I recently bought my grandson a Lionel Remote train set that came with FasTrack and now realize a lot has changed since I was a kid. I started to expand the layout with more FasTrack and switches but became frustrated with the numerous dead spots on the track where the train would stop (tracks are on top of a carpet). I bought a bigger transformer and that didn't really help. So I tried to switch to tubular track that works great but realized I know way too little about the curves and switches. I first bought O-27 but the steam locomotive would not take the curves. The diesel I bought with smaller wheels and trucks worked OK. I then bought a complete track set (Lionel) that had all the required curves and cross-tracks. I think this set uses the 31 inch curve that is "standard"? My big question is: I am confused as to which O gauge tracks are compatible with each other; or do I have buy all one type (Lionel?). And when you talk about tinplate I have not idea if that is another factor that must be taken into consideration when buying track? I want to stay away from FasTrack because it is too expensive and sensitive to road surface conditions.
Thanks
