Continuity mistake: In the penultimate scene when Susan has just gotten off the train and is running to Ned Trent, you see her fall over flat on her face and then sit up. Cut to the close up where Ned has also fallen over, Susan is flat on her face again. (01:36:00)
Factual error: During "On the Atchison, Topeka and the Santa Fe", the train engineer sings "Oh, the roads back east are mighty swell, the Chesapeake, Ohio, and the ASL..." He's referring to the Chesapeake and Ohio Railroad, but the only railroad known to have the reporting mark ASL would be the Atlantic Shore Line Railway, which was an electric streetcar line established in 1900, at least 20 years after the film is set.
Factual error: During "On the Atchison, Topeka and the Santa Fe", the train depicted is a Baldwin-built 4-4-0 no. 49, the "Wm. B. Strong." The actual AT&SF no. 49 was a 0-4-0 named "Vulcan", built by Hinkley in 1876. "Wm. B. Strong" was actually AT&SF's second no. 2, and was built in their Topeka shops in 1881.
