The Transylvanian Mining Railway was a local interest narrow-gauge (760mm gauge) railway which was the first mining railway in Transylvania. This railway was built to ease the transportation of the iron ore mined from the iron ore mines from Ghelari to the blast furnace in Govăjdia and the ironworks from Hunedoara. This railway was also known as the "Hunedoara-Ghelari Local Interest Railway", "CFI Hunedoara", "Mocănița Hunedoara", "Calea Ferată Minieră Ardeleană", "Erdélyi Bányavasút" in Hungarian. The line was 10km (6.2mi) long from Hunedoara to Govăjdia and another 6km (3.7mi) from Govăjdia to the Retișoara terminus. This line was used by mixed trains that carried both iron ore and passengers from Ghelari to Govăjdia and Hunedoara's ironworks. They also transported dolomite and limestone from the limestone quarries near Govăjdia to the ironworks.
