Bachmann's On30 Mogul Translating to 55n3

[hminky]

I found a Mogul that mechanically matches the Bachmann On30 Mogul if it were used as a locomotive in 55n3. The On30 mogul scaled down to a "modern" Baldwin narrow gauge mogul in 55n3 but the Baldwins didn't have 44" drivers. Brooks built the Colorado and Northwestern a mogul with the same mechanical dimensions with 44" drivers.

44" drivers would be plausible for a model of the East Broad Top's 2 "big" moguls, nos. 5 and 9. Number 9 was originally built for the Coeur d'Alene Railway and Navigation Co., and was successful enough to where the EBT ordered their 2nd #5 as a copy. Those moguls had 48" drivers--a bit larger than what these would scale out to, but it'd still be pretty darned close. (Besides, after a few shoppings, the driver diameter would be reduced due to re-turning the drivers on the wheel lathe. I have seen drivers that were reduced 4" from their original driver diameter.)

The On30 Mogul could be used many locos. The problem is finding plans or side photos. It is close to the EBT 2-6-2.

Kevin is right that the 44' drivers should work fine, although losing 4" on the wheel lathe sounds like a lot.  Please note that many (most?) model drivers tend to be a little on the small side due to the conflicting needs for oversize flanges, which push the wheels apart, and keeping the overall wheelbase close to scale.

Could be made into a EBT Mogul with 48" drivers, HO 22mm are the right size.
