Train drivers at Germany’s national railway Deutsche Bahn have begun a 24-hour strike, according to the GDL trade union, which represents the drivers, writes DW.

The nationwide passenger carrier strike started at 10 p.m. on Thursday and was set to continue until 10 p.m. on Friday. It is expected to cause thousands of train cancellations, with delays and disruptions set to continue through the weekend.

A freight strike began at 6 p.m. Thursday. The strike is affecting long-distance and regional trains, as well as commuter trains in the cities of Berlin and Hamburg.

The strike is the fourth to hit Deutsche Bahn this year and comes on the heels of a 20-hour GDL work disruption that forced the cancellation of nearly 80% of all long-distance and regional trains in Germany on November 15-16.
