Bredbo Rail Bridge
The Bredbo River railway bridge is a heritage-listed former railway bridge carrying the Bombala railway line over the Bredbo River at Bredbo in the Snowy Monaro Regional Council local government area of New South Wales, Australia. It was designed by John Whitton in his capacity as Engineer-in-Chief for Railways and built from 1881 to 1889. It is also known as the Bredbo Rail Bridge and the Bredbo River Railway Viaduct. The property is owned by RailCorp, an agency of the Government of New South Wales. It was added to the New South Wales State Heritage Register on 2 April 1999. On 1 December 2020, changes were made to exemptions relating to the bridge's heritage status. History The railway was extended from Queanbeyan to Cooma in 1887-89. At that time, the Engineer-in-Chief for Railways, John Whitton, was under government pressure to reduce construction costs. One common method was to build timber bridges, mostly ballast top timber beam bridges. However, for two major waterways ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bombala Railway Line
The Bombala railway line is a branch railway line in the south of New South Wales, Australia. The northern part of it forms part of the main line from Sydney to Canberra, but the southern part is closed. It branches off the Main South line at Joppa Junction, south of Goulburn. The line is used by NSW TrainLink Xplorer services running between Sydney Central and Canberra station. History The line was opened in stages to Tarago (January 1884), Bungendore (March 1885), Queanbeyan (September 1887), Michelago (December 1887), Cooma (May 1889), Nimmitabel (April 1912) and Bombala (November 1921). Queanbeyan The section of the line, between Bungendore and Queanbeyan, was the most challenging to construct, with three tunnels, a major sideling embankment along the Molonglo River gorge (also known as 'Pine Valley'), and two major bridges, across the Molonglo and Queanbeyan Rivers. The construction contract for the line from Bungendore to Michelago was awarded to Johnstone and Co. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Railway Bridges In New South Wales
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Monaro (New South Wales)
Monaro ( ), once frequently spelled "Manaro", or in early years of settlement "Maneroo" is a region in the south of New South Wales, Australia. A small area of Victoria near Snowy River National Park is geographically part of the Monaro. While the Australian Capital Territory is not considered part of the region, some towns in the Monaro have close links with Canberra. The Snowy Monaro Regional Council was established in 2016 which comprises the former Bombala, Cooma-Monaro and Snowy River Local Government Areas. The area was traditionally inhabited by Ngarigo, Walgalu, Bidawal and Southern Ngunnawal people. It boasts of snowfields, expansive timber forests and the Snowy River. Holden's 'Monaro' Coupe (and later sedan) models ( 1967-1977, 2001-2006, 1973-1974 (Sedan)) were named after the area. Geography The Monaro region is a plateau area lying about 1000 metres above sea level, extending from the valley of the Murrumbidgee River in the north to the Errinundra Plateau in t ...

Monaro Highway
Monaro Highway is a highway in Victoria, New South Wales, and the Australian Capital Territory, in Australia, linking in Victoria to Canberra in the Australian Capital Territory (ACT) via the Monaro region. From its southern terminus, it follows the nearby Cann River upstream towards the New South Wales border through heavily forested terrain. Within New South Wales (NSW), it makes its way through further forest before reaching the pastures typical of the Monaro. There are multiple towns and villages along the highway, including , , and . The terrain within the Monaro is largely hilly, and there are numerous crossings. The road also parallels the former Bombala railway line in several locations. Within the ACT, the road becomes a high volume roadway and serves the southern suburbs of Canberra. The highway has more recently had a grade-separated dual carriageway extension constructed within Canberra, as part of the Eastern Parkway construction project. It is designated part of r ...

Cornwall Railway Viaducts
The Cornwall Railway company constructed a railway line between Plymouth and Truro in the United Kingdom, opening in 1859, and extended it to Falmouth in 1863. The topography of Cornwall is such that the route, which is generally east–west, cuts across numerous deep river valleys that generally run north–south. At the time of construction of the line, money was in short supply due to the collapse in confidence following the railway mania, and the company sought ways of reducing expenditure. On the advice of the Victorian railway engineer Isambard Kingdom Brunel, they constructed the river crossings in the form of wooden viaducts, 42 in total, consisting of timber deck spans supported by fans of timber bracing built on masonry piers. This unusual method of construction substantially reduced the first cost of construction compared to an all-masonry structure, but at the cost of more expensive maintenance. Replacement of the timber viaducts by all-masonry structures began in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isambard Kingdom Brunel
Isambard Kingdom Brunel (; 9 April 1806 – 15 September 1859) was a British civil engineer who is considered "one of the most ingenious and prolific figures in engineering history," "one of the 19th-century engineering giants," and "one of the greatest figures of the Industrial Revolution, hochanged the face of the English landscape with his groundbreaking designs and ingenious constructions." Brunel built dockyards, the Great Western Railway (GWR), a series of steamships including the first propeller-driven transatlantic steamship, and numerous important bridges and tunnels. His designs revolutionised public transport and modern engineering. Though Brunel's projects were not always successful, they often contained innovative solutions to long-standing engineering problems. During his career, Brunel achieved many engineering firsts, including assisting in the building of the first tunnel under a navigable river (the River Thames) and the development of the , the first ...

Truss
A truss is an assembly of ''members'' such as beams, connected by ''nodes'', that creates a rigid structure. In engineering, a truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object". A "two-force member" is a structural component where force is applied to only two points. Although this rigorous definition allows the members to have any shape connected in any stable configuration, trusses typically comprise five or more triangular units constructed with straight members whose ends are connected at joints referred to as ''nodes''. In this typical context, external forces and reactions to those forces are considered to act only at the nodes and result in forces in the members that are either tensile or compressive. For straight members, moments (torques) are explicitly excluded because, and only because, all the joints in a truss are treated as revolutes, as is necessary for ...

Span (architecture)
Span is the distance between two intermediate supports for a structure, e.g. a beam (structure), beam or a bridge. A span can be closed by a solid beam or by a rope. The first kind is used for bridges, the second one for power lines, overhead telecommunication lines, some type of Antenna (radio), antennas or for aerial tramways. The span is a significant factor in finding the strength and size of a beam as it determines the maximum bending moment and Deflection (engineering), deflection. The maximum bending moment M_ and deflection \delta_in the pictured beam is found using: :M_ = \frac :\delta_ = \frac = \frac where :q = Uniformly distributed load :L = Length of the beam between two supports (span) :E = Modulus of elasticity :I = Area moment of inertia Note that the maximum bending moment and deflection occur midway between the two supports. From this it follows that if the span is doubled, the maximum moment (and with it the tensile stress, stress) will quadruple, and ...
