Germany is facing transport chaos as train drivers begin a four-day strike.
The state-owned rail operator Deutsche Bahn is taking legal action against the drivers’ union in a bitter dispute.
The row is over terms of contract negotiations and a claim for a six percent pay rise and a shorter working week.
One commuter said: “I have the impression that all of Germany is being taken hostage for six percent more pay. I find that highly exaggerated.
The dispute is threatening to disrupt celebrations this weekend for the 25th anniversary of the fall of the Berlin Wall.
If it continues, the four-day strike will be the longest in the history of Deutsche Bahn.
