Terras Bridge
Terras Bridge, also known as Terras Pill Bridge, is a road bridge near Morval in Cornwall, England. Built in , the Grade II listed bridge crosses the tidal East Looe River, and is adjacent to the Liskeard and Looe Railway and the remains of the Liskeard and Looe Union Canal. Description Built in , the stone bridge carries an unclassified road over the East Looe River at Terras Pill, between the parishes of Morval and Duloe. As well as the main span across the river channel, the bridge has a second small flood arch. The main bridge arch was navigable, maintaining the river's navigability to Sandplace. Downstream of the bridge, the only crossing of the river is Looe Bridge. At the north side of the bridge, the road continues on a causeway over mudflats and saltings. The East Looe River is tidal as far as Tregarland Bridge – a little over upstream of Terras Bridge – and so flooding of the causeway is not uncommon. At the north end of the causeway crosses the ...

River Fal
The River Fal ( kw, Dowr Fala) flows through Cornwall, England, rising at Pentevale on Goss Moor (between St. Columb and Roche) and reaching the English Channel at Falmouth. On or near the banks of the Fal are the castles of Pendennis and St Mawes as well as Trelissick Garden. The River Fal separates the Roseland peninsula from the rest of Cornwall. Like most of its kind on the south coast of Cornwall and Devon, the Fal estuary is a classic ria, or drowned river valley. The Fal estuary from Tregony to the Truro River was originally called Hafaraell ( kw, Havarel, meaning ''fallow place''). Toponymy The origin and meaning of the name of the river are unknown. The earliest occurrences of the name are in documents from AD 969 and 1049. Falmouth, a town which was named ''Smithwick'' until the 17th century, is named after the River Fal. The word ''Fal'' in Cornish may refer to a prince, or perhaps to a spade or shovel. Robert Williams notes these meanings in his 1865 Cornish ...

Sandplace
Sandplace ( kw, Tewesva) is a small village in the parish of Morval, two miles north of Looe in Cornwall, Great Britain. It is situated on the B3254, the old Liskeard to Looe road which joins the A387 to the south. The village is alongside the East Looe river and has been served by Sandplace railway station, on the Looe Valley Line since 1881. History Sandplace gets its name from a wharf on the river bank where sea-sand was stored, which together with lime (imported from Plymouth and burnt in nearby kilns) was used to improve the acid soils of the area. The fertiliser was transported north out of the village on the Liskeard and Looe Union Canal which was completed in 1828. With the exploitation of copper and tin ores in the Caradon area from 1836 onwards, and the opening of the Liskeard and Caradon Railway in 1844, the canal was not able to cope with the traffic and congestion meant that trade was being lost to competing routes via Calstock and St Germans.

Bridges In Cornwall
A bridge is a structure built to Span (engineering), span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use. Etymology The ''Oxford English Dictionary'' traces ...

