Traveling by train in Germany is great, but it also an endless pandora box of adventures, specially during weekends.

The 9 euro ticket is a nice idea, how well it holds on, even on long period depends on improving the infrastructure.

Just today I took almost 3h to what I usually do in 30m with the car over the motorway.

Yep 2h 30m extra by taking the 2x bus + train + subway + waiting times instead of the car.
