Bulgarian State Railways locomotives 142-150

Bulgarian State Railways locomotives 142 to 150 were the two-cylinder 0-6-0 mixed-traffic locomotives with six-wheeled tenders that supplemented the original fleet on Bulgaria's first railway, which opened in 1866 to connect Ruse on the Danube with Varna on the Black Sea. Ten were ordered from England shortly after the line opened: eight were built by Sharp, Stewart and Company in Manchester and two by Beyer, Peacock and Company, and all were delivered between 1868 and 1869. They passed to the Chemins de fer Orientaux in 1873 and to the Bulgarian State Railways in 1888, and were withdrawn in 1914. One, number 20, later 285 and then 148, is displayed at the National Transport Museum in Ruse.
