<P> Two Hooterville Cannonball trains used were for filming . The working model was the Sierra No. 3 locomotive, and it was used to film all the exterior "long shots", including the show's opening and closing credits . This locomotive is still operational at Railtown 1897 State Historic Park in California, after a complete restoration that was finished in 2010 . Clint Eastwood was part of a fundraiser for the restoration . He was familiar with the Sierra No. 3 from his days on the western television show Rawhide, and he used it in his films Pale Rider and Unforgiven . </P> <P> A full - scale prop locomotive was used for studio sound stage scenes . It was built in 1950 by 20th Century Fox for a movie called A Ticket to Tomahawk, starring Dan Dailey, Walter Brennan, Rory Calhoun and Marilyn Monroe . Built of wood, fiberglass and metal, it was a replica of a locomotive called the Emma Sweeny (the Emma Sweeny is actually referenced in the fourth episode of the show when a spare part is needed to repair the Cannonball), and it was pulled by a team of mules for its scenes in the film . The original 1950 cost of the elaborate studio mock - up was $40,000 . Later in the 1950s, Fox sold the locomotive replica to Harvey Dick, who used it for the décor of the Barbary Coast Lounge in the lobby of his Hoyt Hotel, an 1890s style gas - light hotel in Portland, Oregon . Harvey Dick loaned the replica to the producers of Petticoat Junction in exchange for the prominent screen credit seen at the end of each episode, "Train furnished by Barbary Coast, Hoyt Hotel, Portland, Oregon". It was also used in the show The Wild Wild West for scenes of the engine and tender . </P> <P> In the 1970s, the locomotive replica was purchased by Sacramento restaurateur / collector Sam Gordon . Gordon displayed it in the parking lot of his Sam's Stage Coach Inn (Sam's Town) along Highway 50 in Cameron Park, California, about 30 miles east of Sacramento . The replica fell into disrepair . In 1979, it was purchased by John Queirolo and Rick Stevenson, who later gave it to the Amador County Museum in Jackson, California, where it was restored and displayed . In August 2011, the Amador County museum sold the locomotive replica to the Durango Railroad Historical Society in Durango, Colorado, which planned to restore it to its original state as the Emma Sweeny . </P> <P> In 1966 Tyco Toys manufactured a tie - in electric train set . </P>
