Trolleybus In 1939, due to poor economic situation throughout the interwar period and the city's growing population, a trolleybus line began operation, partially replacing the original tram network. During the Second World War the cars were mainly driven by women. The trolleybus network consisting of 4 lines was decommissioned on 31 July 1971. Rail Olsztyn has train connections to various major cities in Poland, including Warsaw, Kraków, Gdańsk, Szczecin, Poznań, Bydgoszcz, Białystok, Wrocław, Łódź, Toruń, and various towns in the region, including Elbląg, Iława, Działdowo and Ełk. Olsztyn Główny is the main railway station in the city. Plans exist to demolish the building and replace it with new infrastructure, contrary to previous information about the current building being renovated. Tram Historically, the city's first tram line was built in 1907 and gradually expanded over the years. It ceased operation in 1965. In 2006, authorities considered the reintroduction of trams in the city to address transport problems and subsequently concluded feasibility studies on the matter in 2009. An long tram network was built between 2011 and 2015. The contract was signed in 2011 and construction commenced in 2012. It was a first new tram system built in Poland in 55 years; 15 low-floor Tramino trams were ordered from Solaris in September 2012. There are three tram lines in operation. A long extension is planned and Turkish manufacturer Durmazlar had been selected to supply 24 trams for the network.
