Thum

The Thumer Netz was a narrow gauge railway network in the area around Thum in Saxony, Germany that operated from 1886 until 1975. It had a 750 mm (2 ft 5+1⁄2 in) gauge. Total length was about 44 km (27.34 mi). This network had three segments that connected three standard gauge stations: In Wilischthal and Schönfeld-Wiesa were connections to the Annaberg-Buchholz-Flöha railway, and in Meinersdorf was a connection to the Chemnitz–Adorf railway. The three segments had their hub in Thum. This set of railroads brought much-needed connectivity and transport capacity to the small towns and villages of the central Ore Mountains, which had formed a viable industry in the 19th century due to abundance of water power, wood, ore and other natural resources as well as cheap labour. A landmark was the 180 m (590.6 ft) long and 35 m (114.8 ft) tall Greifenbach viaduct between Ehrenfriedersdorf and Geyer.
