The Šargan Eight is a narrow-gauge heritage railway in Serbia, running from the village of Mokra Gora to Šargan Vitasi station. Modern line was restored on 1 September 2003. An extension to Višegrad in the Republika Srpska, Bosnia and Herzegovina, was finished on 28 August 2010. It was planned to extend the railway to the village of Kremna by the end of 2011, and in 2013 to extend to the city of Užice, but this was only partially carried out.
