Hi, I came across some YouTube videos in which the author uses sounds relating to railway switches that are very faithful to reality and different from the default ones and those obtained by modifying the ttype.dat and .trk files of the different routes. I specify that I contacted the author of the videos via email provided by him in order to have explanations about it some time ago, but I have not received any response. With the help of the example link relating to one of these videos at the end of this message, would you have an idea on how to integrate them on any route? Waiting for a reply, best regards. https://youtu.be/1XGW9VthtTk
