This is posted a few other places but I figured I'd put it here too. There were some discussions/guides created about the "Single Gate Glitch" back when it was discovered that explains what we know about it, some tips/tricks, and a video demonstrating how to get it to work at an introductory level.

Since the main category of this game is split by SSG vs non SSG it seemed prudent to post those things here for posterity.

There is a reddit post outlining and discussing the discovery of the glitch with some example runs here: https://www.reddit.com/r/Sid_Meiers_Railroads/comments/bipw1x/discussion_single_gate_glitch_and_its/

There also is a video tutorial demonstrating a working example which also contains some tips and advice for trying it out yourself:

Feel free to browse and experiment yourself and let us know how it works for you. Definitely still interested in seeing others try this out and maybe find some new info or more consistent ways to reproduce.

Thanks! Choo choo!
