Abstract
A system provides dual power producing capability to a diesel locomotive. The diesel engine drives the power generating system on the locomotive when the locomotive is operating under normal conditions. An inverter is provided to drive the power generating system on the locomotive and for supplying auxiliary and head end power when the locomotive is operating on third rail power and the engine is de-energized.
Claims11
An electrical system for providing dual power producing capability to a locomotive having a power generating system including a main alternator, the electrical system comprising:
- (a) an engine for driving the power generating system of the locomotive when operating under normal conditions;
- and
- (b) conversion means for driving the power generating system of the locomotive when operating on third rail power.
A method of providing dual power producing capability to an engine-driven locomotive having a power generating system including a main alternator, the method comprising the steps of:
- (a) driving the power generating system of the locomotive from said engine when operating under normal conditions;
- and
- (b) causing the main alternator to drive the power generating system of the locomotive when operating on third rail power with the engine shut down.
An electrical system for providing uninterrupted transfer of power to a locomotive from an engine power source to a third rail power source, the locomotive having a power generating system, the electrical system comprising:
- a main alternator;
- an inverter for causing the main alternator to drive the power generating system of the locomotive when operating on the third rail power source;
- and
- means for powering up the inverter and simultaneously powering down the engine power source.
