Well, HEP arrived in common use with the first, articulated streamliners, although it then gave way to a return to the individual car-mounted electrical system of axle-powered generator, batteries and switch panels, usually at 32V DC.

HEP didn't come along until 1970 or so with the U34CH engines and Comet coaches.  Electrical power on trains was largely provided by generators driven by the axles, charging banks of batteries under the cars.  Each car had its own power system.

MU was just that - multiple unit control of the engine.
