I think it (the corpse) was around Dortmund, but the train I was on was somewhere to the west. This was a while ago, and may even have predated the faster Cologne-Frankfurt line.

On the same line, somewhere between Bonn and Cologne I think, we once stopped for a while, and then proceeded slowly because of children playing by the tracks. The announcement?

Wir bitten um Ihr Verständnis, und hoffen dass wir keine erwischen.
