I just bought a box of mixed trains at a yard sale - American Flyer set and has some 3 rail Lionel (I think) and it has 20-30 pieces of a cardboard backed 4 rail track that I am not familiar with. It has the 3 rails standard on AC Lionel - Marx track but has a 4th rail that is lower than the rest of the three (all tubular). Since I'm not a big Flyer person my guess this is Flyer??? I can post a picture here if need be. Would appreciate some help in iding this track.
Thanks much!
