The Kobrinskaya narrow-gauge railway is located in Kirov Oblast, Russia. The forest railway was opened in 1946, has a total length of 80 kilometres and is operational as of 2014, the track gauge is 750 mm and operates year-round.
Given land type and the materials that seem to be at hand (cheap)… that is pretty good looking track work. Athough the ties look to be rather randomly placed I think it is well maintained. I have seen lots worse Standard Gauge tracks here in the U.S.!
