Various methods and systems are provided for initiating and executing a fuel routine for reducing a pressure of gaseous fuel in a gaseous fuel system for a vehicle. In one embodiment, a control system for a vehicle comprises a controller operable to: determine a required pressure relief event is needed for a fuel tank on a fuel tender coupled to a first vehicle; and communicate a request to reduce a pressure of a gaseous component disposed within the fuel tank or adjust operation of a first engine on board the first vehicle to consume the gaseous component.

A fuel supply system for mounting to an undercarriage of a locomotive includes a first enclosure and a second enclosure that are disposed below the undercarriage of the locomotive. The first enclosure is configured to extend partway along a length of the undercarriage and is designated to store a first type of fuel therein. The second enclosure is located adjacent to the first enclosure and configured to extend parallelly with respect to the undercarriage. The second enclosure is designated for enclosing components that are configured for supplying a second type of fuel to an engine of the locomotive.

A vehicle system comprises an interface assembly and a controller both on board a first rail vehicle. The interface assembly comprises one or more mechanical couplers, fuel couplers, fluid couplers, and electrical connectors, to detachably couple the first rail vehicle to a separate, adjacent fuel tender vehicle, for the transfer of one or more of fuel (e.g., compressed natural gas) from the fuel tender vehicle to the first rail vehicle, heated fluid from the first rail vehicle to the fuel tender vehicle (e.g., for regasification of liquid natural gas stored in the fuel tender vehicle to the compressed natural gas), or electrical power and/or control signals between the first rail vehicle and the fuel tender vehicle. The controller is configured to at least partially control operations of the first rail vehicle in relation to interfacing with the fuel tender vehicle for fuel transfer, heated fluid transfer, etc.

A frangible closure coupling is used with or on pipe of a tank that contains a potentially dangerous fluid, such as liquid natural gas. The closure coupling mitigates the uncontrolled release of fluid from the tank in the event of a rupture of a pipe attached to the tank.
