I'm new to the forum and hoping y'all can help me with a problem. I've got an old Lionel ZW transformer and am running an MTH loco with Protosound 2. To activate many of the protosound functions I need a "bell" button and don't have one, I only have direction and whistle buttons on the old ZW transformer.
What's the easiest way to add the functionality of a bell button?
All help appreciated very much!
