Map with all coordinates: The Overvaal Tunnel is a 3.9 km long rail tunnel on the Richards Bay Coal Line in South Africa . The railway tunnel built in 1974 is single-track and represents a capacity bottleneck for the removal of coal from the Mpumalanga province, which is why the construction of a second tunnel about 20 m south of the existing tunnel is planned.
The existing tunnel was created with a horseshoe-shaped cross-section using blasting . The track is laid in the tunnel on a concrete base that had to be rehabilitated with epoxy injections in 2007 due to subsidence and water damage.
