ŽS (Železnice Serbije; Serbian Railways) Bo-Bo diesel locomotive 641-331 has just arrived at Niš with train 7830 from Kuršumlija. Note the attached wagons.
This service, and its outward working, had stopped running between Kuršumlija and Kosanička Rača a few days earlier on 14 May, reportedly due to the condition of the track. Services restarted a few weeks later.
