electric airplane at lunch today!) I can assure you that doing this will NOT fry
the motor/controller/transformer. It just helps keep things cool and reduces
arc'ing while rubbing in the brushes. This is always done undervoltage, and it
should be DISTILLED water (which we all know is nonconductive, right? =)
In general I prefer a no-load, undervoltage run-in. Most of the brushes are
fairly soft so doing it for HOURS seems excessive to me, but maybe the train
motor's are harder. What is important is that AFTER the break-in you CLEAN the
motor/brush/commutator/etc...maybe in the middle of breaking it in, also, to
help remove the little cruds (technical term) that show up.

- Just a note: Distilled water is electrically non conductive...
Deionized water is not...
running it in distilled would probably be ok, make sure the bearings
are lubed and dry the motor out well... (leave it sitting in the sunlight
for a while)
I like the idea of a fluid washing out the bits of brush...

Those are some interesting ideas about breaking in motors.
Item 1 doesn't sound like it would cause any problems, and it might
help break in the brushes, although, I'm not sure that's even
Item 2 sounds like something to avoid at all costs as Z scale motors
are completely exposed whereas RC motors are sealed so they can be
used in boats as well as other vehicles. I suspect you'd at least
blow a fuse or circuit breaker if you were fortunate enough not to
destroy the motor and/or possibly your transformer.
Item 3 doesn't sound like it could cause any damage, but
Item 4 also sounds like something to avoid as I'm sure the lube oil
would pick up and retain all the small debris found on our layouts
and would make cleaning very difficult.
With regards to Item 5. You do plan to run your engines backwards
once in a while, don't you??
I generally just run the new engine around the layout for several
hours, at varying speeds and in different directions, as well as
running it forward both alone and with a load for some length of time.
I've never had any trouble with any of my locomotives using this
