Factual error: The locomotive pulling the train carrying the nitroglycerin has a 2-6-0 wheel arrangement. The earliest 2-6-0 was built in 1853, 3 years after the film is set, and had their leading axles mounted directly and rigidly on the frame of the locomotive, rather than on a separate pivoting truck as the engine in the film has. The engine overall more closely resembles an 1880's vintage engine than an 1840's engine.
