Johnny it would make sense that the horn would be the loudest. It being a warning rather than a courtesy get out of the way signal.

Thanks Joe.

I just purchased a Sound Value RS3 and the sound is so low I can hardly hear it. I have a Bachmann DCC system and I was told by Bachmann I could not use it to change the CVs to raise the volume since it didn't have the necessary controls. I was planning on visiting a friend's layout who has a top of the line DCC system to see if he could help. Any ideas would be appreciated.
