OVER-THE-ROAD SIMULATION MODEL

The MoPac O-T-R computer program has been modified to include variable turnout and train separation time so that dark, ABS, or CTC territory can be studied. Also the meet resolution logic has been modified to allow the delayed train to hold the main track, while the oposing train is rerouted through the siding when this solution will minimize total delay. A calcomp plot routine has also been added as an alternative to the MoPac high-speed printer plot. Refer to the Missouri Pacific Railroad's description of its over-the-road model for more detail on the program. The Southern has used the model successfully to evaluate siding and/or Double Track changes in dark, ABS and CTC territories, to evaluate proposed line relocations and potential CTC projects. The model has also been used to project line capacity.
