Narrow Gauge Railways In Bulgaria
From the 19th into the early 20th there were many and gauge railways in existence Bulgaria, some were dismantled and others were Gauge conversion, converted to standard gauge. Septemvri–Dobrinishte The picturesque Septemvri–Dobrinishte narrow-gauge line is 125 km long and features many tunnels, bridges, Spiral (railway), spiral loops and last but not least the highest railway station in the Balkans, namely Avramovo, Blagoevgrad Province, Avramovo Station situated at 1267 m altitude. The line is still used for regional services by no less than 5 pairs of diesel-hauled trains per day as of the 2011 Timetable. There are a couple of preserved steam locomotives, but as of 2010 only 609.76 is operational and occasionally hauls tourist trains along the line. There are plans for restoration of the other preserved engines, but when would this happen is still unclear. Other railways Other examples in Bulgaria include the children railways in Plovdiv and Kurdzhali and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Locomotive Sofia
Steam is water vapor, often mixed with air or an aerosol of liquid water droplets. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Saturated or superheated steam is invisible; however, wet steam, a visible mist or aerosol of water droplets, is often referred to as "steam". When liquid water becomes steam, it increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into work (physics), mechanical work by steam engines such as reciprocating engine, reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the Industrial Revolution and modern steam turbines are used to generate more than 80% of the world's electricity. If liquid water comes in contact with a very hot surface or depressurizes quickly below its vapor pressure, vapour pressure, it can create a steam exp ...
