This HO Scale Radio Car kit from State Tool & Die brings a prototypical replica of cars developed for remote controlled helpers. In the early days of radio-controlled mid-train helpers, Southern Railway used Radio Cars to remotely control locomotives in the middle of its trains. This easy-to-build, fully decorated 3D printed resin kit includes etched-metal antenna details, separate side and end ladders, metal wheels and Kadee(R) #158 couplers. The Radio Car will look great rolling along with your mid-train helpers.
