"Train in Vain" is a song by the British punk rock band The Clash. It was released as the third and final single from their third studio album, London Calling (1979). The song was not originally listed on the album's track listing, appearing as a hidden track at the end of the album. This was because the track was added to the record at the last minute, when the sleeve was already in production. It was the first Clash song to reach the United States Top 30 charts and in 2004, the song was ranked number 298 on Rolling Stone magazine's list of The 500 Greatest Songs of All Time.
In the US, the song's title is expanded to "Train in Vain (Stand by Me)", the words "stand by me" dominate the chorus. It was titled "Train in Vain" in part to avoid confusion with Ben E. King's signature song "Stand by Me".
