ATS - Improved Train Sounds V2.11 (1.38.x)

This mod replaces the standard trains sounds in ATS with improved versions.

As of game update 1.5, the new "AI" trains will now spawn with a minimum of 12 rolling stock (value may increase in the future).

Version 2.11 Changelog:
- Update for 1.38;
- Adjusted Safe Distance parameter to (hopefully) help trains spawn a bit more.
