Recent collaboration between AAR, railroads, and ECP suppliers highlights performance specification for ECP brakes.
The AAR has been developing testing requirements for Electronically Controlled Pneumatic freight brake systems (ECP brakes). This effort began in the Fall of 1993 with a series of town meetings between the railroads and potential suppliers of ECP brake systems. The ECP project is now at the beginning of a revenue service testing phase with the cooperation of the railroads, the FRA and ECP suppliers. The ultimate goal of the AAR is to produce a performance specification for electronically controlled pneumatic freight brake systems so that any car with ECP equipment from any manufacturer can operate together in the same train. This paper will describe the latest developments of the AARs ECP concept.
