The enhancement of the Carnegie Mellon software package to incorporate fixed and moving-block signaling schemes is described. The train performance simulator (TPS) component of the module calculates the train dynamics for each train set in the simulation. For fixed-block signaling systems, the TPS monitors the preceding signal for each train and bases the train's calculations on that particular aspect, the type of signal, and whether a crossover is in the next block. Essentially, the aspects determine the local speed restrictions for each train. The aspects themselves are linked together, providing three and four block protection. Conversely, moving-block signaling systems would have train calculations based on the preceding train's dynamics, as opposed to fixed locations along the track. The TPS becomes interactive if signaling is invoked. A communications window is displayed at the bottom of the screen indicating the next aspect which the train is approaching.
