Does anyone know if the Bachmann's non spectrum 2-6-0 mogul engine drive wheels are gauged to NMRA standards? The reason I ask: Do to some very good reviews of the 4-8-4 Northern.  I decided to purchasethe 4-8-4 Northerb (current run). The wheels were out of gauge and when I gauged the wheels they lost friction on the shafts and will not stay quartered. The engine is now slated for the junk box.
