the email "Why don't Atlas use.." yeesh.Actually, no. The only wisdom the NMRA has on the subject is RP-23,
last revised in August of 1961. RP-23 calls for the centerplate to be
5/16" (.3125") above the rails, with a .089" diameter hole.
The defacto industry standard for the last twenty years has been the
centerplate .290" / .300" above the rails, with a hole that provides
clearance on an 1/8" boss, .126" / .130".
What are the dimensions of the new Atlas trucks? If they are too high,
they may be doing exactly what you ask…
