The Czech Export Bank will loan the Serbian government Euros 120 million for the project, which involves electrification and upgrading of infrastructure for 120km/h operation. The 40km Niš - Dmitrovgrad line is Serbia's only direct rail connection with Bulgaria. It forms part of the 161km southeastern branch of Pan-European Corridor 10, which links Austria and Hungary with Greece and Bulgaria. The line is the only section of Corridor 10 within Serbia still to be electrified.
