A computer model, called Train Dispatching Simulation (TDS) has been developed to determine the capacity in terms of trains per day of a recently constructed 360-mile railway in the Middle East. The TDS model can handle both double and single track, CTC and ABS operations, and is able to examine, among other things, the operational and economic impacts of various train sizes and electrification versus diesel operation. A potentially significant phenomenon that became apparent in the model was that as the capacity of a given line is approached train delays increase rapidly and become asymptotic. Thus many actual railway lines may be closer to capacity than it appears. Methods of increasing line capacity are discussed.
