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?

| Eric, I am considering buying stock in battery manufacturing. How about you? I have probably already spent a considerable sum of money on powering my Mindstorms robots. Maybe someone will design a butane based fuel cell that will work. Or perhaps a (...) (17 years ago, 2-Oct-07, to lugnet.trains)
