"To stabilise services, BVG is deploying additional replacement buses," the company added. Buses are running on line 62 between the Mahlsdorf and Köpenick S-Bahn stations and on line 50 between Französisch-Buchholz and the Pankow S-Bahn station. BVG suspended all tram services on Monday due to icy overhead lines caused by freezing rain. The overhead lines must be laboriously cleared of ice by hand. For this reason, the lines are only gradually returning to service. The BVG has not yet provided a forecast as to when full service will resume without restrictions.
