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.
