Abstract:
1. A coupling system for a train consist, comprising: a first conduit associated with a locomotive of the train consist; a second conduit associated with a tender car of the train consist; a fluid coupling connecting the first and second conduits; a first mechanical coupler associated with the locomotive; a second mechanical coupler associated with the tender car and configured to engage and lock with the first mechanical coupler; a locking device configured to inhibit disengagement of the first mechanical coupler and the second mechanical coupler, the locking device driven by fluid passing through the fluid coupling, wherein the fluid passing through the fluid coupling is fuel for the train consist; a pressure sensor configured to generate a signal indicative of the pressure of the fuel; an actuator configured to drive the locking device from an unlocked position to a locked position; and a controller configured to cause the actuator to drive the locking device based on the signal from the pressure sensor.
