Making local trains run on time is more important to governments than most people feel it is. The clockwork precision of a well-run train system evolves into something resembling magic. Each layer of the setup builds on the one before it, the consequences pile up and become larger than the sum of their parts.
The psychological balance of the populace depends on the margin of error being maintained over long years. If the tolerance is exceeded, you have a simmering public that could burst at any moment of time.
So all those people you see telling their bosses that the trains were late and stuff. Nope, doesn’t happen. They’re not lying or anything. They’re just conditioned.
