Sorta new to model railroading and TOTALLY new to 2 rail. To venture in I picked up two 2-rail DC Atlas F7 units for what I thought was a good deal ($125 for two units). Save for the motor, screws and wheels, the entire thing is plastic - frame, gears, shafts, etc., and the body simply snaps on (no screws). Very surprising really. Seller didn't hide anything it's just in my exposure to postwar and MPC era Lionel, I've never seen anything like this. But hey, at least they're in great shape . I do have two questions:
1.) Are they worth anything? I like tinkering with the stuff I buy, esp. adding more pulling capacity, but these will not survive any sort tinkering. If they're not worth anything I'll probably just flip 'em.
2.) Does anyone have a link or a summary history of these? The boxes don't have dates. Was this a starter train? Was Atlas once upon a time only at the very low end of O scale? What years were these made?
2.) One unit has a bad motor (shorted windings, which the seller disclosed) but I can't find a replacement. The major hitch is shaft diameter which needs to interface to the existing prop shafts. Specs are 1.285" OD, 2.00" L, 0.078" shaft OD, dual shafts. Any ideas where to get one? I've checked eBay, Amazon, etc.
