We used to have some monster diesel motors like those for back up power in the old Telephone exchanges where I worked. One of my jobs as an apprentice was doing test starts. That was always good fun.
This was in the days of electromechanical telephone exchanges and they drew a lot more power than the modern stuff. Just in the small city exchange I worked at had dual 48V DC power systems that were delivering 1500 to 2000 Amps each. Get some big event like an earthquake where everyone picks up the phone and you can watch the ammeters swing round and hit the stops.
