A couple of thoughts as I migrate from 3 rail to 2 rail -- and sell off most of my 3 rail engines, (I'm keeping a hand in the game because of my modular 3 rail club) --- the four things (in addition to the obvious -- no center rail) I most look forward to saying goodbye to are:
Smoke Units. Royal pain, unreliable.
Traction Tires. Double royal pain. The time I've wasted replacing traction tires. Ever try replacing them on a Lionel SP AC-12? I did it -- one time.
Electro Couplers (even if they turn out to be scale sized in the future). I like the Kadee uncoupling action.
The extremely limited choice of wheelsets in 3 rali. Turned out to be the "straw that broke the burro's back." I was trying to 3 rail a 2 rail brass passenger car, adding Kadees to make the car 3 rail scale (3RS). The lack of choices put me over the edge to switch to 2 rail. Not to mention that 3 rail wheelsets are butt ugly. Two rail wheelsets look like jewelry in comparison.
Yep!! The decision to switch was "A Long Time Coming" True. I'm facing lots of hard work selling or converting 3 rail pieces and converting my layout. But, the angst is gone and I'm lovin' it. Man, that 2 rail track and those turnouts look nice!
Any of you who are dragging your heels like I did, please take it from me. You can do it. NOW.
