I'm not at all familiar with that locomotive, but if you can accurately measure the wheel's diameter at the tread, and the axle's diameter (for installation of the loco's existing gears on the new wheel sets), you can then contact NWSL to let them know what you need.

Dose any one know what NWSL wheel sets will work on TVM C420,want to change out the brass stock one. Also planning on redoing the handrails on these units,dose Kemtron make a set of stantions for these units?
I have two Tiger Valley Model C420, they do run (DC) only. They both have brass wheel sets. Dose anyone know if you can swap them for NWSL nickel silver wheel sets?
