In more than 80 cities there have been almost no buses, subways and trams running since the early hours of the morning. Only a few buses, which are already operated by private subcontractors on public transport routes, can run.

Rail transport such as regional trains, S-Bahn and ICE trains are not affected by the warning strike. The Verdi union has called on around 90,000 employees in more than 130 local public transport companies nationwide to go on warning strikes. Further warning strikes are only completely ruled out in federal states where higher wages are being negotiated.
