ASSESSMENT OF MASS TRANSIT TURN-BACK CAPACITY USING DYNAMIC SIMULATION MODELS

The line capacity of a mass transit railway is often governed by the frequency with which trains can be reversed at terminal stations and intermediate turnback sites. Factors that influence the maximum reversing capability include the fixed geometry of the track layout, the characteristics of the signaling and train control system, the performance of the rolling stock, the platform dwell times, and the requirements for crew changeover. In tendering a given signaling and train control system for a new or upgraded railway, the signaling contractor must be able to verify that the turnback headway specified by the railway administration is practicable. It also is necessary to have the means of both assessing quickly and demonstrating easily the effect on headway resulting from variations in design parameters. This paper reviews the principal factors that limit turnback capacity. It describes the application of simulation models that allow the operation of turnback sites to be assessed in detail using graphical animation.
