English: Postcard photo of the Missouri Pacific Scenic Limited leaving St. Louis. The train traveled between St. Louis and San Francisco. It was routed over the Denver and Rio Grande and Western Pacific Railroads, as it went through the Royal Gorge and Feather River Canyon.
Date
Not mailed or otherwise dated. The train began in 1915. Since the photo shows a steam locomotive, it would probably date before the 1950s, as diesel power was most common after that point. Any passenger service remaining on the MP in 1971 was turned over to Amtrak.
The card has no copyright markings on it as can be seen in the links above.
