I wonder if people think they will be taken seriously with so much hyperbole and drama

> Only then I notice: the driver has been speaking German only.

Oh wow a German conductor in a German train speaking German oh how awkward...

No you were not "kidnapped" your train just stopped at a different station.

> “That’s a different federal state.”

Yes and if you go to many cities in Europe and the US you can walk from one country to another. Oh wow shocking I know /s

Of course this is Deutsche Bahn at its best (in getting hand and feet mixed up) and that compensation is ridiculous. It should at least get your ticket back to the place you intended to go.

Neuwied to Troisdorf is 1h by car or train (in a good day of course)
