ABSTRACT:
The present hostler control of a computer control train brake system combines the computer control of the train and locomotive brake system with a manual control during a hostler mode to provide soft and safe operation of the vehicle. Interlocks provide efficient and safe transferring of the controls between the computer control brake system and the manual hostler control portion. The computer control train brake system includes an electropneumatic brake controller which automatically applies the independent brake once the hostler lead mode is determined. Next, the brake controller charges the brake pipe to release the train brakes. Control of the independent brake is transferred to a pneumatic independent brake control valve of the hostler stand after the brake pipe has been charged sufficiently to fully release the train brakes. The brake pipe is charged or the train brakes are released only after the independent brake application has reached a predetermined value. The computer controls the locomotive brakes in response to the pressure of the independent brake pipe and brake pipe. When the operator deactivates the hostler control, brake control is automatically transferred back to the computer control.
