"Note the double-pantograph on the roof." I am not an electrician, but is that because both sides of the circuit are in the overhead? How does that work? Thanks.

I'm also not an electrician; I'm just an amateur photographer. I read somewhere: The Gornergratbahn is using three-phase electric power. This requires two overhead conductors, with the track forming the third conductor
