Abstract
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 tha…
