Abstract :
The Southeastern Pennsylvania Transportation Authority (SEPTA) is designing the modernization of the signal system on the Broad Street Subway, which runs north-south through the center of the City of Philadelphia. This project will replace the existing wayside and trip stop signal system with a continuous automatic train control (ATC) cab signal system, without wayside signals except at interlockings. The existing car fleet will be retrofitted, and a central control system will also be provided
