Chaos in Berlin's public transport. Or: How a 60 minute connection turns into a 100 minute problem. This morning, in just these 60 minutes, we've had delays due to a previous delay, due to construction, due to the track being occupied by another train, due to a medical emergency, due to a train having been cancelled, and due to a signal failure. This is the daily experience of patiently suffering Berliners. No wonder students frequently are late to lectures. I might be, too.
