context_page_description: The Transylvanian Mining Railway was a local interest narrow-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", "Mocăniţa Hunedoara", "Calea Ferată Minieră Ardeleană", "Erdélyi Bányavasút" in Hungarian. The line was 10 km long from Hunedoara to Govăjdia and another 6 km from Govăjdia to Retişoara terminus. This line was used by mixed trains that carried both iron ore and passengers from Ghelari to Govăjdia and Hunedoara's ironworks. They've also transported dolomite and limestone from the limestone quarries near Govăjdia to the ironworks.
context_section_description: There are three tunnels on the line:
  The first tunnel is at 5 km from Hunedoara, it is a 747 m long straight tunnel. The construction of this tunnel started in 1888 and lasted 12 years. The tunnel was designed by two Italian engineer brothers. The digging of the tunnel was started by two teams on both sides of the mountain and meeting in the middle in 1894. The finishing work lasted another 6 years till the line opening in 1900. The tunnel is passing through solid limestone uniting Zlaşti valley to Govăjdia valley, with a maximum incline of 27‰ from Zlaşti. The entrances and some sections of the tunnel's inside were lined with stone, other sections had the sidewalls lined with concrete with the ceilings lined with brick. Some sections of the tunnel have bare rock walls where reinforcement wasn't necessary. There are sections in the tunnel where groundwater is seeping in. Inside the tunnel at every 50 metres in the left wall they've constructed alcoves for people caught in the tunnel when the train was coming.  A local company removed and scrapped the tracks after 2001. Today the tunnel is in excellent condition, it is open and can be traversed by bicycle, on foot or by motorized all-terrain vehicles serving as a shortcut from Hunedoara to Govăjdia.
  The second tunnel is at 8 km from Hunedoara at Tulea hamlet from Govăjdia. It is a 42-metre-long curved tunnel serving as a passing through a crest of the mountain. This tunnel is also lined with stone, on the keystone of the tunnel's east portal the date can be seen "1900.12.4". Same as the 747 m tunnel they've removed scrapped the tracks after 2001. The tunnel is in excellent condition; it can be passed only by pedestrians. It cannot be passed through by bicycle or motorized land vehicles because of the dense vegetation.
  The third tunnel is passing through a crest of the mountain located at km 13+520 from Hunedoara, at the confluences of Nădrab and Retişoara rivers. It is a 44-metre-long curved tunnel which has an inside lined with concrete, and the ceiling has traces of soot from the early steam locomotives. The tracks here were removed and scrapped in the early 1990s, after the Retişoara terminus was closed in the 1970s. The west portal of this tunnel and a section of the trackbed is buried under the spoil dump which came from the quarry dolomite and talc from Crăciuneasa hamlet. The tunnel can be approached only on foot.
