Circuit Board / Chip Confusion

Hi Guys

Two years ago I revived my love of model railroading for the first time since the late 50s when all we had was a circle around the tree. I'm 63.

I have a modest 8x8 layout running two tracks. An outer loop and in inner reverse Y. I've been running strictly conventional with a old refurbished ZW.

I'm in the process of purchasing a new (on order) LionChief PLUS Hudson NYC and an MTH K4s Steam Engine with PS1 from a forum member. I've been advised that there a chance of ruining the circuitry on these engines using the ZW, should a short occur.

Would someone please explain, in simple terms, how this would happen? If a train derails and a short occurs, doesn't all power (juice) stop at the pickups even if the transformer's circuit breaker takes a few seconds to trip?

A friend suggested that I install a fast-blow fuse between the transformer and track.

Thanks - Ponz
