"Reuben's Train", also known as "Old Reuben", "Reuben", "Train 45", "Riding on That Train 45" or "900 Miles" is a lyric song from the South. It is member of a family of railroad related songs that include "Nine Hundred Miles", "The Longest Train", "In the Pines" and others. It was printed in Lomax's Folk Songs of North America and appears in the Roud Folk Song Index as #3423. It was recorded in 1927 by Grayson & Whitter as "Train 45", Dock Boggs as "Ruben's Train", Elizabeth Cotten as "Ruben", J. E. Mainer's Mountaineers, "Riding on Train Forty-Five" (1937 & 1941), New Lost City Ramblers as "Riding on That Train 45", Wade Ward as "Old Reuben", Doc Watson as "Old Ruben" and a number of others. The tune is similar to to "Rain and Snow" but is in a major key while "Rain and Snow" is a Dorian mode tune. There is a remote possibility that this song has something to do with railroad engineer Reuben Wells who built what was at the time (1868) the most powerful locomotive in the world. It was used to push freight up the 5.89% incline of Madison Hill in Madison, Indiana, the steepest segment of standard-gauge main-track in the United States.
