First, test the modules as they are added to the system to make sure they
meet the minimum requirement. Second, watch the whole thing like a hawk, being
ready to shut it down to fix such problems. Third, there will have to be some
special-purpose modules within the system, such as the first "timing module", a
"return module" (like Steve's train), perhaps turn modules, etc. A very simple
bypass module can be built (I'm working in it) that can easily be adjusted in
length "on the fly" so a malfunctioning module can be hot-swapped out of the
line.

At this point, most if not all of the modules I've seen can "run dry", so
there's not need for a module to check for itself.

Yes. Babysitting will be needed.
