As has been said by others we should be pleased Beth has taken up the possibility to provide a reasonably priced end cab switcher. O scale is in yet another transition. I used to say there was Atlas at one end of the spectrum together with Sunset in the middle and Key at the top. Key is inactive and Atlas lost its O scale champion when Bill Weaver died. So no use in being critical. I am of the strong view whether you're modelling in 2 or 3 rail it's all one hobby. So Beth thank you and please keep plugging away as many of us are very supportive of your initiative.
