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.
That was the exact diagram I was thinking. Thank you for the reply being color coded and understandable.
Because I plan on a train shelf I will have pickups at two other locations that I can put the diodes on.
As far as inside the train itself, I have been in my LC2 Big Boy a few times and am comfortable in it. Would it be the same diode installed there? and where would I be looking to install it? I assume the power pickup area but unsure about "how" to find that inside the train.
Really appreciate you taking the time to respond to me and my questions.
