German rail travellers face heavy delays in the run-up to Christmas. Workers went on a nationwide four-hour strike, with all long-distance trains cancelled. It comes after salary talks broke down last week.
Services slowly resumed after 9 a.m. but disruptions are set to continue throughout the day, rail operator Deutsche Bahn said.
Although no additional rail strikes have been announced yet, EVG warned that further warning strikes can be expected during the pre-Christmas rush.
A separate union, the Union of German Locomotive Drivers (GDL), is expected to continue its parallel talks with DB but warned that its 36,000 members could also take action if wage negotiations talks fail.
