Thank you both for replying, I ended up downloading a mod called Train Announcements which came with a script to add custom sounds that didn't work for me, so I manually wrote code for the mod that added the custom sound using the other sounds code as reference I spent like 2 hours trying to make it ...

Hello, I would like a custom sound for when trains arrive to stations that plays the Spanish train system jingle.

I don't know how to make mods, and it's a very small kinda sh*tpost thing, so if someone wants to point me in the right directions to do it myself that's fine too
