Hi all, i am building a small postwar Lionel layout for my son and me and being that i am still new at 3 rail i have a question on adding some sound. I have a lionel PW 623 switcher on the way and would like to add a horn or bell to it if possible, not looking for the whole sound package. Everything is controlled with PW ZW and TW transformers. What options if any do i have without upgrading my control setup? Thanks!
Ben
