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!

Thanks,

Dave

The MTH website is worth visiting. Apparently you are not getting the most from your system. Here are the conventional instructions. As a minumim you need a new Transformer with the buttons, without knowing the signal to activate a whistle. A conventional horn/whistle is just a DC pulse over AC track. Going DCS would be next, then you could program your sounds. If you find a diagram to a transformer maybe you could figure it out. So much for modern electronics.

Lionel produced the 167 Whistle Controller in the early years. If you have one, tie it in and if you have the polarity right it will ring.

Basicallly, the Protosound is sensitive to a DC pulse. One direction is a horn/whistle the other is a bell.

With a separate button, you can do both if you have a double pole switch. Neat Huh!
