Abstract

Multi-train simulation: verification and accuracy William A M Barter Comreco Rail Ltd., York, England Abstract Many simulation packages model the movement of individual trains, to establish the speed profile, or support timetable planning. Some extend the potential of simulation to model multi-train operations by adding data on the network infrastructure. Extra functionality is achieved by increasing the range of input factors. A single train simulator will match train mass with tractive effort to calculate train acceleration. Multi-train simulation needs detail of signal section lengths, the track layout and locations of critical track circuits. Validity is improved by further additional input factors, such as gradients, train resistance, transmission efficiency, equipment and driver reaction times, and specific signalling rules. However, comprehensiveness brings difficulties. A package capable of detailed simulation will be complex and data-hungry
