I tried to accept the swinging pilots and lobster claw couplers, but when I saw Kadees could be used I didn't hesitate to make the change. Reading where folks super glued or zip tied their couplers together to get them to work made no sense to me.
I even went from conventional to DCS/TMCC, but the "atmosphere" surrounding both systems prompted me to look for an alternative. I've always been interested in RC and when I realized I could run a heavy O scale engine/train off battery power that's all it took. No sound yet (except for my 2 engines using the BlueRail board) but all engines run around the layout just fine.
So...I've gone from 3-rail to 3RS and now to BPRC on 2-rail code 148 track, still using hi-rail wheels. I don't know what to call what I have, the only thing keeping it from being entirely 2-rail scale are the hi-rail wheels, the center rail and pickup rollers are long gone from the layout.
Whatever it is I'm blaming folks like the late Ed Reutling, Martin Brechbiel, Bob Turner, and several others.
Hey...they just look better with Kadees!!!
