Cancelled CNL457 in Koln Hbf, displayed on platform board, Koln, Nordrhein-Westfalen, Germany, 2015

I was in Koln to catch the CityNightLine train 457 for Prague. However, this was my first ever rail trip across Europe when there was ever a problem. My trip back coincided with a national rail strike in Germany, which meant that they had to put us up in hotels after CNL457 was cancelled without warning late at night, as seen by the departure time on this platform board, but not by any notice of cancellation, as there was none.