Network Rail
Network Rail Limited is the owner (via its subsidiary Network Rail Infrastructure Limited, which was known as Railtrack plc before 2002) and infrastructure manager of most of the railway network in Great Britain. Network Rail is an "arm's length" public body of the Department for Transport with no shareholders, which reinvests its income in the railways. Network Rail's main customers are the private train operating companies (TOCs), responsible for passenger transport, and freight operating companies (FOCs), who provide train services on the infrastructure that the company owns and maintains. Since 1 September 2014, Network Rail has been classified as a "public sector body". To cope with fast-increasing passenger numbers, () Network Rail has been undertaking a £38 billion programme of upgrades to the network, including Crossrail, electrification of lines and upgrading Thameslink. In May 2021, the Government announced its intent to replace Network Rail in 2023 with a n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Train Whistle
A train whistle or air whistle (originally referred to as a steam trumpet) is an audible signaling device on a steam locomotive, used to warn that the train is approaching, and to communicate with rail workers. Modern diesel and electric locomotives primarily use a powerful air horn instead of a whistle as an audible warning device. However, the word ''whistle'' continues to be used by railroaders in referring to such signaling practices as "whistling off" (sounding the horn when a train gets underway). The need for a whistle on a locomotive exists because trains move on fixed rails and thus are uniquely susceptible to collision. This susceptibility is exacerbated by a train's enormous weight and inertia, which make it difficult to quickly stop when encountering an obstacle. Hence a means of warning others of the approach of a train from a distance is necessary. As train whistles are inexpensive compared to other warning devices, the use of loud and distinct whistles became ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Looe Valley Line
The Looe Valley Line is an community railway from Liskeard to Looe in Cornwall, United Kingdom, that follows the valley of the East Looe River for much of its course. It is operated by Great Western Railway. History The Looe Valley Line was opened as the Liskeard and Looe Railway on 27 December 1860 from a station at Moorswater, a little west of Liskeard, to the quayside at Looe, replacing the earlier Liskeard and Looe Union Canal. At Moorswater it connected with the Liskeard and Caradon Railway which conveyed granite from quarries on Bodmin Moor. Passenger services commenced on 11 September 1879, but the Moorswater terminus was inconvenient as it was remote from Liskeard and a long way from the Cornwall Railway station on the south side of the town. On 15 May 1901 the railway opened a curving link line from Coombe Junction, a little south of Moorswater, to the now Great Western Railway station at Liskeard. The section from Coombe Junction to Moorswater was closed to pas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Level Crossings In The United Kingdom
There are around 6,000 level crossings in the United Kingdom, of which about 1,500 are public highway crossings. This number is gradually being reduced as the risk of accidents at level crossings is considered high. The director of the UK Railway Inspectorate commented in 2004 that "the use of level crossings contributes the greatest potential for catastrophic risk on the railways." The creation of new level crossings on the national network is banned (the exception being reopening unavoidable crossings on new/reopening railway lines, and on heritage railways), with bridges and tunnels being the more favoured options. The cost of making significant reductions, other than by simply closing the crossings, is substantial; some commentators argue that the money could be better spent. Some 5,000 crossings are user-worked crossings or footpaths with very low usage. The removal of crossings can improve train performance and lower accident rates, as some crossings have low rail speed l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lock (water Navigation)
A lock is a device used for raising and lowering boats, ships and other watercraft between stretches of water of different levels on river and canal waterways. The distinguishing feature of a lock is a fixed chamber in which the water level can be varied; whereas in a caisson lock, a boat lift, or on a canal inclined plane, it is the chamber itself (usually then called a caisson) that rises and falls. Locks are used to make a river more easily navigable, or to allow a canal to cross land that is not level. Later canals used more and larger locks to allow a more direct route to be taken. Pound lock A ''pound lock'' is most commonly used on canals and rivers today. A pound lock has a chamber with gates at both ends that control the level of water in the pound. In contrast, an earlier design with a single gate was known as a flash lock. Pound locks were first used in China during the Song Dynasty (960–1279 AD), having been pioneered by the Song politician and naval ...

Salt Marsh
A salt marsh or saltmarsh, also known as a coastal salt marsh or a tidal marsh, is a coastal ecosystem in the upper coastal intertidal zone between land and open saltwater or brackish water that is regularly flooded by the tides. It is dominated by dense stands of salt-tolerant plants such as herbs, grasses, or low shrubs. These plants are terrestrial in origin and are essential to the stability of the salt marsh in trapping and binding sediments. Salt marshes play a large role in the aquatic food web and the delivery of nutrients to coastal waters. They also support terrestrial animals and provide coastal protection. Salt marshes have historically been endangered by poorly implemented coastal management practices, with land reclaimed for human uses or polluted by upstream agriculture or other industrial coastal uses. Additionally, sea level rise caused by climate change is endangering other marshes, through erosion and submersion of otherwise tidal marshes. However, r ...

Mudflat
Mudflats or mud flats, also known as tidal flats or, in Ireland, slob or slobs, are coastal wetlands that form in intertidal areas where sediments have been deposited by tides or rivers. A global analysis published in 2019 suggested that tidal flat ecosystems are as extensive globally as mangroves, covering at least of the Earth's surface. / They are found in sheltered areas such as bays, bayous, lagoons, and estuaries; they are also seen in freshwater lakes and salty lakes (or inland seas) alike, wherein many rivers and creeks end. Mudflats may be viewed geologically as exposed layers of bay mud, resulting from deposition of estuarine silts, clays and aquatic animal detritus. Most of the sediment within a mudflat is within the intertidal zone, and thus the flat is submerged and exposed approximately twice daily. A recent global remote sensing analysis estimated that approximately 50% of the global extent of tidal flats occurs within eight countries (Indonesia, China, Austra ...

Causeway
A causeway is a track, road or railway on the upper point of an embankment across "a low, or wet place, or piece of water". It can be constructed of earth, masonry, wood, or concrete. One of the earliest known wooden causeways is the Sweet Track in the Somerset Levels, England, which dates from the Neolithic age. Timber causeways may also be described as both boardwalks and bridges. Etymology When first used, the word ''causeway'' appeared in a form such as "causey way" making clear its derivation from the earlier form "causey". This word seems to have come from the same source by two different routes. It derives ultimately, from the Latin for heel, ''calx'', and most likely comes from the trampling technique to consolidate earthworks. Originally, the construction of a causeway utilised earth that had been trodden upon to compact and harden it as much as possible, one layer at a time, often by enslaved bodies or flocks of sheep. Today, this work is done by machines. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
