The Cheyenne roundhouse is home of the Union Pacific steam shops. The roundhouse houses UP steam locomotives 844 and big boy 4014. Both steam locomotives are still in operation. The roundhouse also houses other items including UP steam locomotive 838 which is used for parts and a rotary snow plow that is also still in use. At one time the roundhouse was a full circle when Cheyenne Wyoming was a main locomotive maintenance repair complex on the Union Pacific Railroad. The roundhouse is now about 6 stalls. They also give roundhouse tours from time to time.
