When I dug the trains out of my grandparents' basement a year back, there were two sets; one was an early low-end Flyer passenger set headed by a 1096 electric-profile motor that had belonged to my grandfather, the other a nice steam freight set headed by a 3326 2-4-2 steam loco that had belonged to my uncle. My father's set, a Hoge 900 streamliner set, he had found some thirty years ago, taken home, then given away.
It's always a disaster to find trains in a musty old basement, and this held pretty true to form for these. Perhaps because of the way they had been packed, the low-end set survived in relatively good shape, but the freight set is pretty rough, especially the 3326. It's a shambles:

It actually photographs a lot better than it is

. The wheels are swollen and crumbling, and there's no turn in the motor. I haven't tried disassembly yet, but I suspect it will fall to pieces in my hands. I was thinking I'd just gut it for parts, then move on, but now I don't think I could stomach that, so I'll be looking to do a restore. Certainly all the wheels will need to be replaced, and maybe a good bit of the motor and e-unit. The boiler seems good, along with all of the trim. Last time up to York, a Flyer mate had a bin full of reconditioned motors, so maybe I'll just try that first. I don't think these are that uncommon, but the pilot and trailing truck may be (both of which are riveted onto the motor frame).
This looks tough, but do-able...we'll see.
