In the event of a collision between a traveling, high speed train and a vehicle, the scale of human fatality and property damage can increase substantially if the train derails from its track after impact. Hence, it is important to identify the conditions and factors that may potentially lead to derailment in the event of a train-vehicle collision incident at a highway rail grade crossing. This...

OBJECTIVE To analyze the status of occupational stress in different types of train drivers. METHODS By using cluster sampling method, a cross-sectional study was conducted in 1 339 train drivers (including 289 passenger train drivers, 637 freight trains drivers, 339 passenger shunting train drivers, and 74 high speed rail drivers) from a Railway Bureau depot. The survey included individual fa...

The evaluation and control of the trains induced vibrations needs even more attention in the case of underground tracks which passes near to monuments and historical sites. The rail corrugations which occur due to the wheels’ impulse loads during the operation period of underground railway tracks, usually amplify the ground borne noise and vibration. In the current study, the mentioned phenomen...

Real-time train dispatching (i.e., rescheduling and replatforming) in passenger railway stations is a very important challenging task. In most major stations, this task carried out by hand highly trained dispatchers who use their extensive experience to find near-optimal solutions under conditions. With several simultaneous deviations from the timetable, however, traffic situation may become to...

Train passenger door is the key system for operation and maintenance on urban rail train. In this paper, we analysis passenger door system of urban rail train working process and establish the mathematical model. Firstly, we use the method of parameter estimation to get physical parameters of doors on different working condition. Then fault diagnosis experiment is done to train passenger door w...

The train plan of urban rail transit under multi-routing mode can be divided into three parts: train formation, train operation periods and corresponding train counts of each routing in each period. Based on the analysis of passenger’s general travel expenses and operator’s benefits, the constraints and objective functions are defined and the multiobjective optimization model for the train plan...

Urban rail transit systems are rapidly developing around the world. Due to a great deal of urban traffic pressure, improving the efficiency and capacity of urban rail transit systems is an increasing demand. Because it is a key subsystem of urban rail transit systems, communication-based train control(CBTC) is an automated train control system that makes use of train–ground wireless communicati...

Title of Document: MULTI-CARRIER TRACK CAPACITY ALLOCATION IN FORWARD AND SPOT MARKETS OF FREIGHT TRANSPORT April Yi-Wen Kuo, Doctor of Philosophy, 2008 Directed By: Associate Professor, Elise Miller-Hooks, Department of Civil and Environmental Engineering This dissertation addresses multi-carrier, multi-line train scheduling problems for forward and spot markets. Schedules resulting from solut...

This article presents a novel genetic algorithm designed for the solution of the Crew Scheduling Problem (CSP) in the rail-freight industry. CSP is the task of assigning drivers to a sequence of train trips while ensuring that no driver’s schedule exceeds the permitted working hours, that each driver starts and finishes their day’s work at the same location, and that no train routes are left wi...
