Bus transport in Warsaw was introduced in 1920. Since 1994, services have been managed by ZarzÃÂ d Transportu Miejskiego w Warszawie (ZTM Warszawa), and operated by various companies under contract.
In 1920, a decision was made to establish the Bus Division within the Warsaw Tramways. Initially, the routes were served by Saurer double-decker buses.
During the defense of Warsaw in 1920, buses were used to transport troops. By the end of 1921, there were five bus routes in operation, but as new tram lines were built, these routes were quickly phased out in favor of trams. The bus service was also unprofitable. In 1925, the last Line 3 was discontinued, and for four years, city buses disappeared from the streets of Warsaw.
The buses were reintroduced in 1928. In the late 1920s, many new routes were introduced (by September 1939, there were up to 23 regular lines), and a new bus depot was opened on à Âazienkowska Street. In 1938, modern bus stop signs were introduced. Before the outbreak of World War II, Warsaw had 180 buses.
During the first days of Siege of Warsaw in September 1939, bus service continued without major changes. On September 6, bus service was suspended. Following Roman UmiastowskiâÂÂs radio appeal calling on men capable of fighting to leave Warsaw, approximately 80 buses departed the city. The remaining fleet, which had not been damaged by shelling or bombing, was used by the military for transport and support purposes.
Bus service was restored on 3 October 1939, initially on the route from Teatralny Square to Savior Square. Over the next dozen or so days, additional routes were launched, though their sole purpose was to replace the trams until the tram network could be rebuilt.
As of 2022, there are 302 bus lines in Warsaw and the surrounding areas, covering 4548 km.
There is one ticket tariff for every mode of transportation. Tickets can be purchased at ticket machines all over the city and online.
The Warsaw bus network comprises 1810 vehicles, including 162 electric ones and 70 hybrid ones.
In November 1994, the first German low-floor Neoplan N4020 was put into operation. 1999 was marked by modern and low-floor Solaris Urbino 15 buses. In 2002, MAN buses joined the Solarises.
In September 2025, MZA signed a contract with Solaris for electric buses. In January 2026, MZA exercised an option to extend its September 2025 order with Solaris by bringing 79 additional electric buses. The expansion includes 50 articulated Solaris Urbino 18 electric buses and 29 Solaris Urbino 12 electric buses, bringing the total order to a further 158 zero-emission vehicles.
