As stated above, the Accucraft US narrow gauge locos are 1:20.3. This makes them scale properly to the 45mm track we all use.

The cab forward and the big boy are either scaled to 1:29 or 1:32. 1:29 is popular with garden railroaders as bigger means less problems running in the outdoor environment. 1:32 is the proper scale to make our 45mm gauge track represent 4 ft. 8 1/2 in. standard gauge. It depends on who made them as to what scale they are.

Hope this helps.

Pete,

I indicated the scale was appropriate to the manufacturer. The original post did not say if the cab forward or bigboy was live steam, so I made no assumptions as to scale.

The 1:24 was an early loco Accucraft planned. I remember seeing a model of it at a narrow gauge convention in the early 1990s. I think Tom Cruse had one also.
