TVS Diode Installation at Track Level

I see you have another thread on a related issue.  The link GRJ posted is a good one.  Here's another one where I was spectator to all the gurus.  Note the posts by @SteveH as they are very insightful.

Thanks texgeekboy for the extra articles.

Hi GRJ,

I realize this post above about installing TVSs is elementary but after my TMCC Lockon 'goof' I am sensitive about mistake avoidance. Do I understand correct - the direction does not matter?

A second question --> where can one get the TVS installed in newer locomotives? Losing one due to a overload would be more than painful!

- I have two New Vision, four (three New, one LN) Legacy, and two (LN) TMCC engines - patiently awaiting my getting my new layout running.

Ken, you're correct.  Because the TVS diodes you're referencing are bi-directional, either lead can be connected to Hot and the other lead connected to Common.  In other words, they don't have a polarity like normal diodes.

Regarding installing TVS in your locomotives, are you looking for someone local or are you willing to ship them?  If shipping is an option, you are welcome to contact me at the email address in my profile to discuss this further.
