Thanks Steve, I appreciate the recommendation a lot. I assume I would wire that Instant Breaker on the "hot wire" going to the track? See diagram below.

I would rather do it right the first time than do any short term solution like you mentioned. Then when it is installed I am able to reset it with the switch instead of actual fuses?  Yes

As far as TVS diodes, I saw this one to be what I think I would need? part number 1.5KE33CA‎ -Yes this is the recommended diode

is it worth ordering from them for 25 shipped for $16 or go with this amazon deal?

Then because I plan to run legacy, can I still put one at the terminal post and then also the track pick ups?  The best places for TVS Diodes are as close as possible to the sensitive electronics you're trying to protect.

You're welcome.  See my answers above in quote box.

Here is a diagram for how to connect a breaker to a single transformer and track along with two TVS Diodes on opposite ends of the layout.  Larger layouts may benefit from additional TVS.  But, the best place for these diodes is inside the locomotives they're intended to protect.
