Bedia diesel locomotive – idling

About the sound

The sound of a stationary diesel locomotive idling in front of the coalmine entrance. It is a special version of a typical mine locomotive used for the transportation of people and material. It is adapted for operation on the steeply sloping underground tunnels with the help of a rack and pinion system. The locomotive was manufactured by Bedia in Bonn, Germany, in 1989. The engine output is 130kW. In recent years it has mainly been used for transporting sand being taken into the mine to fill the tunnels as part of the closing down process of the coal mine.

The sound was recorded in the Trbovlje-Hrastnik coal mine which has a long tradition. The first mine in the Trbovlje area, founded by the entrepreneur Franz Maurer from Wiener Neustadt, Austria, started to operate in 1804. It was later followed by several smaller mines. The arrival of the Austrian Southern Railway to the Zasavje region in 1849 was a double gain: it facilitated the transport of coal to clients whilst simultaneously the railway itself was a major customer itself, having a great need for coal. In 1873 all the coal mines in Zasavje were merged under Trboveljska Premogokopna Družba (Trbovlje Coal Mining Company) which remained the proprietor until WWII. After 1946 all coal mines were nationalised by the new socialist authorities. Zasavje coal mines reached their peak of production and technological development in the second half of the 20th century. After 1991 coal was no longer considered the energy source of the future, and so the state decided to gradually close the mine. The extraction of coal ceased in 2010 and the company focused exclusively on closing it down which should be completed by 2018.
