Locomotion is a decent action/puzzle game with nice VGA graphics and adlib music.The game principle is not new and widely known but well executed. Navigate trains to their destination stations by switching the lines. Things get harder each level, when the railroad layouts get more complicated and more and more trains are coming out faster and faster. If two trains crash, they are lost. The game contains an editor for creating own levels, so replay value is high. Overall, a good variant of LucasFilms' earlier Pipe Dreams, and well worth a look by puzzle fans. Thumbs up!
