Those packs include rolling stock. So, I have to add the correct files to the installer to update the bin files for those new pieces of rolling stock. Otherwise, they use the default sounds. So, if you make up a train with those new wagons, they will sound funny as they will not have Krellnut's sounds applied.
The good news is this, I'm finished updating the pack. I'll be uploading it shortly. Then it is just a matter of when Bob get's around to adding it to the file library.
Oh yes, for those of you who do not like the new track joint sounds, I've included an installer to replace them all with the default this time. No need to download a separate fix as with version 3.0.
This pack (3.1) will install clean over 3.0. No need to uninstall anything. For those of you who don't have version 3.0, this is all you need. It is a full installer.
