A little history. NASG adopted its current wheel and track standards in 1981,
I believe the Sunset Bog Boy was 1984 or later(?). After the NASG adopted
those standards, they were sent to anyone announcing new models in S scale.
OMI's first offering (SD40-2) was built to the "old" NMRA. They subsequently
moved to the NASG. Sunset was contacted and chose not to change. Later NMRA
standards were changed to align with the NASG's so now there is "harmony" in S
Scale! (Boy does that sound like an oxymoron...!)
My personal experience is that locomotives made to the older NMRA standards,
like the Sunset Big Boy, will bump through newer trunouts and may or may not
opereate reliably. Of course adjusting back to back measurements on steam
locomotive drivers to 0.800" is not for the faint-of-heart!
