3/4" Scale Caribou to USRA Swithcer Conversion Smo

This is designed from USRA drawings for an 0-8-0 switcher locomotive. The exauhst diameter has been left the same as to not change the mechanical aspects of the locomotive. The purpose of changing the design is to help create a modern prototype out of a design from the turn of the century. By changing it into a USRA Switcher from a candian prototype, a world of opportunity and different prototypes open up.
