Warsaw Trams and Buses Compilation 

Public transport in Warsaw includes buses, trams (streetcars), Metro, light rail Warszawska Kolej Dojazdowa line, urban railway Szybka Kolej Miejska and regional rail Koleje Mazowieckie (Mazovian Railroads). The buses, trams, urban railway and Metro are managed by the Public Transport Authority (ZTM). Koleje Mazowieckie and WKD are owned by Masovian Voivodeship. There are also some suburban bus lines run by private operators. Until 1994, the Warsaw Communication Company (Miejskie Zakłady Komunikacyjne, MZK) was responsible both for the technical service of vehicles (trams and buses) and for the organization of transport (tickets, timetables, routes). In 1992, the Public Transport Authority was established and became responsible for the organization of transport, while in 1994 the MZK was divided into Warsaw Trams (Tramwaje Warszawskie, TW) and Warsaw Bus Company (Miejskie Zakłady Autobusowe, MZA), responsible for technical maintenance of trams and buses, respectively.
