A union representing German train drivers on Wednesday called its members to strike for 24 hours this week, following the breakdown of talks with the main national operator in what is shaping up to be an unusually difficult dispute over pay and working hours. The GDL union said the strike will affect passenger services operated by state-owned Deutsche Bahn from 10 p.m. on Thursday until 10 p.m. on Friday. Freight trains will be hit from 6 p.m. Thursday.
