Abstract: A fuel gas compression system includes a system which operates on direct current, a system which operates on alternating current and a system which is capable of operating on either direct current or alternating current. In the system that operates on either direct current or alternating current, a jumper is provided which is placed in the circuit when an alternating current is provided. When a direct current is provided, the jumper is removed from the circuit.

Abstract: A mounting assembly secures a generator and facilitates attachment to a railroad railcar on the end of the railcar axle. The generator produces electricity from the axle of a railroad railcar while it is traveling on a railroad track. A generator is mounted with a generator bracket and a backing plate to an existing bearing adapter on the railcar. A drive hub engages axle bolts on the railcar axle. As the railcar axle turns, the drive hub turns and with the drive hub connected to a generator the generator subsequently rotates to supply electricity to the railcar. Different types of generators can be attached with the mounting assembly to the railcar. The mounting assembly allows generators to be mounted without modification to the existing railcar structure.
