McKeen Motor Car No. 22 is the only operational railcar of its type in the world. The self-propelled passenger car was put into service by the Virginia & Truckee Railroad in 1910 and spent many years traveling the runs between Carson City, Minden, and Reno. The grade up to Virginia City was too steep for the McKeen to handle with the gasoline engine it was powered by. After being retired in 1945, the car floated around Carson City and was put to various uses. The museum acquired the car from a plumbing company that had been using it for an office. After over a decade of restoration work, McKeen Motor Car No. 22 is open to the public and runs excursion rides on a variety of special occasions. The magnificent car is one of the crown jewels among the collection at the Nevada State Railroad Museum in Carson City.
