This GP-40 was built by Gene L. for his wife Joan. This locomotive took about 9 months to build and was modeled after an HO scale GP-40 and scaled up to 1/8 scale. Gene had a sheet metal shop form the body panels and then he welded it all together. He also built the trucks which are powered by a 16 HP Briggs and Straton twin V engine turning a hydro static pump transferring power to the hydraulic motors on each truck.
