The standard-gauge network comprises a double-track north-south line from the city's main railway station to Kanta in the district of Jaroty, with two short single-track branches, one serving the University of Warmia and the other serving Wysoka Brama in the city centre.
Currently services are only operating on Line 1 from Kanta to Wysoka Brama. Line 2 from Kanta to the main station will begin operating on December 27, while Line 3 services from Kortowo to the main station will start on December 31.
Services are operated by a fleet of 15 29.3m-long three-section bidirectional Solaris Tramino S111O LRVs. Each vehicle accommodates more than 230 passengers, 36 of them seated.
The €105.3m project was 85%-funded by the European Union through the European Regional Development Fund (ERDF).
