I find it utterly fascinating that steam locomotion still exists in the 21st century. After my foray into China in 2015 to photograph steam, Bosnia was also a must to capture the last of the world's steam engines. In this scene, Kreigslok locomotive, 33-503, is seen shunting empty coal wagons at Dubrave coal mine. The class 33, "Kriegloks" locomotives, were mass produced during the Second World War in Germany with around 7000 manufactured as part of Hitler's war machine. A 2-10-0 wheel arrangement, the German translation literally means "War Locomotives". It was the most important locomotive in service during the war with the design kept as simple as possible. Amazingly, these 70 year old steam locomotives are still working to this day in Tuzla in Bosnia Herzegovina, having been acquired by Yugoslavia from the Soviet Union in the 1960's and eventually passed on to the coal mines at Tuzla. A total of five still survive with three in service, mainly for shunting duties.
