The cryogenic fuel supply system for an engine is arranged in locomotive two sections connected by an inter-section connection for the purpose of transferring fuel from one section to the other. There is a cryogenic reservoir for storage of a liquefied cryogenic fuel, a positive-displacement high-pressure cryogenic pump, an oil heat-exchanger, a gas heat-exchanger, a gas mixer, a gas receiver, a fuel filter, a controlled gas metering unit, pipelines, valves, controlled valves, and a control unit. The cryogenic fuel supply system further includes an intermediate buffer arranged between the cryogenic reservoir and the positive-displacement high-pressure pump and connected to the cryogenic reservoir by pipelines and to the positive-displacement high-pressure cryogenic pump by a pipeline and two additional pipelines. The additional pipeline is used both for discharging excess cryogenic fuel from the pump to the intermediate buffer and for maintaining a required pressure in the intermediate buffer and the cryogenic reservoir.
