AUTOMATIC BLOCK SIGNAL SPACING

Computer program uses the AAR TTD train operations simulator (TOS) to evaluate the spacing of each pair of signals on its signalled lines. For each pair of signals, the timetable tonnage and maximum authorized speed is determined for each approach signal, and the model determines if a full service application of the automatic brake will stop the train short of the next signal. This is a high volume production use of one of Track/Train Dynamics models. The Southern, in addition to evaluating the spacing of all its existing signals, has studied all new proposed signal installations. An interface was developed between the model and the Southern's computerized track characteristics master file to facilitate the high volume profile needs of this application.
