First off here are the bin files you need to activate Kuju and RWA donation ware cars.
Kuju wagon sounds.zip
Now as to modifying sounds to use Walter's sound pack here is a short explanation:
There are two ways to go about this. One way is to go into the Audio folder for any wagon or group of wagons like I did here. Find the folder in place such as this: Assets\Kuju\RailSimulatorUS\Audio\RailVehicles\Wagons folder. I'll just use one as a example. There would be a bin file named like Wagon Sound.bin Open it either using the serz utility in the Railworks folder or use TSTools which I consider the preferred method. This handy utility lets you work directly with the bin file and makes a backup in case of a mistake you you can merely delete your messup and take the .bak off of the original and you are back where you started. Or you can go in and change the bin some more and it just keeps making a series of .bak files.
OK now go into the opened file and find the lines: <SoundComponent>
<cSoundComponentBlueprint>
<ProxyName d:type="cDeltaString"> and change the statement between the carrots to say: WJ Sound\Wagons\Audio\Wagon Freight
That's it.
The second way which is much more time consuming is to go into the individual wagon bin and modify the child object towards the end where it says something like:
<ChildName d:type="cDeltaString">Wagon Sound</ChildName>
A few lines down there will be lineS that say:<Provider d:type="cDeltaString">RSC</Provider>
<Product d:type="cDeltaString">DonnerPass</Product>
</iBlueprintLibrary-cBlueprintSetID>
</BlueprintSetID>
<BlueprintID d:type="cDeltaString">Audio\RailVehicles\Wagons\Wagon Freight Sound.xml</BlueprintID>
That needs to be changed as follows:<Provider d:type="cDeltaString">WJ Sound</Provider>
<Product d:type="cDeltaString">Wagons</Product>
</iBlueprintLibrary-cBlueprintSetID>
</BlueprintSetID>
<BlueprintID d:type="cDeltaString">Audio\Wagon Freight Sound.xml</BlueprintID>
Hope that helps.
