Exercise is healthy, even on business trips.
Perhaps such care brought Deutsche Bahn to a new fitness idea: running training in a two-part train with the destinations of Hamburg and Binz.
Just tested in Leipzig: There, the ICE 1600 is almost ready to depart and everyone has boarded when an announcement from the train manager startles the passengers.
Unfortunately, the carriage sequence is displayed incorrectly, the Hamburg part of the train actually goes to Binz and vice versa.
The train parts would only be separated in Berlin.
If you want, you can remain seated and only change cars in the capital.
Everyone else can go out again, sprint a few meters across the platform and get back on.
"I'll wait a minute for that," the train driver cheers.
If you are hoping for a continuous seat to work in the direction of Hamburg, you can easily do it.
But that's not all: as soon as you've gotten back to Wittenberg and your heart rate is resting, brain jogging is the order of the day.
"It's just easier to swap car numbers, it's just been decided," announces the conductor.
That means: Whoever sprinted in Leipzig should return to the original part of the train in Berlin – that one is now going back to Hamburg, the other to Binz.
Didn't get it right away?
It doesn't matter, the train driver goes through it again, gets muddled, then capitulates: "I don't know how to explain it to you anymore." But the good, sporty idea is still popular.
The laptops close again - and we head straight through the hustle and bustle on the Berlin platform into what we hope is the right car.
An obstacle course from front to back, past people and suitcases.
At the destination, in the on-board restaurant, the joy of a seat, cappuccino and the contribution of the train to the good pedometer balance is great.
The only thing she still has to work on is fair play: the foreign passengers were clearly at a disadvantage – all announcements about the Sprinter Games were made in German.
