My curiosity is killing me as to what exactly went wrong. And as someone living in The Netherlands I'm also kind of mad at the apparent fragility of this huge chunk of our infrastructure. If this had happened on a work day, it would have been a real national emergency, rather than just a huge national inconvenience. I would appreciate one of those post-outage "what happened" reports like with the AWS and Facebook out…
From the notice: > It affected the system that generates up-to-date schedules for trains and staff. ...boy oh boy did trying to look into what NS uses for crew scheduling ever send me down a rabbit hole. I don't know if the systems have changed but while poking around online I found this[1] doc about the Netherlands' timetable revamp around 2006 and it talks about the complexity of TURNI-- their on-the-fly crew sched…

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

I have seen “SAP” tossed around in this industry and still have no clue what they do to earn money. Are they the equivalence of “salesforce”?
They're absolutely colossal in size
My ex-girlfiend's father is an engineer there in Baden-Wurttemberg - I'd characterise them as closer to something like Oracle rather than Salesforce

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

No, it’s talking about crew scheduling/allocation , not signaling. The signaling system is totally fail safe. Even if that system totally went out, drivers are required to know where all the signals are, and to treat an unlit signal as a red.
What if the failure lit all the signals in green?
