TSW3 Caltrain MP36 Horn Mod

This mod replaces the default Caltrain MP36PH-3C horn with a higher quality horn. This horn is from Caltrain #923, and features the signature solenoid pop that is absent on the default horn for this locomotive.

Disclaimer: This horn is LOUD on the outside! Due to the poor audio mixing and occlusion that is present on this locomotive, I had to amplify the aduio quite a bit so it would be audible from inside the cab with the windows closed.

Please feel free to give me feedback and criticism, as this is the first audio mod I've made for TSW.

Installation Instructions

This is pretty straightforward, from the zip file, just drag and drop the file named "TS2Prototype-MP36HornMod.pak" into your TSW 3 DLC folder, which is located in: Steam\steamapps\common\Train Sim World 3\WindowsNoEditor\TS2Prototype\Content\DLC

Additional Comments

This has only been tested in TSW 3, UE4 Version 4.26.1

I like very much. I'm not an expert in horns so don't know what horns sound like at all or know any of them. But I like how loud it is

Could you do the F40 horn too? It is very bland and has no doppler effect

Tested on TSW4 and it does not work. Will cause the consist to not spawn. Any chance you could update this for TSW4? Now that there are Metrolink repaints for the MP36 and cars, it would be nice to use this horn with those on the Antelope Valley Line. Any chance for the cabcar to get a new horn/bell? The bell especially since the DTG one is just the exterior bell inside the cab but quieter. Doesn't have that classic interior bell sound the Bombardier cabcars are known for. Thanks!!

Could you try it again? DTG fixed a compatibility issue with TSW4

Seems like the mod is broken with the update to TSW3 that just came out today. Any plans to potentially update it to make it compatible?

Do you think that you can do an ACS-64 horn mod with a quill function? If you could, that woukd be AMAZING!
