Patent Images
1. A consist, comprising:
- a locomotive, having;
a frame;
a main engine mounted to the frame;
a plurality of wheels configured to support the frame and driven by the main engine;
a main generator driven by the main engine to generate a main supply of electric power; and
a first traction motor configured to receive the main supply of electric power and propel the locomotive; and
a tender car coupled with the locomotive, the tender car having;
a tank configured to store fuel;
an auxiliary engine;
a fuel delivery circuit connected to the tank, the auxiliary engine, and the main engine;
an auxiliary generator powered by the auxiliary engine to generate a supply of auxiliary electric power;
a second motor configured to receive the auxiliary electric power and propel the tender car; and
an energy storage system configured to store electric power generated by the second motor during dynamic braking,wherein the second motor is capable of propelling the tender car with stored electric power when the tender car is decoupled from the locomotive.
