Vintage Tyco HO #638 Chattanooga Steam Engine and Powered Tender. Both pieces are in nice, played with condition. May need a little dusting.

Tested and the tender motor worked. I did not have any fluid to test the smoke feature.

I don't know a lot about this style of HO train, but the 8 wheels on the locomotive only spin so far. A plastic piece in the center has a tab and it rotates so far until it hits a clear plastic piece in the center of the locomotive and then stops. Again, I don't know anything about this specific piece. Maybe that's the way they function.

But again, the motor in the tender does work.

Thanks for looking.
