Abstract

Assessment of mass transit turn-back capacity using dynamic simulation models DC Gill Projects Delivery Department, Westinghouse Signals Limited, UK Abstract 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 turn-back sites. Factors that influence the maximum reversing capability include the fixed geometry of the track layout, the characteristics of the signalling and train control system, the performance of the rolling stock, the platform dwell times, and the requirements for crew-changeover. In tendering a given signalling and train control system for a new or upgraded railway, the signalling contractor must be able to verify that the turn- back headway specified by the railway administration is practicable. It is also necessary to have the means of both assessing quickly and demonstrating easily the effect on headway resulting from variations in design parameters.
