Rail | Classic retro game for the Commodore PET Computer (1980)

RAIL is a puzzle game in which a set of unstoppable trains move around a map of tracks. Your goal is to guide one specially-marked train to a siding while operating twelve track switches to prevent collisions and derailments. So far, I've managed to safely guide the train with a total of four trains moving around the tracks—you can have up to six trains in motion, so the game can get quite tricky. (Watch out for switchpoint 'J' at the very beginning of the run.)

Owing to the limited RAM of the PET, there's only one track layout in the game.
