Hi Guys:
Here is a photo of a 1/24 scale standard gauge NYC 5200 Hudson:

The model is from the 1930’s.
Track gauge is 1/24 of 4 feet 8 1/2 inches.
Alas, the largescale mfgs. chose to not pursue 1/24 scale.
The photo shows what could have been in terms of a common 1/24 scale for both standard gauge and narrow gauge.
Talk about the 1/29 WOW factor ( to which I agree ) , How about the 1/24 scale WOW factor?
