PHW Announces Its Largest Ever Contract Award

Sub-contract is to install vital, microprocessor-based, PTC system onboard all SEPTA's transit rail vehicles
Aug. 30, 2012

Invensys Rail Corp. announced that its PHW subsidiary has been awarded a sub-contract to install a vital, microprocessor-based, PTC system onboard all of SEPTA's transit rail vehicles. The SEPTA PTC system will be based on the ACSES II system. PHW's onboard ACSES OBC will be combined with PHW's 9-Aspect ATC equipment which will replace the existing Cab Signal System (CSS) installed on SEPTA rail vehicles. The onboard PTC system will communicate with wayside locations via track circuits, track-mounted transponders and an onboard, 220 MHz radio system. A new Aspect Display Unit will be provided that will display both PTC and cab signal information to the train engineer.
