Hat tip Delta21
It is really unlikely German trains allow more people on board than seats and seat belts for safety reasons.
What is sad about her is no 16 year old can be this spoiled in public without adults encouraging her.
I have travelled extensively by train in Europe for years. I can’t recall seeing a set belt.
The one time I did see people sitting in the aisles of an overcrowded train was out of Fankfurt. Spring break had just started and kids were headed to Britain. The train was so crowded that my wife and I could not get to our first class seats. I sat in the aisle on our luggage.
During that trip we never saw anyone to check our tickets and border customs did not bother to check passports on the borders.
Deutsche Bahn (DB) is extremely efficient. They do not oversell intercity trains, the confusion would delay the train and impact other trains which is unacceptable, unless it is a weather/safety delay. The S-Bahn commuter trains are another story. while generally on time, you will get up close and personal with perfect strangers during high demand times.
Commuter and regional trains generally have no seat belts. I traveled on a high speed train from Frankfurt to Stuttgart last summer and do not recall seat belts there either.
Diesel burning train? Not in Germany.
Seat belts in trains? Nope.
Anyone with a ticket can board, if you haven’t reserved a seat in advance you can end up without one.
I wonder how much energy was needed to ship those bananas to northern Europe.
