Modeled after the Two-Truck Shay Locomotive that was built in the 1920s, this type of engine was used by many lumber, mining, quarry company railroads, other industrial railroads, a few common carrier short lines and major railroad systems for service in the logging and milling industries.
 
This new model features a diecast frame and boiler, drive shaft detail, operating drive-shaft, directional lighting, all wheel drive and electrical pick-up, separately applied grab irons, prototypical painting and lettering, AccuMate(R) knuckle couplers, DCC-capable motor isolated from frame. Like the prototypes, these locomotives can negotiate very sharp curves down to a minimum radius of 9-3/4".
