An edited version of the mod "Train stations with multiple providers" by Telkine2018 (https://mods.factorio.com/mod/train_multiple_provider)

The edits as of now simply fix the crash I found while trying to use it in my moderately modded K2SE save.
the crash I encountered was as follows:
- crashed to title screen while trying to copy buildings.

All credit goes to Telkine2018, the creator of the original mod.
