Got a FREE American Flyer 3 rail train set tonight, at railroad club meeting. In fairly rough shape, but not too severe! Needs a bit of help, wheels in particular. I know AF made 2 rail stuff, and Standard Gauge stuff in the 1920's/30's. I'm not aware that they made a Lionel size 3 rail train! I have a bullet nose 4-6-2, tender, White AF boxcar, Shell tank and Caboose. Locomotive, in general. Head on, showing a B&O Capital logo. Any information about it, is much appreciated. In addition, to whatever I'm able to come up with! Thanks!!
