1. A consist power system, comprising:
- a main engine located onboard a locomotive of a consist;
a main generator driven by the main engine to produce a main supply of electric power;
a traction motor configured to receive the main supply of electric power and propel the locomotive;
an auxiliary engine located onboard a tender car towed by the locomotive;
an auxiliary generator driven by the auxiliary engine to generate an auxiliary supply of power directed to the locomotive; and
a switch mounted on the locomotive, the switch being configured to operate alternatively between three options of;
connecting the main generator to both the traction motor and an auxiliary load on the locomotive,connecting the main generator to only the traction motor, andconnecting the main generator to only the auxiliary load on the locomotive.
