Thumer Netz

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 was a connection to the Annaberg-Buchholz - Flöha railway (Zschopau Valley Railway), and in Meinersdorf was a connection to the Chemnitz–Aue–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 Erzgebirge, 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.
