The best track in my opinion is Gargraves track with Ross switches. Get stainless steel if you need to be concerned with moisture. If I was going to do my layout over I would use only Gargraves track and Ross switches.
Lionel Fastrack tarnishes too quickly and has electrical issues, and the switches are a few dollars more then Ross Custom switches.
Also track with built-in roadbed has diameter limitations, especially Fastrack! MTH's Realtrax and Scaletrax are duds with the switches.
