Daylighting (tunnels)
Daylighting a tunnel is to remove its "roof" of overlying rock and soil, exposing the railway or roadway to daylight and converting it to a railway or roadway Cut (earthmoving), cut. Tunnels are often daylighted to improve vertical or horizontal clearances—for example, to accommodate Double-stack rail transport, double-stack container trains or electrifying rail lines, where increasing the size of the tunnel bore is impractical. List of daylighted tunnels * Australia ** The Moocomonga Tunnel carried the Central Western railway line, Queensland, Central Western railway line through the Gogango Range in Queensland, Australia (). It opened in 1876. The tunnel was daylighted in 1983 due to rock falls which blocked the tunnel from time to time. ** The Coromandel and Pinera Tunnel, Pinera Tunnels on the Belair line in Adelaide, South Australia, both built as a single track tunnel with the line in 1883, were daylighted in the 1920s when the line to Belair, South Australia, Belair wa ...

Tunnel
A tunnel is an underground or undersea passageway. It is dug through surrounding soil, earth or rock, or laid under water, and is usually completely enclosed except for the two portals common at each end, though there may be access and ventilation openings at various points along the length. A pipeline differs significantly from a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment.Salazar, Waneta.

At long, the Manawatū Gorge divides the Ruahine and Tararua Ranges, linking the Manawatū and Tararua Districts. It lies to the northeast of Palmerston North. Its western end is near the small town of Ashhurst and its eastern end is close to the town of Woodville. As one of the few links between the eastern and western North Island, the gorge is an important transport link, with the Palmerston North–Gisborne Line passing through the gorge, as well as State Highway 3 until 2017. Recreationally, the gorge is part of the Manawatū Gorge Scenic Reserve, with various walking tracks through the surrounding native bush. Whātonga, a Māori explorer from the Kurahaupō canoe, is said to have found the gorge in about the 12th century.
