Class 121 Chiltern AP Sounds and Physics Patch8th January 2019
This is a patch for the Class 121 Chiltern Railways reskins from the JT London to Aylesbury that adds AP Sound Pack compatibility.
To avoid compatibility issues this does not overwrite the default files, in order to utilise this in scenarios the default version will have to be swapped out for this version either in the editor or with a program such as RW_Tools
