Kosovo Polje
Trainkos operates of railway in Kosovo, of which serve both freight and passenger and only serve freight traffic. The non-electrified network originally consisted of two lines crossing at Kosovo Polje railway station in Kosovo Polje: A main line going from Kraljevo in western Serbia via Mitrovica and Kosovo Polje to Skopje in North Macedonia, and a branch line in east-west direction from Niš in southern Serbia via Pristina railway station in the capital Pristina and Kosovo Polje with one branch leading to Peć and the other one to Prizren. Of these lines, the one from Pristina to Peć and the one from Kosovo Polje to Macedonia are still served by passenger trains. Some more parts of the network are occasionally served by freight trains, like Kosovo Polje - Obilić; the other parts of the network are currently unused. For years, there have been plans to extend the branch to Prizren across the border to Albania, to create a link to the network of the Hekurudha Shqiptare. However, these projects are no more than letters of intent.
