2 rail certainly is the future.................
In HO, N, Z, TT, G, Live Steam, etc.
It's a good option in O but I can't see 3 rail disappearing.
To quote Hank William's Jr, not matter what happens in all of this "America will survive". Even if I gave up trains, there's no shortage of hobbies I am interested in. In fact, I have that issue now, too many interests, too little time and money for it all.
