Just not practice for me. Too time consuming, costly plus you still have the look of 3R thick toy HI rails.
I don’t notice couplers on operating trains anyway. Besides, you still have a more noticeable middle rail, thin axles no cut coupler bars and large incorrect wheel flanges. I don’t see the point.
All model O trains should have always been 2 rail from the beginning.
Sorry Joey, I just can't go with it.
Hey Steve, I understand! This niche within a niche definitely isn't for everyone. I'm not even sure where I'm headed with it. But I am sure of two things: 1.) I like the looks of the smaller couplers a heck of a LOT better, especially on locomotives, and 2.) I won't have to worry about surprise coupler openings and having my locomotives ram into the back of their own train anymore...which only seems to happen when I walk away for a few seconds (like to grab a cold beer)...LOL!
