Abstract

Train pathing is concerned with assigning trains and train times for a set of rail links, station stops, etc., so as to meet a system of constraints on headways, trip times, dwell times, etc. while minimizing delays or costs and meeting travel demands. In a previous paper the authors presented a model, algorithms, and strategy for pathing trains in one direction. Here they extend this to more general more complex rail networks, with choice of lines, station platforms, etc., as is more typical of the high density scheduled passenger railways in Britain and Europe. The authors apply the model to a small network and find acceptable solution times. Applying additional search strategies from the previous paper should reduce solution times by further orders of magnitude.
