Jerry:
Ticket to Tomahawk was mostly filmed on the Silverton Branch except for one scene on Lightner Creek trestle on the RGS circa 1950. Bob Richardson took a photo which is in Dorman's Durango book on page 83 which doesn't appear to show the 2nd spout and is dated 9/11/52 which is probably accurate as RGS #42 looks to be in her scrapping atire.
Which leaves us with post 1952 films which would have included "Three Young Texans" 1/54, "Run for Cover" 4/55, "The Maverick Queen" 5/56, "Around the World in Eighty Days" 10/56, and "Night Passage" 8/57....
