Scott, TW and Joe,

Scott, do you work with any of the electric lines for overhead trains? If so, what is the volatge they use? I almost got a job on the railroad with my dad as a high voltage electrician. I went into res./com. electrical work instead. Also weren't they changing the signals for the whole country? A friend of mine is a conductor on the "Susie Q" line here in NJ. Their signals changed from the ones I knew on the E-L lie that my dad worked for.
TW, You don't have anything to do with high voltage with the strasburg rails do you? I have been to PA and seen/riden the old steam line. ( Of course I love the old steam. I just wish I liked it many years ago when I was a youngster.)
Joe, Does this have to do anything with subways or elevated railways?
