If they are scheduling days in advance, then why would a failure of the scheduling system cause an instant outage?

[naikrovek → incompatible]

because accidents and delays happen anytime, and if the schedule can't adapt, you can't run the trains.

people seem to believe that running trains is some simple thing. it is the exact opposite of a simple thing, even for small systems with only a few dozen trains

It said for "schedules for trains and staff". Crew scheduling is complicated and changes constantly.

Why not fall back to old-school time and distance interval running?

Maybe a mistake was detected and they needed to recalculate?
