JD,
If you are running DCS the TIU has TVS built right into the TIU, if you are not running DCS you definitely need to add TVS no matter what Transformer, old or new that you are using.

Thanks Dave. You Answered my question as I was typing my last post.

I guess this is where I'm confused. So the TIU can control the voltage spikes before it ever gets to the track, but it's not enough to have TVS diodes only on the binding post of a PW ZW?

Where/what is the source of the transient voltage spikes? Is it in the 120v in the wall, or can a transient voltage spike be created in the layout?
