Silesian Trams () is one of the largest tram systems in the world and the largest and longest tram system in Poland, located entirely within the Silesian Voivodeship. Started as a part of the German Empire in 1894, the system currently has 677 stops across 29 lines and serves the region’s population inhabited by more than two million people. Silesian Trams is at the heart of a region known for its dense historical and current industrialisation (coal, coke, steel and other industries).
Due to the deindustrialization since the 1990s and subsequent lack of investment, several branches were decommissioned in waves. The system runs on a mixture of on-street track shared with other traffic and reserved track sections segregated from other traffic. The network is spread over more than 50 kilometres (east-west axis) and covers twelve towns in the Metropolis GZM of southern Poland: Katowice, the capital town of the region, Bytom, Chorzów, Mysłowice, Ruda Śląska, Siemianowice Śląskie, Świętochłowice, and Zabrze in Upper Silesia, as well as Będzin, Czeladź, Dąbrowa Górnicza, and Sosnowiec in the Dąbrowa Basin. Until 2006, trams also frequented Piekary Śląskie and Wojkowice, and until 2009 trams ran through Gliwice (trams still run to the depot at the border of Gliwice and Zabrze where passengers can switch to buses).
Tramwaje Śląskie is operated by a mixed fleet of modernized Konstal 105Na, Düwag and Lohner trams and brand new Pesa Twist trams. In recent years, the network benefited from investments from the European Union. Rolling stock was modernized to include low-floor cars and multiple track sections were upgraded. Recently, two major investments since cutbacks have been approved to extend the network length. A new section opened in December 2022 in Zagórze, Sosnowiec, and an investment on an connector track between Chorzowska and Gliwicka streets in downtown Katowice is being carried out.
History
Steam trains and early electrification
Initially planned as a metre-gauge, the system was established by German Empire in 1894 as a unique narrow gauge steam interurban railway.
The first line was 36.5 km long and connected Gliwice with Piekary Śląskie through Zabrze, Chebzie, Chorzów and Bytom, another connected Katowice and Siemianowice. After four years, in 1898, Kramer & Co. was chosen to start electfication on Katowice Rynek (Kattowitz, Ring) - Zawodzie line, after which Schikora & Wolff completed electrification of four additional lines. In 1912, the first short line was built in Katowice. In 1913, a separate standard gauge system connecting Bytom with suburbs and villages west of the town was launched.
Post World War I
After World War I and the Silesian Uprisings, in 1922 the region (and the tram network) was divided between newly independent Poland and Germany, and international services appeared (the last one ran until 1937). In 1928 further standard gauge systems were established in Sosnowiec, Będzin and Dąbrowa Górnicza (the so-called Dabrowa Coal Basin - a region adjoining the Upper Silesian Coal Basin).
Between 1928 and 1936 most of the original narrow gauge network was converted to standard, which allowed a connection with the new system in Sosnowiec. By 1931, 47,5% of the narrow-gauge network was reconstructed, with 20 km of new standard-gauge track built.
During World War II, the German authorities decided to merge all the systems and administrations and they have remained as one united network to the present day (though the old boundaries are still easily traceable).
In 1951, the tram system was taken over by a state-owned company WPK Katowice and until the 1970s it was widely extended and partly modernised reaching its maximum length at the end of the 1970s (ca. 235 km). The last and only remaining narrow gauge line was decommissioned in 1952 between Siemianowice Śląskie and Chorzów. Since the late 1960s, the classic rolling stock has been replaced by modern cars based on PCC streetcar technology.
In the 1980s some of the non-modernised, rural lines were abandoned (the longest one from Bytom to Wieszowa with a branch to Stolarzowice). Between 1976 and 1986, the first wave of tram line decommissioning began in Silesia. Six lines in total were decommissioned in a ten-year period. Aging tram cars and infrastructure as well as dwindling passenger numbers saw passengers switch to buses. In addition, the future of a seventh line was being contested. In 1979, line no. 38 was suspended in Bytom, however it returned to service on 10 February 1982 after citizens of Bytom petitioned for the line to reopen.
