And I have been for several months now. Lee Willis' thread about his layout this morning has me seriously thinking about it now. I am currently into 2R with a small switching type layout. I am not really and never will be an operator. I like to run my trains, turn them on and watch them run. I believe the that I would enjoy 3R more because of the available steam (with sound) that is just not there in 2R (not as much). I have a 12 x 20 room that I can have 3 table level loops and a 4th elevated loop. I am thinking Lehigh Valley which I have always been a fan of, or B&O.
Back to thinking! The hardest part of switching to me is inventory and disposal of the 2R stuff. Much of my rolling stock started as 3R and could be changed back. I could do 3RS too with the right track choice (I am leaning toward Scaletrax).
The really dark side of this is that I am also considering Penn Central. The Penn Central Power book by Yanosey has been in my library for many years.
