Abstract:Performance standards for Electronically Controlled Pneumatic (ECP) freight brake systems for use on the North American railroads are being developed by working groups composed of personnel from the railroad industry, the railroad supply industry, and AAR technical staff. Draft specifications (S-4200) have been developed covering system performance, head-end power, communications, connections, and cable. The performance specification is titled "Performance Requirements for Testing Electrically Controlled Pneumatic (ECP) Cable-Based Freight Brake Systems" and designated S-4200 (an equivalent process is under way to develop performance requirements for radio based ECP under S-4300). This specification is still under development, and a Failure Modes, Effects and Criticality Analysis (FMECA) remains to be made on the final version. Upon completion of this set of tests, it was determined that the TSM ECP brake equipment was suitable for installation on the FAST train.
