Runaway Train is a single-level PWAD for Doom II and the ZDoom source port that was released in February 2001. It was designed by Nigel Rowand (Enjay) and uses the music track "Les Chants Magnétiques Part 2" by Jean-Michel Jarre, sequenced to MIDI. Apart from a brief introductory scene at a train station, the entire map is set on a moving train which is on a collision course and going to crash in three minutes, giving the player limited time to get a key from one end of the train and return.
