Will someone please clarify if "3-railscale" excludes those who purchase MTH Premier, Atlas and Weaver engines and cars that have the correct dimensions and details but use "oversize couplers", oversize rails and wheel flanges?
I scratchbuild many railroad cars based on prototype drawings and dimensions but are designed to operate with my existing 3-rail engines. If I change to Kadee couplers and scale wheels would they now be classified as "3-railscale"?
Samples attached.
