This report, prepared by the Transportation Technology Center, Inc. (TTCI), Pueblo, Colorado, a subsidiary of the Association of American Railroads (AAR), summarizes the findings of the service testing of electronically controlled pneumatic (ECP) brakes, carried out between the spring of 1996 and the summer of 1997. The report focuses on the Conrail Revenue Service Test, which is one of the two tests specifically featured in Task Order Number 1 - Advanced Braking System Safety Evaluation. In addition, selected results from the other revenue service tests, conducted during the same time, are included for comparison purposes. Also, the actions taken by the AAR in the specification development process, as a result of the findings of the revenue tests, are discussed. The primary focus of AAR's ongoing work is to establish a non-overlay ECP test train, assure that the system is safe for revenue service, and then compare its operation to an identical standard train. Once a pure ECP test train is established, it will not be capable of operating in a conventional mode, and the data from such a test will be a true indication of the economic benefits possible through the use of ECP brake system.
One of the major barriers to implementation of Electronically Controlled Pneumatic (ECP) brake technology is a freight car’s interchange requirement...
