@PRR1950 posted:You might get some customers from people relatively new to the hobby, but for those of us in too deep, you might consider how our rollers would adjust from your "lower profile" center rail to our existing "high profile" center rail if we wanted to mix the two types. Maybe some type of "sloped" connection piece? That way, if we wanted to expand an existing pike into a section that looked more "scale-like," it might be possible. Still, your biggest issue would be switches with the "lower profile" center rail; would you also produce those?
Not only couplers, but the mention of Atlas being "Code 181", would also apply to Ross/Gargraves. If you reduced the rail height to truly be Code 100, every 3-rail wheel flange would be riding on the ties! If you're thinking of only 2-rail, it's a much smaller market, but you solve the problem of the center rail.
