An integrated locomotive braking and ECP braking control on a lead locomotive for implementing braking effort on all locomotives in a manner relative to braking effort applied on ECP freight cars. On the lead locomotive, a data interface can be established between an head-end-unit and a brake controller. The head-end-unit can electrically signal each ECP freight car to carry out braking commands. The integrated brake control can include a CPU, as part of either the brake controller or the head-end-unit, which can be programmed to provide braking effort on the lead locomotive relative to the braking effort applied on the ECP freight cars. The braking on the lead locomotive is implemented by the brake controller by controlling the independent brake relative to the braking effort commanded on the ECP freight cars. The independent brake on non-ECP trailing locomotives is connected to the lead locomotive independent brake via a standard independent brake pneumatic connection. As a result, the same braking effort applied on the lead locomotive via the independent brake is automatically implemented on the non-ECP trailing locomotives via the independent brake pneumatic connection such that all locomotives are braked relative to braking on the ECP freight cars.

A fixedly mountable event recorder for a railcar for monitoring performance of a brake system thereof includes (a) at least one port for receiving air from one or more brake system components; (b) at least one sensor for determining a pressure of the air received from the one or more brake system components; (c) a processor operative for analyzing the determined pressure to determine an operational condition of the brake system; and (d) an indicator configured to visually convey the operational condition of the brake system. The indicator includes a plurality of activatable visual indicia corresponding to a plurality of predefined operational condition status qualifiers associated with a corresponding plurality of predefined ranges of operational conditions. The predefined ranges of operational conditions are defined as a function of expected pressures associated with the respective one or more brake system components during corresponding operational conditions thereof.
