[1] The impulses for the creation of the system were the general electrification of the city and an industrial and craft exhibition planned for 1912.
The line ran from the railway station, through the city center, to the end of the present Piłsudskiego Street.
In the years 1922–1924, due to an economic crisis, trams were suspended.
The second line was created in 1925 and ran along the current Zwycięstwa Street to Rokosowo (the new section was 2.8 km long).
The third line started to operate on July 1, 1913, after the bankruptcy of the local railway from Uniescie to Koszalin (launched in 1905).
