Abstract

A system that allows an electronically controlled pneumatic (ECP) railcar to be optionally selected as the ECP End of Train (EOT) device when that car is positioned at the end of a train regardless of its physical orientation. This eliminates the requirement to use and install a traditional End of Train (EOT) device at the end of an ECP train while maintaining the same train integrity monitoring functionality that is typically provided for train brake-in-two detection and closed cut-out cock detection. The system also eliminates the requirement for a dedicated EOT device at the end of the train for ECP “RUN” Mode operation, and allows any ECP car to function normally as part of the train or act as the EOT device when selected.
