Originally it ran from Sibiu railway station to Sighișoara[2] in Mureș County.

As the line originally lay within Hungary, the Hungarian State Railways operated services until 1919, when Transylvania became part of Romania.

CFR then continued to operate services until 1965 when the original section from Sighișoara to Agnita was closed.

After threats from CFR Infrastructură that track would be lifted all the rail infrastructure became protected as a historic monument in 2008.

Currently there is an active project called Asociația Prietenii Mocăniței ("Friends of the Narrow-gauge railway") and aimed at restoring the line for tourist operation; it operates occasional tourist steam trains on parts of the line.
