Auto-Build Railways

If God had intended us to fly, he’d have never given us railways.
– Michael Flanders

This mod aims at making railway expansion smarter! Now, railways will auto-expand whenever market access is below 100%; or, the building has a lot of potential to make money by selling transportation. Of course, all of this only works when you have auto-expand turned on.

Auto-build only works when the building is either subsidized, or cash reserves are at 0.75!

This mod was built for version 1.0.4, but should work on any (future) version of the game, as the adjustments to the files are very minor.

This mod works as a standalone.
This mod is compatible with most mods (most notably Anbeeld’s AI and Improved Automation).

If you use ‘Anbeeld’s Revision of AI’ and/or ‘Improved Automation’,
Put those mods in the following order to prevent bugs:
1. Anbeeld’s Revision of AI
2. Improved Automation
3. Auto Build Railways

1.0 : Mod created.
1.1 : Increased min. profit of the railway from 1 to 10, to prevent runaway railway construction.

Credit goes to the Anbeeld’s revision of AI mod!
Note the most important change relative to the Improved Automation mod is the < changed into <= , as the game doesn’t understand what < means. This is apparently bugged in Paradox Games.
