Rail traffic in Serbia - old southeast railway line Niš - Dimitrovgrad - diesel powered freight [4K]

The recording was done on the specific railway line between Niš, Pirot and Dimitrovgrad. Some scenes were taken in the Sićevo gorge, under trains and railway tunnels portals and on steel bridges over the river Nišava. Special video and audio attention is paid to the blending of this train traffic into the surrounding nature and the sounds of nature. The calming sounds of birds on the surrounding trees are disturbed by the arrival of diesel powered heavy freight trains, while trains gradually climbing from Niš to the Serbian / Bulgarian border. Diesel powered heavy rail traffic at old Southeast European freight rail corridor... Old EMD, Russian and Czechoslovakian diesel locomotives with variety of freight trains... Occurrence of local passenger trains in occasional breaks between a lot of freight trains...
