I don't know if this is the right forum to post this in, but I found the source of the K5LA (KUID number: kuid2:126323:54722:1) used on the P32s in Trainz. I put the horn in Google's music finder (works like Shazam) and I found that this exact horn is in "Wetsock - Crackhead TV". I figured that the horn was in a song for some reason.
