The German Machinists’ Union (GDL) commenced a three-day strike after unsuccessful collective bargaining talks with German Railways (DB). The strike, impacting freight and passenger services, caused significant disruptions across various routes. Major hubs like Berlin and Cologne faced flight disruptions, while the normally bustling Cologne central station stood deserted. The strike is set to persist until 18:00 on Friday, January 12, affecting rail operations until then.
