Ledbury Tunnel
Ledbury Tunnel is a single-track railway tunnel immediately to the east of Ledbury railway station on the Cotswold Line, in Herefordshire, England. The original route planned for the Worcester and Hereford Railway did not include the tunnel, but its inclusion became necessary in response to pressure for the line to serve the towns of Malvern and Ledbury. Ledbury Tunnel was one of the railway's greatest engineering challenges, being bored through the limestone of Dog Hill; it was opened to traffic during 1861. Possessing a relatively narrow cross-section, the tunnel suffered from a particularly poor atmosphere during the era of steam. Unlike the Colwall tunnel, which was also constructed for the line, Ledbury Tunnel has not been widened, replaced, or substantially reengineered since its original completion in the 1860s. It remains in use through to the present today. History The origins of the Ledbury Tunnel are directly connected to the development of a railway between Worces ...

Ledbury
Ledbury is a market town and civil parish in the county of Herefordshire, England, lying east of Hereford, and west of the Malvern Hills. It has a significant number of timber-framed structures, in particular along Church Lane and High Street. One of the most outstanding is Ledbury Market Hall, built in 1617, located in the town centre. Other notable buildings include the parish church of St. Michael and All Angels, the Painted Room (containing sixteenth-century frescoes), the Old Grammar School, the Barrett-Browning memorial clock tower (designed by Brightwen Binyon and opened in 1896 to house the library until 2015), nearby Eastnor Castle and the St. Katherine's Hospital site. Founded , this is a rare surviving example of a hospital complex, with hall, chapel, a Master's House (fully restored and opened in March 2015 to house the Library), almshouses and a timber-framed barn. History Ledbury is a borough whose origins date to around AD 690. In the Domesday Book it was recor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birmingham
Birmingham ( ) is a city and metropolitan borough in the metropolitan county of West Midlands in England. It is the second-largest city in the United Kingdom with a population of 1.145 million in the city proper, 2.92 million in the West Midlands metropolitan county, and approximately 4.3 million in the wider metropolitan area.

Tunnels In Herefordshire
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossings, are built to allow wildlife to cross human-made barriers safely. Tunne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Railway Tunnels In England
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 faciliti ...

Ostracoderm
Ostracoderms () are the armored jawless fish of the Paleozoic Era. The term does not often appear in classifications today because it is paraphyletic (excluding jawed fishes) (may also be polyphyletic if anaspids are closer to cyclostomes) and thus does not correspond to one evolutionary lineage. However, the term is still used as an informal way of loosely grouping together the armored jawless fishes. An innovation of ostracoderms was the use of gills not for feeding, but exclusively for respiration. Earlier chordates with gill precursors used them for both respiration and feeding. Ostracoderms had separate pharyngeal gill pouches along the side of the head, which were permanently open with no protective operculum. Unlike invertebrates that use ciliated motion to move food, ostracoderms used their muscular pharynx to create a suction that pulled small and slow moving prey into their mouths. Swiss anatomist Louis Agassiz received some fossils of bony armored fish from Scotland ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acanthodian
Acanthodii or acanthodians is an extinct class of gnathostomes (jawed fishes), typically considered a paraphyletic group. They are currently considered to represent a grade of various fish lineages leading up to the extant Chondrichthyes, which includes living sharks, rays, and chimaeras. Acanthodians possess a mosaic of features shared with both osteichthyans (bony fish) and chondrichthyans (cartilaginous fish). In general body shape, they were similar to modern sharks, but their epidermis was covered with tiny rhomboid platelets like the scales of holosteians (gars, bowfins). A lower Silurian species, ''Fanjingshania renovata'', attributed to Climatiiformes is the oldest chondrichthyan with known anatomical features. The popular name "spiny sharks" is because they were superficially shark-shaped, with a streamlined body, paired fins, a strongly upturned tail, and stout, largely immovable bony spines supporting all the fins except the tail—hence, "spiny sharks". However, acan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Devonian
The Devonian ( ) is a geologic period and system of the Paleozoic era, spanning 60.3 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya. It is named after Devon, England, where rocks from this period were first studied. The first significant adaptive radiation of life on dry land occurred during the Devonian. Free-sporing vascular plants began to spread across dry land, forming extensive forests which covered the continents. By the middle of the Devonian, several groups of plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants appeared. The arthropod groups of myriapods, arachnids and hexapods also became well-established early in this period, after starting their expansion to land at least from the Ordovician period. Fish reached substantial diversity during this time, leading the Devonian to often be dubbed the Age of Fishes. The placoderms began dominating ...

Malvern Hills
The Malvern Hills are in the English counties of Worcestershire, Herefordshire and a small area of northern Gloucestershire, dominating the surrounding countryside and the towns and villages of the district of Malvern. The highest summit affords a panorama of the Severn Valley, the hills of Herefordshire and the Welsh mountains, parts of thirteen counties, the Bristol Channel, and the cathedrals of Worcester, Gloucester and Hereford. They are known for their spring water – initially from holy wells, and later the spa town of Great Malvern, which led to the production of the modern bottled drinking water. The Malvern Hills have been designated as a biological and geological Site of Special Scientific Interest, and by Natural England as National Character Area 103 and an Area of Outstanding Natural Beauty. Management of the area is the responsibility of the Malvern Hills Trust. Toponymy The name Malvern is probably derived from the ancient British ''moel-bryn'', meanin ...

Viaduct
A viaduct is a specific type of bridge that consists of a series of arches, piers or columns supporting a long elevated railway or road. Typically a viaduct connects two points of roughly equal elevation, allowing direct overpass across a wide valley, road, river, or other low-lying terrain features and obstacles. The term ''viaduct'' is derived from the Latin ''via'' meaning "road", and ''ducere'' meaning "to lead". It is a 19th-century derivation from an analogy with ancient Roman aqueducts. Like the Roman aqueducts, many early viaducts comprised a series of arches of roughly equal length. Over land The longest in antiquity may have been the Pont Serme which crossed wide marshes in southern France. At its longest point, it measured 2,679 meters with a width of 22 meters. Viaducts are commonly used in many cities that are railroad hubs, such as Chicago, Birmingham, London and Manchester. These viaducts cross the large railroad yards that are needed for freight trains there, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Black Country
The Black Country is an area of the West Midlands county, England covering most of the Metropolitan Boroughs of Dudley, Sandwell and Walsall. Dudley and Tipton are generally considered to be the centre. It became industrialised during its role as one of the birth places of the Industrial Revolution across the English Midlands with coal mines, coking, iron foundries, glass factories, brickworks and steel mills, producing a high level of air pollution. The name dates from the 1840s, and is believed to come from the soot that the heavy industries covered the area in, although the 30-foot-thick coal seam close to the surface is another possible origin. The road between Wolverhampton and Birmingham was described as "one continuous town" in 1785. Extent The Black Country has no single set of defined boundaries. Some traditionalists define it as "the area where the coal seam comes to the surface – so West Bromwich, Coseley, Oldbury, Blackheath, Cradley Heath, Old Hill, B ...
