are tram networks in both Bratislava and Košice. The first trams in Bratislava started operation in 1895, and there are currently 5 lines in service with a track length of 41.5 km. A newest tram line was built across the river Danube to the Petrzalka suburb on the right bank. There are multiple plans for expanding the network, but funding is currently unclear. Košice started operating trams in 1914, after wagons pulled by horses and a steam tramway. Trams currently run over 34 km of tracks and run on 7 lines within the city and 8 fast tram lines to U. S. Steel Košice. Spain In Spain, modern tram networks have been opened in Alicante, Barcelona (Trambaix and Trambesòs), Bilbao, Madrid, Murcia, Parla, Santa Cruz de Tenerife, Seville, Valencia, Vélez-Málaga, Vitoria-Gasteiz and Zaragoza. Jaén had built a tram network in 2011, but it only operated for a short period. Sweden The most extensive network in Sweden is in Gothenburg with a total track length of 90 km double track. Gothenburg started with the Horse Tramway in 1879 and over the years the tramway has expanded into the Nordic region's largest tramway system. Stockholm had horse-drawn trams from 1877; however, the large tram system began to be abandoned and removed in 1957, with the last tram running in September 1967. Presently Stockholm has four lines on three non-connected systems owned by Storstockholms Lokaltrafik: Spårväg City; Lidingöbanan; Nockebybanan and Tvärbanan. There are plans for future extensions and two projects are in active development. Norrköping has an 18.7 km tram network consisting of two radial lines, which was extended by 5 kilometres in 2006–2011. Lund inaugurated its first ever tram line on the 12th of December 2020. At a length of 5.5 kilometers, it connects Lund Central Station with the new urban development at Brunnshög and the research facilities MAX IV and ESS. A single-track heritage line has operated in Malmö since 1987, after the last "real" tram line closed in 1973. City officials decided in October 2008 that the city should have at least one light rail line operating before 2020, and up to six lines after that. A combined tramway museum and heritage tramway is located at Malmköping, Södermanland County, maintained by Svenska Spårvägssällskapet, the Swedish Tramway Society. Switzerland The first tram in Switzerland began operations in 1862 in Geneva. The tram, which was initially horse-drawn, got converted to steam in
