The Słupsk trolleybus system was a trolleybus network operated by MPK Słupsk in Słupsk, Poland, from 1985 to 1999. The system measured at the most 19.1 km on three lines. The first trolleybus projects in Słupsk date back to the 1930s, when one trolleybus line was planned. It was to connect Kobylnica with Brusków Wielki. This plan was not implemented. At the end of the 1970s, the voivodeship transport company WPKM Słupsk developed a project of Słupsk trolleybus system. The plan assumed the construction of five trolleybus lines, including one to Ustka, 18 km away from Słupsk. First construction works began in April 1985. More information...
