Abstract: Reliability of a railway timetable depends upon section capacity and slack allowed for handling small uncertainities in railway operations. Section headway depends upon factors like train dynamics, types and location of signals, platform allocations at terminals, traffic pattern and rake linking. Slack is given in timetable in form of headway slack, traversal time slack, gaps in timetable and turnaround times. We present impact analysis of these factors with the help of simulation on real data from Western Railways. We present cases in which we show how certain railway practices lead to secondary delays. Finally, we highlight the possibilities of OR in making more efficient timetables.
