MANAGING A SUPPLY OF GASEOUS FUEL ON A TENDER CAR

摘要

A supply of gaseous fuel on a tender car for fuelling a locomotive engine requires the coordination of a variety of operational modes to improve the safety and efficiency 10 when operating components for delivering, refuelling, draining, capturing and storing gaseous fuel. A method and apparatus for managing a supply of gaseous on a tender car comprises receiving on the tender car a command signal from the locomotive commanding delivery of gaseous fuel from the tender car to the locomotive; transferring from the tender car at least one status signal to the locomotive indicating 1 status of the tender car; representing a plurality of operational modes of the tender car as a plurality of states; and transitioning between the plurality of states in response to the command signal and the at least one status signal.
