If you’ve travelled with German Rail, odds are that you’ve encountered the time unit known as “Deutsche-Bahn-Minute” (DBM). As a frequent traveller, you know that five DBM’s can mean basically anything from “right on time” to “the train is still stuck in Narnia”. Consequently, it should be taken with a pinch of salt when an official statement reads that changing trains will only add five minutes to the total length of your trip.
