Communications Based Train Control (CBTC) System Upgrades

P1-30

Philadelphia County

Engineering/Design Firm: SEPTA

This project upgrades and replaces computer hardware and software for the CBTC system in the 5-mile long Trolley Tunnel through University City & Center City. The project goal is to increase signal system reliability and improve capacity in the Trolley tunnel, enhancing the 10 year old system.

CBTC blends state-of-the-art safety features with efficient computer controlled movements of Trolley cars through radio based Positive Train Control (PTC). The system design enforces a safe traveling distance between two trolleys, prevents trolleys from exceeding speed limits and allows multiple trolleys to platform at stations under strict speed enforcement.

The system handles about 30 SEPTA trolleys per hour operating in the tunnel, with the potential to safety control and separate up to 75 trolleys simultaneously. CBTC provides a level of protection exceeding the new Positive Train Control standards recently developed by the Federal Railroad Administration.
