I have been out of the train layout building for over 20 years. My trains are crying in my attic for me to set up a new layout. A lot of new track types are now available. I am looking for the pros / cons for the different new track styles like; Lionel Fast track, MTH RealTrax, Atlas Track, etc. In the past, I have had a lot of issues with the traditional Lionel O and O27 track with pins not connecting , rusting, and current dropping over the layout.
