All Aboard! The Railfair is a free event at Scottsdale’s McCormick-Stillman Railroad Park October 11th and 12th. It features model train displays, exhibits, the park’s award winning Model Railroad Building displaying O, N, and HO scale trains, moonwalks, and other entertainment. Free tours will be offered through the Roald Amundsen Pullman car, a former presidential car. Also, many of the park’s seldom seen railroad equipment will be on display. Train and carousel rides are $2.00 each. Children under three ride free with a paying adult.
