@puniko What's the deal with the power line on the left (not the one for the railroad, but one of the two ones above it)? It has four conductors (not counting the grounded one at the top). Is it one three-phase line with a spare conductor or what?
@robryk@puniko In industrial situations I've come across three phase wye busses (three phases plus a neutral and a separate ground) but I don't know if anyone ever distributes power like that on poles.
@shaunh Maybe? Generally you don't care about neutral if the line ends in a transformer (or multiple), because you can use a transformer that has inter-phase windings on input. @puniko
