Torn tram overhead line in Warsaw's Mokotów reroutes four tram lines on 5 November 2026

What happened

A break in the overhead traction line at the crossing of Puławska and Woronicza streets in Mokotów disrupted tram services on the morning of Thursday, 5 November 2026. The Warsaw public transport authority (ZTM) said the damage changed the routes of trams on lines 4, 10, 18 and 31 in both directions. Lines 4 and 10 run along Puławska, Rakowiecka and Wołoska streets to the Woronicza loop. Line 18 follows the same detour and then returns to its regular route, while line 31 uses Wołoska and Woronicza streets to reach the Mokotów depot (Zajezdnia Mokotów).

Replacement bus service and outlook

ZTM launched a replacement bus service marked with the letter Z, called 'Za Tramwaj'. The buses run from Metro Wilanowska 02 via Puławska, Waryńskiego and the Jazdy Polskiej roundabout to DS Riviera 01. Passengers in the district were advised to allow extra time and check the changes when planning journeys. Sources do not say how long the disruption will last. Technical services are working to remove the fault, and no restoration time has been given yet.
