel lateral and vertical force ratio). The model considers a one lump train negotiating on curved tracks or tangent tracks. The derailment coefficients for these two situations are calculated and the probabilities of train derailment are obtained to enhance a large scale Monte...
متن کاملFreight-train derailment rates for railroad safety and risk analysis.
Derailments are the most common type of train accident in the United States. They cause damage to infrastructure, rolling stock and lading, disrupt service, and have the potential to cause casualties, and harm the environment. Train safety and risk analysis relies on accurate assessment of derailment likelihood. Derailment rate - the number of derailments normalized by traffic exposure - is a u...
متن کاملTrack geometry defect rectification based on track deterioration modelling and derailment risk assessment
Analysing track geometry defects is critical for safe and effective railway transportation. Rectifying the appropriate number, types and combinations of geo-defects can effectively reduce the probability of derailments. In this paper, we propose an analytical framework to assist geo-defect rectification decision making. Our major contributions lie in formulating and integrating the following th...
متن کاملTrain Schedule Optimization in Public
Attractive train schedules are quite important for the success of public rail transport. We consider schedules which are repeated after some xed time period. Periodicity is a well accepted, convenient attribute of all major railroad systems. Since trains share the public railroad network, we have to handle many connicting demands. Increasing competition from transportation alternatives as well ...
