"Blue Train" is a song written by William H. Smith. Originally recorded by Johnny Cash for Sun in May 1958, it wasn't released until 1962, when Cash's long-time former label chose it as the opening track of his album All Aboard the Blue Train and for a single release.
It is a catchy, bluesy song in the "love and unrequited" vein that predominated in the songs Johnny Cash did at Sun.
The single failed to chart. According to C. Eric Banister, the author of the book Johnny Cash FAQ, the song "deserved more recognition that it got".
7" single (Sun 376, 1962)
