I've got an old Roundhouse 4-4-2 that was forgotten in the attic. It seems to run alright, a bit wobbly on curves, but its extremely noisy. Would a motor swap do any good?
The gears are all plastic, I checked that earlier as I thought the same as you. Obviously the wheels have no proper bearings, so could that be the issue? All that weight coming from the diecast chassis and body grinding against the axles must make some of the noise...Probably not the motor, although the brushes might be worn.
I'd be more inclined to suspect the gears, which I think are metal castings. I could be wrong though.
Thanks👍I have one in the southern pacific livery that I did a can motor swap on and it made a big difference in noise as well as low speed performance. The only issue I have with it is the motor I installed makes the loco run very slow for it being a “passenger loco” if you’re not worried about speed go for it but if you are I would get a high rpm motor or change the gear set
