Abstract
A railroad traffic control system that links each locomotive to a control center for communicating data and control signals. Using on-board computers, GPS and two-way communication hardware, rolling stock continuously communicate position, vital sign data, and other information for recording in a data base and for integration in a comprehensive computerized control system. The data base includes train schedules for real time display on train monitors. The current position of each train is compared to its planned schedule online to provide immediate information to the dispatcher to determine whether a corrective action is necessary. When a train's deviation from its planned schedule exceeds a predetermined parameter, the system automatically calculates alternative schedules for all trains in the system according to preselected operational constraints as necessary to minimize the effect of the deviation.
