Silesian Interurbans

Silesian Interurbans (Polish: Tramwaje Konurbacji Śląskiej), one of the largest tram (streetcar) systems in the world, has been in existence since 1894. The system is spread over more than 50 kilometres (east-west axis) and covers thirteen towns in the Upper Silesia metropolitan area (Southern Poland) and their suburbs (Katowice, the capital town of the region, Będzin, Bytom, Chorzów, Czeladź, Dąbrowa Górnicza, Gliwice, Mysłowice, Ruda Śląska, Siemianowice Śląskie, Sosnowiec, , and Zabrze, until 2006 also in Piekary Śląskie and Wojkowice), which is densely industrialised (coal, coke, steel and other industries; though decreasing since the 1990s) and inhabited by more than 2 million people.

The system was established by German Empire in 1894 as a unique 785 mm (2 ft 6 ²⁹⁄₃₂ in) 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) electrification started. In 1912 the first short 4 ft 8 ¹⁄₂ in (1,435 mm) line was built in Katowice. In 1913 a separate standard gauge system connecting Bytom with suburbs and villages west of the town was opened. After World War I and the Silesian Uprisings 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 another standard gauge system was 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 (although the last narrow gauge line, Siemianowice Śląskie-Chorzów, remained till 1952), which allowed a connection with the new system in Sosnowiec (a service between Chorzow and Sosnowiec through Katowice was established in 1931).
