route length of 178km. Between Monday to Friday, the network runs routes using ca. 200 vehicles. At 22.55km, line no. 21 is the longest on the network, with line no. 38 being the shortest, measuring a total length of 1.35km. Depots Silesian Interurban trams are positioned across four depots, each serving a respective area of the network: area 1 Będzin, area 2 Katowice-Zawodzie, area 3 Bytom-Stroszek and area 4 depot in between Gliwice and Zabrze. The depot in Zawodzie opened in 1962, after a closure of the Katowice depot. In 1968, Bytom's depot at Piekarska street was decommissioned, and a new depot was built in Stroszek at the end of a new line. Subsequently, the depot in Rozbark (a district of Bytom) was closed from which all of the equipment was moved. Zabrze and Gliwice got their new depot in 1972, while Będzin benefited from a brand new depot in 1978. In 2006, a decision was taken to stop using the Chorzów Batory depot for line traffic. Between 15 June and 12 August the service was gradually transferred to other depots, while the Chorzów Batory depot became a maintenance depot. Chorzów Batory depot was subsequently renamed to ZUR (Tram Repair Facility, ). Corporate Ownership and structure Prior to January 2019, KZK GOP was the transport authority in Silesia. On 1 January 2019, a metropolitan transport authority was established also known as the ZTM, thus Tramwaje Śląskie became a carrier operating on behalf of ZTM. Passenger numbers In the steam era, the network recorded 3.6 million passengers in 1898. In 1900, the network recorded 7.6 million passengers. After World War II, the passenger numbers gradually increased year on year, and in the 1950s, the numbers stabilised at 300 million passengers per year. In 1983, the network saw record passenger numbers – 353 million. Since 1983, passenger numbers have fallen each year, however detailed passenger numbers are not readily available for recent years.
