The horn on the RABe 523 is completely broken. The sound files do not play externally and will only work if you are either in the cab itself, or have your camera press right against it. This needs to be fixed.
dude i didn't even know the outside horn worked at all, I thought they messed up with programming that it didnt pick up the files and ended up with nothing at all, but the fact that there IS an outside horn, just that you have to be really close, is awesome actually. this could either be fixed by rivet or DTG when we continue to tell them, or we just ask a modder of they could fix it (but then it'd be pc only though)
Broken since an update some time ago on Xbox SX, it worked at release then stopped after a few seconds into each time you load it up.
It appears that I am hearing the horn coming from an alternate universe aka. like 200 meters behind me???
Okay the horn is just so broken that I am gonna list everything that's broken plus the things that work 1 - when from inside, it is normal, fine 2 - when from outside, it is either not working at all, only when you're incredibly close to the train, or the sound comes from far behind you, which is unexplainable and totally unreasonable 3 - when activating horn from inside, then changing view to outside while holding space or N, it sounds normal, but when you release and redo it from the outside, observe number two 4 - actually ignore number two almost entirely because the exterior horn's source spot never moves with the train, when I spawned the train with Godmode and then drove away, I found out the horn sound comes from the exact same spot where I spawned the train, where in timetable mode on the S-Bahn Centralswitzerland, the origin point is probably stuck in the deep void below the map??
The exterior horn was fixed in an update. I was playing with it in tsw3 on pc and it worked fine. It's mostly for distance but I've not actually tested it
