The Schwarzbach railway (German: Schwarzbachbahn, pronounced [ˈʃvaʁtsbaxˌbaːn] ⓘ) was a 750 mm (2 ft 5+1⁄2 in) Saxon narrow-gauge railway in Saxon Switzerland.

Since 1995 the Schwarzbachbahn Society has endeavoured to rebuild a section of the line and run it as a museum railway.

The former station ins Lohsdorf has been redecorated and new tracks laid there, which should reach Ehrenberg until 2026.

The society has its headquarters in the station building at Goßdorf-Kohlmühle.

Permission for the reconstruction of the railway between Goßdorf-Kohlmühle and Lohsdorf has been refused by the authorities, fearing damage to the environment.
