The South Eastern Pennsylvania Transport Authorities (SEPTA) awarded Bombardier Transportation a contract for the in-house design, installation support and commissioning of a CITYFLO 650 solution for the loop under the city.
The CITYFLO 650 solution supplied includes the EBI Com radio block centre, EBI Cab ATC onboard equipment and the EBI Screen 1500 control room. The CITYFLO 650 solution was chosen as the cab-signalling system can be adapted to manually operated vehicles running in mixed traffic and in a transit tunnel.
In total, the line is 8 km long with 115 trolley cars, equipped with CITYFLO 650 ATP, running between the 6 stations. The SEPTA system is the first application of CITYFLO 650 technology employed on a steel wheel/steel rail system.
