Lithgow Underbridge
The Lithgow Underbridge is a heritage-listed railway underbridge that carries the Main West Line over James Street, in Lithgow, in the City of Lithgow local government area of New South Wales, Australia. The bridge is located approximately from Central railway station. The bridge was designed by John Whitton as the Engineer-in-Chief for Railways and was built in 1869 by contractor, P. Higgins. It is also known as Lithgow (James St) Underbridge. 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 30 August 2013. History The Main West Railway Line runs from Granville to Bourke and was completed in 1885. By 1900 certain sections of John Whitton's single track railway network were operating at or near saturation, these included the famous Zig Zag near Lithgow, the Main West from Emu Plains right through to Bathurst, the Main South from Picton as far as Harde ...

Emu Plains, New South Wales
Emu Plains is a suburb of Sydney in the state of New South Wales, Australia. It is 58 kilometres west of the Sydney central business district, in the local government area of the City of Penrith and is part of the Greater Western Sydney region. Emu Plains is on the western side of the Nepean River, located at the foot of the Blue Mountains. History Aboriginal culture Prior to European settlement, what is now Emu Plains was on the border of the Western Sydney-based Darug people and the Southern Highlands-based Gandangara people, whose land extended into the Blue Mountains. The local Darug people were known as the Mulgoa who lived a hunter-gatherer lifestyle governed by traditional laws, which had their origins in the Dreamtime. They lived in huts made of bark called 'gunyahs', hunted kangaroos and emus for meat, and gathered yams, berries and other native plants. European settlement The first British explorers to visit the area surveyed Emu Plains in August 1790 led by Wat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spandrel
A spandrel is a roughly triangular space, usually found in pairs, between the top of an arch and a rectangular frame; between the tops of two adjacent arches or one of the four spaces between a circle within a square. They are frequently filled with decorative elements. Meaning There are four or five accepted and cognate meanings of the term ''spandrel'' in architectural and art history, mostly relating to the space between a curved figure and a rectangular boundary – such as the space between the curve of an arch and a rectilinear bounding moulding, or the wallspace bounded by adjacent arches in an arcade and the stringcourse or moulding above them, or the space between the central medallion of a carpet and its rectangular corners, or the space between the circular face of a clock and the corners of the square revealed by its hood. Also included is the space under a flight of stairs, if it is not occupied by another flight of stairs. In a building with more than one floor ...

Impost (architecture)
In architecture, an impost or impost block is a projecting block resting on top of a column or embedded in a wall, serving as the base for the springer or lowest voussoir of an arch. Ornamental training The imposts are left smooth or profiled, and "then express a certain separation between abutment and arch." The Byzantine fighters are high blocks, which are sometimes referred to as pulvino. The Romanesque designed the impost ornamentally or figuratively, similar to the capitals. In the Gothic period, the fighter almost completely disappeared from the calyx bud capital. The architecture of the Renaissance returns to the formation of the imposts of the ancient column orders. See also * Capital (architecture) * Abacus (architecture) * Pulvino A pulvino (or impost block) is an architectural structural element ( dosseret) having the shape of an inverted pyramid cushion, which is placed between the column capital and the arch base.

Parapet
A parapet is a barrier that is an extension of the wall at the edge of a roof, terrace, balcony, walkway or other structure. The word comes ultimately from the Italian ''parapetto'' (''parare'' 'to cover/defend' and ''petto'' 'chest/breast'). Where extending above a roof, a parapet may simply be the portion of an exterior wall that continues above the edge line of the roof surface, or may be a continuation of a vertical feature beneath the roof such as a fire wall or party wall. Parapets were originally used to defend buildings from military attack, but today they are primarily used as guard rails, to conceal rooftop equipment, reduce wind loads on the roof, and to prevent the spread of fires. In the Bible the Hebrews are obligated to build a parapet on the roof of their houses to prevent people falling (Deuteronomy 22:8). Parapet types Parapets may be plain, embattled, perforated or panelled, which are not mutually exclusive terms. *Plain parapets are upward extensions of ...

Pier (architecture)
A pier, in architecture, is an upright support for a structure or superstructure such as an arch or bridge. Sections of structural walls between openings (bays) can function as piers. External or free-standing walls may have piers at the ends or on corners. Description The simplest cross section of the pier is square, or rectangular, but other shapes are also common. In medieval architecture, massive circular supports called drum piers, cruciform (cross-shaped) piers, and compound piers are common architectural elements. Columns are a similar upright support, but stand on a round base. In buildings with a sequence of bays between piers, each opening (window or door) between two piers is considered a single bay. Bridge piers Single-span bridges have abutments at each end that support the weight of the bridge and serve as retaining walls to resist lateral movement of the earthen fill of the bridge approach. Multi-span bridges require piers to support the ends of spans betwe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Wallerawang
Wallerawang is a small township in the Central Tablelands of New South Wales, Australia. It is located approximately northwest of Lithgow adjacent to the Great Western Highway. It is also located on the Main Western railway line at the junction of the Gwabegar line. History The original inhabitants of the area west of the Blue Mountains were the Wiradjuri Aboriginal Australians. It is believed they knew the area as ''Waller-owang''. It is understood to mean ''place near wood and water'', or ''plenty of water''. James Blackman was probably the first European to visit the area when he marked out the route of the new road from Bathurst to the area now known as Wallerawang. In 1824, 11 years after the first exploration led by Blaxland over the Blue Mountains, a James Walker was granted a large portion of land in the area now known as Wallerawang. In 1836 the property was to become known as Barton Park. Two of Walker's convict servants took up land leases in the area in t ...

Bowenfels, New South Wales
Bowenfels is a small town on the western outskirts of Lithgow, New South Wales, Australia. Today there are effectively two Bowenfels. Near Lithgow, on the Great Western Highway, is Bowenfels (with the homestead of the valley's first settler, Andrew Brown). About a kilometre south is . Although both are now essentially suburbs of Lithgow, Bowenfels was, in fact, the first settlement in the valley, pre-dating the existence of Lithgow by nearly 40 years. History Mount Blaxland, a short distance from South Bowenfels, was the furthest point reached by Blaxland, Lawson, and Wentworth on their historic expedition across the Blue Mountains in 1813. Later in that year George Evans followed in the footsteps of the explorers to Mount Blaxland and then headed west to discover the O'Connell plains and the Bathurst plains.
