The Proto code 87 wheels will NOT operate on NASG/NMRA "std" track. The tread profile is all wrong and the wheel flange is too narrow. The code 88 NASG/DePlains wheels from NWSL are RP25 and will run in NASG/NMRA flange ways. Versly, code 110 and 88 wheels will not fit thru a proto flange way.

To be specific. The AG wheels are to the British SMRS standards and will NOT work thru a NASG flange way. They will pick due to narrow/ shallow flages. As to there tread profile working on tangent american rail gauged to NASG I dont know. ask here <http://www.s-scale.org.uk/> TCC:} On Sep 14, 2008, at 9:56 PM, Darrell Smith wrote: > Gentlemen, > > I am working on a few identical 4-4-0 models, converting static models > to operating models.
