I couldn't agree more. In a locomotive, it's entirely appropriate to call the electric motor a transmission between the diesel engine and the wheels. And this is based on the fact there is only one power source, the DIESEL engine -- NO ELECTRIC STORAGE. They don't even regen on braking, they just dissipate the heat in resistor banks.
