"Runaway Train" is a song by British musicians Elton John and Eric Clapton. It was released in July 1992 by Rocket as the second single from John's 23rd studio album, The One (1992), and was later accompanied by a music video shot the same year. It was also used in the Lethal Weapon 3 film soundtrack.
The music for the song was written by Elton John and Olle Romo while the lyrics were written by John's long-time collaborator Bernie Taupin. For the recording of his instrumental part, John used the Roland RD-1000 digital piano. Eric Clapton sings a duet with John for this track. Clapton takes the main singing part and improvised a couple guitar solos while recording. The song is in the key of G minor. For the studio recordings, Clapton used a capo on the third guitar fret, but never used it for live performances when John and Clapton went on tour in 1992.
The song was released on 20 July 1992 as the second single of John's studio album, The One, and from the Lethal Weapon 3 soundtrack. Then, it was available for several European countries. A music video to accompany the single was released in late 1992. It consists of video snippets while Clapton and John are performing the song during the Eric Clapton World Tour in London's Wembley Stadium.
