This mod replaces the default hornsound for the AC4400CW locomotive from either Sand Patch Grade or Cane Creek (depending on which file you choose), to a more accurate sounding K3LA horn, recorded by me (The audio that was recorded was actually taken from a BNSF C44-9W locomotive, though I thought the audio fit well on these locomotives). This horn is a three part horn, meaning that there is a start and end sound file that will play when sounding the horn (see NOTES below).
NOTES:
-CANE CREEK: In order for this mod to work properly, you MUST have SpaceyKat's Cane Creek Patches mod (the CCBSubbing file to be specific), as this mod utilizes files from that mod for the three part horn to work in the first place. Not installing the Cane Creek Patches mod will cause the horn audio to not work properly as only the looping sounds will play if not installed.
-SAND PATCH GRADE: In order for this mod to work properly, you MUST have both SpaceyKat's Sand Patch Grade Enhancement Pack mod (the AC44 DitchLights file to be specific) , as well as CAMOGUY54321's AC4400CW SPG Horn Mod, as this mod utilizes files from those mods for the three part horn to work in the first place. Not installing the two mods will cause the horn audio to not work properly as the start sound will not play if not installed.

A TSW2 version mod will work in TSW5? I did not think this was an option. Also just a heads up not all will the game installed to the C drive I have the games on a G drive, this may confuse anyone new to adding mods, into their game.
Not sure what you mean by TSW2 version of this mod, since this was made to work with TSW5 (you can try it with the older games though I highly doubt they'll work)
I'm aware of the DLC folder location being different for other users, just don't really have the time to reword it, but I assume that generally speaking, most TSW will have the game installed on a C drive, and will have a similar looking file location.
My apologies, I neglected to point to "Cane Creek Audio Mods by Griggs" https://www.trainsimcommunity.com/mods/c3-train-sim-world/c20-sounds/i1527-cane-creek-audio-mods. This was made for TSW2
It is all good, just a suggestion.
Ah I see. Yup, some mods from that game will still work for TSW5, though they might have a few issues. In this case, I don't really see any as far as I'm aware.
Okay, very good, thank you for getting back to me and for making these mods.

Looks like the mod works great on the clean version of the AC4400, except on the dirty version the 3-part horn fade in and out don't work.
