Audie Murphy stars as Bill Doolin, a former train robber who gets pulled back into the game with his old gang. 

Bill is on his way home after being released from the slammer but ends up in the middle of a stick-up by his old gang. This was filmed on the Sierra Railway in Tuolumne County, CA. Sierra's famous #3 leads the train pulling an unknown baggage car followed by Coaches #6 & 2. 

After rejoining the Daltons, Bill is wrapped up in a bank robbery in "Coffeyville" - filmed on Denver Street on the Universal Studios Hollywood backlot. Some of these buildings still remain today and can be seen on the backlot tour from the theme park. 

Then it's back to doing what they do best: robbing trains! These shots were later used for the opening titles of Alias Smith & Jones. 

The gang ends up in a standoff on Main Street in Columbia City, CA (now a state park). They make their escape through the railroad roundhouse (a facade)...

...leading them to the turntable behind the Jamestown depot (now Railtown 1897 State Park). Bill fires up Engine #3 (it's just that easy!) as Cimarron Rose (Yvette Duguay) gets the turntable oriented for their escape. Engines #18 and 24 (the latter scrapped in 1955) also make an appearance. Altough threatened by numerous wildfires over the years, the roundhouse and turntable maintain the same appearance today and have been in constant use for over 125 years. The state park's excellent roundhouse tour will give you full (guided) access to the property. 

A brief scene shows Bill boarding the train at an unknown depot and inside presumably Sierra Combo Coach #5 during the gold bar heist. Then we see more obvious day-for-night traveling shots of Engine #3. 

Then the trap is set as the lawmen catch up to Bill's accomplices who are waiting at a lumber yard and trestle along the route (these shots were brightened for clarity). 

Finally the train arrives at the "Newton" depot, actually the Jamestown freight depot. Today this is in use for excursions at Railtown 1897. Even when the train isn't running, it is highly worth a visit for the gift shop and exhibits on the railroad's history (Sierra #28 pictured above in 2022).
