Warning strike: Buses and trains remain in depots in many places. Millions of passengers are affected.

Almost all major NRW local transport companies such as KVB (Cologne), Rheinbahn (Düsseldorf), DSW21 (Dortmund) and the Münster municipal utility are on strike. Only a small part of the public buses run in the strike regions, which are already operated by private subcontractors. The background to the warning strike is collective negotiations that began in January about working conditions in the municipal transport companies.
