I am thinking of a small 0-4-0 steam loco.
The potential problems I can see are:
The width of the gearbox, although slim designs are available or an extra gear or two could be added and mount the gearbox above the frame.
The axles would be too long but these could be shortened.
Check-rails on the points would need moving for the extra thickness of the wheel flanges.
Any other problems/ advice
