This reminds me - has anyone built a fully functioning overhead rail electric
train layout where the power is provided by the overhead wires like this:
This would alleviate the need for powered rails and do away with the battery
issue. True, it would only work for prototypical electrified trains like
seen on the Northeast Corridor, but it would be neat to see if more people
could adapt the newer trains to this configuration. Too bad no freight
trains that I can think of use electric like this - it seems only passenger
trains use overhead wires?

Two-pole contact is needed. But most of the electrified railways use only one
overhead wire (like the ex-Soviet loco in the photo). The only examples of
more-wire systems I know about, are deep in the history:
--Siemens’ experimental high-speed train, 1903 (3-wire, 3-phase AC)
--Tabor-Bechyne railway in southern Bohemia, 1903 (2-wire, DC, for safety
reasons = lower voltage between wire and ground), 1930s rebuilt
to single wire
--some mountain railways in the Alps (2-wire, 3-phase???)
The freight/passenger question: I don’t know much about U.S. trains, but in
Europe there are electric locos that pull freight trains as well as passenger
trains.
