I ended up getting a super deal on what turns out to be Flyer set 4904T, which is complete, save for missing the 639 box car (I can get one of those pretty readily) and the transformer has a dried out power cord. Engine and cars are in fantastic shape, the lot also came with some Plasticville buildings and a set of the remote switches. All for $75.00!
After cleaning and lubricating the 290 Pacific, she started running very well! I've always loved the "choo-choo" sound in AF trains! Hopefully the smoke unit will come back to life, too!
Anyway, should I check in Radio Shack or somewhere, what bulb is best to install in the 290?
Also, can a new power cord be put onto the transformer?
