ABSTRACT: This letter report, prepared by the Association of American Railroads (AAR), Transportation Technology Center (TTC), Pueblo, Colorado, covers the final report on the Conrail Electronically Controlled Pneumatic (ECP) Brake Revenue Service Test. The test report written by Conrail is attached. The Conrail revenue service ECP brake test was intended to investigate the possible benefits of ECP brakes. Mechanical repairs and energy consumption were tracked on the ECP train and on a nearly identical train in the same services (this train is referred to as the "placebo" train in the Conrail report). This report will also include the latest information on the ongoing Burlington Northern Santa Fe (BNSF) revenue service testing. The Conrail report covers five major areas: (1) energy consumption and coupler force data, (2) car control device (CCD) reliability, (3) percentage of operability under ECP brake control, (4) stuck brakes in the overlay mode, and (5) repair data. This letter report will address each of these areas.
