Ingalara Creek Railway Bridge, Michelago
The Ingalara Creek railway bridge is a heritage-listed former railway bridge that carried the Bombala railway line across Ingalara Creek at Michelago 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 in 1889. It is also known as the Michelago Rail Bridge over Ingalara Creek and the Ingalara Creek Railway Viaduct. The property is owned by Transport Asset Holding Entity, 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 ...

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] |
Queanbeyan
Queanbeyan ( ) is a city in the south-eastern region of New South Wales, Australia, located adjacent to the Australian Capital Territory in the Southern Tablelands region. Located on the Queanbeyan River, the city is the council seat of the Queanbeyan-Palerang Regional Council. At the , the Queanbeyan part of the Canberra–Queanbeyan built-up area had a population of 37,511. Queanbeyan's economy is based on light construction, manufacturing, service, retail and agriculture. Canberra, Australia's capital, is located to the west, and Queanbeyan is a commuter town. The word ''Queanbeyan'' is the anglicised form of ''Quinbean'', an Aboriginal word meaning ''"clear waters"''. History The first inhabitants of Queanbeyan are Ngambri peoples of the Walgalu Nation, the meeting place of two rivers was known by the local Indigenous population as Quinbean, which is the name of our Historical Journal.

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 ...

Trusses
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 t ...

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 ...

Main North Railway Line, New South Wales
The Main North Line (also known as the Great Northern Railway) is a major railway in New South Wales, Australia. It runs through the Central Coast, Hunter and New England regions. The line was the original main line between Sydney and Brisbane, however this required a change of gauge at Wallangarra. As of 1988, the line closed progressively north of Armidale with services gradually withdrawn till 2004, with the main route between Sydney and Brisbane now the North Coast line. Description of route The line starts as a branch off the Main Suburban line at Strathfield in Sydney. The line heads north as a quadruple track electrified line to Rhodes, crossing the John Whitton Bridge over the Parramatta River as a double track line. At West Ryde the line again expands out to four tracks through to Epping. The line is then largely double track through the northern suburbs of Sydney, crossing the Hawkesbury River Railway Bridge, before passing through the Central Coast. At Fassife ...
