Locomotion is an arcade-puzzle game with a railway theme, created by Swiss game designer André Wüthrich and released in 1992. Wüthrich, a native of Winterthur, was responsible for the design and programming of the game on the Commodore Amiga, which served as the lead platform. The game was developed under the label Prestige Softwareentwicklung GmbH and published by Kingsoft GmbH, a German company based in Aachen that had been one of the most active publishers for Commodore home computers since the early 1980s. Kingsoft commissioned ports to the Commodore 64, Atari ST, and DOS, which were handled by other programmers. The graphics for the Amiga were contributed by Harald Kuhn, and the music was composed by Matthias Steinwachs.

The player is presented with a top-down view of a small, self-contained railway network that resembles a model train layout. Trains depart from stations at random intervals, each assigned a random destination. The objective is to guide a set number of locomotives to their correct destinations by toggling switches at junctions—all within a time limit and without exceeding a maximum number of collisions. If a train reaches the wrong station, it simply reverses and continues, a mechanic the player can exploit to change direction. Trains encountering a switch set against them will stop, which can be used strategically to hold traffic. Wüthrich has described the game as being inspired by the Amiga Games “Kennedy Approach” – an air traffic control game –, and “Pipes”. While he mentions that he is "not really a fan of locomotives", he values games demanding constant concentration and rapid response[1]. The game shipped with 108 pre-built levels organised into twelve sets of nine, with progressive difficulty and a password system [R1]. A comprehensive level editor allows players to create another 108 custom levels with configurable parameters for time, speed, traffic density, simultaneous trains, and collision tolerance. The disk was distributed without copy protection, using instead a manual-based railway trivia quiz as its anti-piracy measure.

Contemporary press reception was mostly positive. CU Amiga awarded the Amiga version 80% in August 1992 [R2], Amiga Power gave it 84%, and Amiga Action rated it 68%. Commodore Format featured a demo on its January 1993 cover tape and rated the full game 74%, describing it as "less a puzzle game and more a test of your organisation and cool". The overall critic average on MobyGames stands at 73%. Retrospective user reviews have been warmer: the game holds a 7.8 on Lemon64 and 7.56 on the C64-Wiki. Wüthrich himself has conceded the game became "a bit too difficult"—a trait he recognises across all his work, noting: "a programmer should never test his games himself." [1]
