Bulgarian railways: Trainspotting on Sofia - Pernik line

Sofia - Pernik railway line via Vladaya passage is a part of the international line to Greece. And this is one of the most busiest single track sections in Bulgaria. In the autumn 2016 due to a heavy derailment and badly damaged track on the other freight-only line to Pernik (via Voluyak and Razmenna) the line through Vladaya passage become definitely the busiest railway line in Bulgaria. Also because of the poor condition of the line and the heavy ascents and descents (reaching 25-26/1000 m) the freight trains were limited to 600 t. So, that is the reason for the tiny freight trains on the video. They are tiny, but instead of this they are many. Private railway operators are also represented by TBD Tovarni prevozi and BZK (Bulgarian Railway Company).
