Tahoe Model Works trucks feature one-piece black acetal plastic moldings with separate brake shoe detail, and non-magnetic, insulated metal 0.110" wide RP-25 contour wheelsets. Here is a 40-ton truck from the 1920s. The prototype for this truck was made by the Scullen Steel Co. for the Illinois Central Railroad in 1927 and is now at the Illinois Railway Museum. It features a spring plank and Barber Lateral Motion Device. Other railroads using similar trucks included C&NW, DL&W, NP and SL-SF. Also late 1920s-built refrigerator cars for North Western Refrigerator Line (NWX) and Western Refrigerator Line (WRX) and some North American Car Corp. refrigerator cars (NADX) and tank cars (NATX).
