Guess those miles and miles long freight train hauling/towing rail cars are 'not' hybrids ????
They are not hybrids. They are diesel electric locomotives. They have no batteries so they won't move unless the engine is running. The electric aspect is for the transmission of power; it has nothing to do with battery power, regenerative braking, or emissions reduction as typical hybrid automobiles do..
They do use the use the electric motors for braking though. Reverse the current flow and use them as generators. But then just burn off the generated electricity in monster resistor packs.
Surprising they haven't yet gone to monster batteries instead of resistor packs. Maybe the weight is prohibitive?
