Abstract: 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.

Abstract: Various methods and systems are provided for modifying a fuel volume of a fuel container based on fuel consumption. In one embodiment, a method comprises storing an initial fuel volume measurement for a fuel container of a first rail vehicle and modifying the initial fuel volume measurement based on fuel consumption of an engine of a second rail vehicle to determine a modified fuel volume.

Abstract: Various methods and systems are provided for initiating and executing a fuel routine for a vehicle. In one embodiment, a method comprises sending from a controller of a vehicle a fuel request to a fuel tender to reduce a pressure of gaseous fuel on the fuel tender and adjusting one or more vehicle operating parameters to allow consumption of the gaseous fuel at an engine of the vehicle when the pressure of the gaseous fuel is below a threshold supply pressure.
