There’s been an open collaborative project for the last two years on a corner of 4chan to create a train based wargame.
Set in a weird world of supernaturally growing and shifting rail lines covering the planet, like unstoppable weeds, the trains of various factions do battle with cannon, ramming, and boarding parties.

The project has moved into actual playtesting and balance tweaks.
I haven’t had the chance to dig into the rules and try them out myself, but I wanted to give access to what’s avaliable so far to train and tabletop enthusiasts alike.
I’ve compiled all the most up to date rules in a Google Drive link!
