TVS diode?

So I'm probably going to annoy a few people by asking this, since there are two other threads about this, but I don't understand what these are and why I need them when I already have fuses for my old ZW's?

I mean, I know the fuses (and soon circuit breakers) protect me from shorts when I derail a train, but I don't understand the TVS. However, I figure it might be a good idea, since I had a board go a few months ago in my Porter without a derailment, and I'm still trying to figure out the cause.
