Durango in La Plata County, Colorado — The American Mountains (Southwest)
Emma Sweeny Movie Star
A Ticket to Tomahawk
In August and September 1949 20th Century Fox filmed A Ticket to Tomahawk, mainly in the Durango and Silverton area, with camp scenes at their studio in Los Angeles.
The cast included four dance hall girls, one of whom was then-unknown Marilyn Monroe.
The real steam locomotive RGS 20 was used in shots on tracks in Silverton, Animas Canyon, and on the old RGS trestle over Lightner Creek just west of Durango.
Studio craftsmen built a full-size replica of RGS 20 as Emma Sweeny for use in scenes off the tracks in Silverton and Durango, on Molas Pass, and camp scenes at their studio.
The Movie Plot
Set in 1876, the movie is about getting a train and at least one paying passenger to Tomahawk by a deadline a few days away, to fulfill a contract and save the franchise.
However, 40 miles of track are missing between Epitaph and Tomahawk, so the locomotive is pulled over a mountain by a team of mules.
A competing stagecoach line will do anything to prevent Emma Sweeny from arriving at Tomahawk before the deadline.
Petticoat Junction
In 1960 the studio sold Emma Sweeny to a private party. The model was leased for use in the TV series Petticoat Junction and transformed into the Hooterville Cannonball. Later, Emma Sweeny was on public display in Oregon and California.
Amador County, California
In March 1980 the model was donated to Amador County. It was renamed Amador Cannonball and displayed in Jackson, Amador County. Many original parts were missing.
Durango, Colorado
In April 2011 Amador County donated the model to the Durango Railroad Historical Society. DRHS restored it during 2011-17 to its original movie appearance. Fortunately, copies of studio drawings were found, allowing an accurate restoration.

Excerpt: The 1899 Schenectady locomotive RGS 20 (4-6-0, Ten-Wheeler), originally F&CC 20, acted as T&W 1, Emma Sweeny [in A Ticket to Tomahawk]. It was adorned with false funnel stack, long wooden pilot, link and pin coupler, oil or kerosene headlight box over the electric light with a set of six-point antlers on top, and a fancy and colorful paint scheme, including three-masted sailing ships on both sides of tender.(Submitted on March 9, 2026, by Cosmos Mariner of Cape Canaveral, Florida.)The Twentieth Century Fox Prop Shop built the accurate, full-size model locomotive in the summer of 1949. It has a steel frame, with wood, fiberglass, and metal parts, and weighs about 18,000 pounds. The model was so good, it could fool experts exclaimed Hank Philips, retired fireman who worked as fireman on RGS 20 and was a stand-in for Arthur Hunnicutt.
Because the model had to be pulled, it has a steel frame, steel pipe axles, and iron rims on wood wheels. Most of the model is wood, but some parts are metal or fiberglass. For example, handholds, fire door, ladder, journal box covers, and several brackets are metal. The steam dome, sand box, and much of the boiler are fiberglass. Piping, pipefittings, and valves are real.
