Glenn,
the Bachmann 4-6-0 is based on the ET&NWC 'Tweetsie' loco from the east coast. The Bachmann 4-6-0 is painted to represent a D&RG loco. As the D&RG 4-6-0 was a T-12, then any manufacturer model would be of the prototype operated by the railroad.
The RGS 'inherited' its #20 from the F&CC and it is a fair representation of the prototype, more so than the 'T-12'. For the RGS you would need to replace the valve gear for the simpler Stephenson type, replace the steel cab for a wooden cab and do something with the 'Tweetsie' tender body.
