Loco is a 1984 computer game developed by Antony Crowther and released by Alligata for the Commodore 64. In 1986 it was converted for the ZX Spectrum and Atari 8-bit family.
The ZX Spectrum version was developed by Richard Stevenson, David Wright and Nigel Speight.
The music for the game is a C64 remake of Jean Michel Jarre's Equinoxe 5 by Ben Daglish.
Comparing screen shots and game descriptions, Loco appears to be a clone of the arcade game Super Locomotive, produced by Sega in 1982.
