v1.1 - Released 06/19/26 (First Release) - See List Below for list of changes made:
-Adjusts several sounds of all BOW and BPE (gameplay pack) rollingstock

Rail Singing:
-Implements Rail Singing feature onto both Boston - Providence, and Boston - Worcester (Ported from NEC: Stamford). These sounds function exactly the same as they do on NYS, in which noise from the rails ("Rail Singing") will play as the train approaches, as well as the sounds getting louder when the train reaches a faster speed when viewing the train in free camera view.

-For some reason, when opening either the driver or passenger window in the cab car when the bell is activated, the external bell is MUCH louder from the interior. Not sure if this is an audio socket issue, or if it can be fixed.
