# Railway corridors for Treasurer [`tsm_railcorridors`]
* Current version 0.11.0
Minetest mod for adding underground corridors with rails and wood constructions with
a few treasure chests now and then. Optional Treasurer support is available for adding
treasures from various mods.
Use the advanced settings to finetune the railway corridors.
* Forum thread: https://forum.minetest.net/viewtopic.php?t=10339

## Info for modders
Want to include this mod in a subgame, but you hate the dependencies?
You can edit the node names in gameconfig.lua to fit your needs. :-)
