The latest version 0.17.3 now supports the usage of a specific "Shuttle Train Depot" station (exact name only), trains can be sent to the depot automatically on exit (using the new On Exit setting) or via the new hotkey CTRL+SHIFT+J.
The new On Exit setting also allows you to use the hibernate trains on exit feature as a choice rather than forced action.
Any problems with the new features please let me know here or on the forum thread, Enjoy !
