One of my all time favourite Christmas movies, White Christmas features a pair of passenger trains. This is what I found when I did some research;
"The first glimpse of a real train follows a dining car scene. It's a daytime scene darkened to appear like it's at night, and it shows a long Santa Fe streamlined train behind four Santa Fe warbonnet F-units, (A-B-B-A) running alongside the ocean in front of palm trees apparently meant to suggest "Florida" but undoubtedly actually on Santa Fe's "Surf Line." The next scene, depicting a daytime segment of the trip, shows a Southern Pacific passenger train, with an A-B-B set of F-units in Black Widow paint, followed by several heavyweight head end cars and a string of heavyweight passenger cars."
