There was a failure at the ‘traffic control centre’ in Amsterdam this morning. It took me almost four hours to get to work; and being stranded at Utrecht Centraal (34 km south of my workplace) for a good forty minutes and sitting in traffic on the replacement bus from Naarden-Bussum didn’t help either.
The entire rail network of the Netherlands is, according to Wikipedia, controlled from just thirteen control centres. Closing small signalboxes because they’re cute and you want to be evil is all well and good but the effects if something goes wrong spread like wildfire.
