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, refueling, 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.

A method of reducing vapor generation in an LNG fueled vehicle is provided. The LNG fueled vehicle includes an LNG fuel system including an external LNG pump. The method includes a step of predicting if the LNG fueled vehicle will be operated during a first forthcoming time period using a controller. If the LNG fueled vehicle will be operated during the first forthcoming time period, as determined by the first predicting step, the method includes cooling the external LNG pump.

A tank system includes an extraction device and a tank. The extraction device has an extraction line and an attachment device. The tank includes a tank top side having a fastening wall and a first tank top side section. The fastening wall and the first tank top side section delimit a tank interior space at the top side. The tank interior space can be filled with an exhaust-gas after-treatment liquid, the fastening wall is disposed obliquely to the first tank top side section, the fastening wall has a fastening surface and a tank opening, the attachment device is fastened to the fastening surface, and the extraction line is guided through the tank opening. A vehicle having the tank system is also provided.

A dual-fuel tank houses one or more compressed natural gas (CNG) vessels and one or more diesel fuel vessels. The diesel fuel vessels are generally disposed laterally outwardly from the CNG vessels to provide a buffer that protects the CNG vessels from side impacts. The dual-fuel tank may be retrofit onto a diesel locomotive in place of the locomotive's diesel fuel tank to convert the locomotive into a dual-fuel locomotive. The dual-fuel tank may be provided in a ship.
