Older Precision Scale Gearbox and Canon motors

swrrOGR Forum Member

Pictured here is the stock gearbox and motor installed in a PSC Southern Pacific 4-6-0 probably from the early 90s. Never really seen a gearbox like this before in a Steam locomotive. It is a gear tower attached worm gear. The design is probably more common in diesels. Seems to run OK. Wondering what people’s experiences are with this mechanism, and if there are more powerful motors of this size( 1.2” diameter and 1.75” length)? Any motor longer or wider will not fit.
