Having been part of a former colliery's wooden waggonway,
the Tanfield Railway can trace its history back
to 1725, and as such claims to be the oldest working railway in the
world. In the 1850s steam traction was introduced to the line -
these continued until the railway's closure in 1970.
Following the dedicated efforts of the preservation group, the line opened as a heritage railway in 1973, and today it operates a number of steam-hauled services, with vintage carriages from the 19th century.
