In the 1950s the Southern Pacific updated their This Is My Railroad film to feature the new diesels which were being used for both passenger and freight service. E-units and Alco Pas in the Daylight paint scheme are now pulling passenger trains, and the freights are being pulled by F-units in the famous Black Widow paint. There are still a few steam locomotives seen along side of the diesels. Also on this tape is Big Trains Rolling. The American Association of Railroads produced this 1950s color film, describing the importance American railroads play in our everyday life. The film features mainly first generation diesels used by many of our major railroads. 55 Minutes Color DVD
