Abstract: A method for fueling a rail system fuel tender which comprises a chassis and one or more fuel containers, with each fuel container adapted to contain a quantity of pressurized fuel, where the method comprises storing fuel at a fuel source storage facility located distant from the fuel tender, delivering fuel by a fuel delivery means from the fuel source storage facility to the fuel tender, and fueling the fuel tender by a fuel filling means.

Abstract: A system for fueling a rail system fuel tender which comprises a chassis and one or more fuel containers, with each fuel container adapted to contain a quantity of pressurized fuel, where the system comprises a fuel source storage facility located distant from the fuel tender, a fuel delivery means for conveying fuel from the fuel source storage facility to the fuel tender, and a fuel filling means for placing pressurized fuel into the fuel tender.

Abstract: An improved rail system fuel tender for use with one or more railroad locomotives capable of transporting a plurality of fuel containers suitable for containing pressurized fuel and suitable for directly fueling the one or more locomotives. The improved fuel tender may be powered by the locomotives to increase tractive effort, and the fuel containers may be separately fillable and separately removable from the fuel tender.
