Well, I'm glad I "sparked" some discussion on this subject!
Sorry, couldn't resist.
A short circuit downstream of the transformer and upstream of the locomotive appears as a zero-voltage source to any electronics in the locomotive. Zero voltage is not harmful. What might damage the locomotive is voltage spikes occuring when the short circuit is removed. The surest preventive for that is not a circuit breaker, which limits overcurrent, but a transient voltage suppressor, which limits overvoltage.

yes you can run MTH PS3 stuff on tubular track & 022 switches (if they take the curve). While I love the old style transformers, I would have to agree that it is best to use a modern transformer w/ a quick acting breaker to protect the electonics in the engine. If you really want to use your postwar transformers, place an inline fuse between the track & transformer. This will help protect the engines if there is a short

Since no-one else has responded, and not considering myself a super expert, let me just give you my two cents worth.
Many folks are a bit leery of running the current generation of locomotives with their sophistcated electronics with post-war transformers. At any rate, you'll never get everything out of those engines that they have to offer with obsolete ZW's or KW's.
I run all my stuff with MTH Z-1000's, I think it's safer to do so, and my post-wars run great with them as well. I DO have two KW's but those are for under the Christmas Tree with the post-war engines, although I have to admit I've run the new stuff with them and had no ill effects.
What track you use shouldn't make any difference at all.
I do like the quick circuit breakers on the Z-1000's and they are FAST!
