9. An auxiliary engine warming system for a primary engine in a diesel locomotive comprising:
-
a modular engine assembly including an auxiliary diesel engine and a generator mounted to a plate, the assembly removable as a unit from a frame for the engine warming system via a slidable engagement between the plate and the frame and the plate detachably connected to the frame with a plurality of threaded fasteners; an auxiliary fuel tank including a fuel line detachably connected to the auxiliary engine and including a first fitting detachably connectable to a first fuel line for a fuel tank for the diesel; a coolant heater with a second fitting detachably connectable to a second fuel line for the fuel tank for the diesel; a coolant temperature sensor interfacable with a cooling system for the diesel locomotive; an oil temperature sensor interfacable with an oil system for the diesel locomotive; a controller arranged to receive signals from the coolant and oil sensors; and
,an emergency dialer arranged to receive signals from the controller and to automatically dial a preprogrammed number to transmit an alert message in response to an alarm signal from the coolant sensor or the oil sensor, wherein the first and second fittings are the only fittings in the system used to supply fuel to the system.

10. An auxiliary engine warming system for a primary engine in a diesel locomotive comprising:
-
an auxiliary diesel engine; an electrical generator mechanically coupled to an output of the auxiliary engine; a temperature sensor operatively arranged to measure a temperature of a coolant in the primary engine of the locomotive; an emergency dialer for automatically dialing a preprogrammed number and transmitting an alert message when the temperature sensor measures a temperature below a minimum limit temperature of the coolant; a mounting plate, wherein the auxiliary engine is secured to the mounting plate, wherein the mounting plate is operatively arranged to slidingly engage with at least one slot in a frame of the auxiliary engine warming system; a vibration dampening means for reducing a transmission of vibrations from the auxiliary engine to the locomotive; an auxiliary fuel tank arranged between a primary fuel tank of the locomotive and the auxiliary engine; a coolant pump for pumping the coolant from the primary engine through the coolant heater, and a coolant heater for warming the coolant as the coolant is pumped through the coolant heater and back into the primary engine; and
,an oil pump for circulating oil in an oil sump of the primary engine through the primary engine.
