Heres A Dumb Question

I went into Hobby Lobby today and saw a train set that I would be intrested in buying. I have several Lionel trains already. My question is will an Atlas O set run on my LIonel Fastrack with no problems?

Thanks in advance. Greg

To the best of my understanding there shouldn’t be any problem.

No problems as long as the Atlas set minimum curve requirements are met by your existing track.
