The tunnel was repaired thereafter and widened to make way for standard gauge trains, which would begin using the tunnel in 1909. The western portal was also replaced due to the earthquake and a brick ceiling was installed for the first three hundred feet of the tunnel to prevent collapse from the sandstone present there. The brick ceiling is ...
The tunnel will have 13 cross-passages, spaced every 500 m (1,640 ft), and 5.5 m (18.0 ft) wide. [12] The eastern portal at Water Orton will have a porous portal, likely in the form of a perforated concrete structure, to mitigate the sound and shockwave produced by the piston effect of moving trains, travelling 230 km/h (145 mph).

The tunnel has a concrete portal barrel with a length of 30.9 feet (9.4 m) located at the north portal. The tunnel was dug through rock of the Franciscan group, consisting mainly of sandstone, conglomerates, and shales. As it stands, the southern part of the tunnel is in a significantly worse state than the northern part.
The Australian state of Victoria has only ever had about 10 tunnels on its railway network, with some others on private narrow gauge tramways. This is due to the relatively easy terrain through which most of the lines were built. The portal of the Big Hill railway tunnel, 390 metres long, originally double-tracked
This shorter tunnel, which passes under the highway, allowed the desired approach to, and siting of, the east portal of the Mount Macdonald Tunnel. [2] Built first was the adjacent Connaught Creek bridge on the Macdonald Track. Using this access, the Manning-Kumagai (MK) joint venture (comprising Manning Construction & Kumagai Gumi) began to ...
Gallitzin Tunnel 0 (1 track 1904-1995), Allegheny Tunnel 2 (1 track 1904-1995), New Portage Tunnel 1 (2 tracks 1898-1971) Track gauge: 4 feet, 8 and one-half inches (56.5 inches) Highest elevation: Gallitzin and Allegheny Tunnels 2,167 feet (at west tunnel portals), New Portage Tunnel 2,198 feet (at AR tower west of west tunnel portal)
The structure gauge S requires buildings to be placed at minimum of 3,100 mm (10 ft 2 + 1 ⁄ 16 in) from the track centreline. Bridges and tunnels must have a clearance of at least 4,900 mm (16 ft 15 ⁄ 16 in) wide and 6,400 mm (20 ft 11 + 15 ⁄ 16 in) high.
The western portals of four railroad tunnels and cuts through Bergen Hill in Jersey City in 1978. From left: the Bergen Tunnels, the Long Dock Tunnel, and the Bergen Arches. Prior to construction, the Morris and Essex Railroad, a predecessor of the DL&W, used the Long Dock Tunnel, owned by the Erie Railroad, to pass under the Hudson Palisades.
