摘要： 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.

摘要： A locomotive air brake control system that responds to penalty braking requests from external systems by applying a varying amount of train brake level based on monitored and calculated parameters in order to enforce a defined train condition. The system may include a minimum acceptable train braking, a condition to be achieved to prevent further application of train brakes, and a maximum train brake level to be applied in response to the request. Alternatively, the system may apply braking in stepped levels according defined thresholds for a train behavior variable of interest such as speed or deceleration. The system may be configured to incrementally apply and release train brakes during the adaptive penalty, and may also adjust the level of braking according to calculated braking capacity of the train.
