How many more years you need to fix the goddamn horn? The bug is there from TSW3 early access release! Press the horn and with a certain probability you will go to the wonderland of stuck horn sound for the rest of the drive.
I do believe I have never sounded the horn on this route due to this bug and that was the case when it first came out and I was losing many hours to it. Hardly use the route these days but am eagerly awaiting the High Iron pack that’s coming to get back into it with new gameplay. For bugs like this, stuck sounds, sounds not playing, wipers stopping working etc, I believe the way to fix them is to go to the free camera and fly far enough away from the train so that it has to completely reload when you return to it. I have no idea if it works in this case but it does fix some similar issues.
