Went to bed. Woke up. That can't be right, running those trains on 25000vac single phase. Searched the net, sure enough, the locomotives are running on 3 phase synchronous motors. But 25000v will arc 10" at least in the dry, not enough room for 3 wires across the track with allowance for rain surely? Photos of track not clear- can they be carrying converters on board?
