A key feature of celestial bodies is that they are NOT UNDERGROUND, which
makes seeing what's going on in the vicinity of them rather easier.

I think a whizzy high-tech moving block system can avoid these problems,
though; the system would (or should) have a battery of redundant sensors
and communications links, so it can keep accurate tabs on every train at
all times.
