I'm currently in the design phase for a new layout, and I want to incorporate Atlas' O-54/O-72 switch into a mainly FasTrack layout. While doing some research on how to do that, I came across MTH Product numbers 40-1064 through 40-1067 - Double-Curve switches in the RealTrax line, an O-42/O-31 pair and an O-72/O-54 pair. I figured these would be easier to incorporate than the Atlas version, but aside from their existence on the MTH site, I can't find any other evidence they were made. Were these switches cancelled? If not, does anyone know of any hobby shops that have some? I'd specifically need 40-1066, the O-72/O-54 Right Hand version. Any information is appreciated. Thanks!
