I posted this question on the 3R scale forum, but I'm not getting any useful responses. Would anyone know the flange depth on 3rd Rail, 3 rail locos--and would the wheel flanges hit the spike heads on Atlas c148 2-Rail track?
It seems to me that radio control would be a viable option to convert these 3-R steamers to 2-rail operation, but it would be more practical if I didn't need to turn the flanges down on the wheels.
Ideally I would want a deeper flange than the 2-rail versions of the locos (to help the locos negotiate sharp curves), but not so deep as to bottom out on spike heads.
Turnout flangeways will be another consideration, but I think that can be solved now that I have the ability to scratchbuild a turnout to fit my needs.
