Emborough Quarries
Emborough Quarries () is a 1 hectare (2.5 acre) geological Site of Special Scientific Interest at Emborough in the Mendip Hills, Somerset, notified in 1971. The disused quarry has yielded a wide variety of remains of vertebrate fossils, amongst which the early reptiles are particularly well represented. Of special note is Kuehneosaurus latus which is one of the earliest-known flying vertebrates. During the Triassic period of geological time, some 230 million years ago, the limestones now exposed on Mendip formed upland areas upon which a number of large rivers rose. Solution cavities were soon created in the land surface and material from the surrounding area was swept into the newly formed cave systems. Remains of the creatures living in the upland areas during this time were swept into these deposits and have now been exhumed by recent quarrying activities. Fresh material is brought to the surface with every rock fall and Emborough Quarries are a nationally important source ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hectare
The hectare (; SI symbol: ha) is a non-SI metric unit of area equal to a square with 100-metre sides (1 hm2), or 10,000 m2, and is primarily used in the measurement of land. There are 100 hectares in one square kilometre. An acre is about and one hectare contains about . In 1795, when the metric system was introduced, the ''are'' was defined as 100 square metres, or one square decametre, and the hectare ("hecto-" + "are") was thus 100 ''ares'' or km2 (10,000 square metres). When the metric system was further rationalised in 1960, resulting in the International System of Units (), the ''are'' was not included as a recognised unit. The hectare, however, remains as a non-SI unit accepted for use with the SI and whose use is "expected to continue indefinitely". Though the dekare/decare daa (1,000 m2) and are (100 m2) are not officially "accepted for use", they are still used in some contexts. Description The hectare (), although not a unit of SI, i ...

Track Gauge
In rail transport, track gauge (in American English, alternatively track gage) is the distance between the two rails of a railway track. All vehicles on a rail network must have wheelsets that are compatible with the track gauge. Since many different track gauges exist worldwide, gauge differences often present a barrier to wider operation on railway networks. The term derives from the metal bar, or gauge, that is used to ensure the distance between the rails is correct. Railways also deploy two other gauges to ensure compliance with a required standard. A '' loading gauge'' is a two-dimensional profile that encompasses a cross-section of the track, a rail vehicle and a maximum-sized load: all rail vehicles and their loads must be contained in the corresponding envelope. A ''structure gauge'' specifies the outline into which structures (bridges, platforms, lineside equipment etc.) must not encroach. Uses of the term The most common use of the term "track gauge" refers to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Quarries In The Mendip Hills
A quarry is a type of open-pit mine in which dimension stone, rock, construction aggregate, riprap, sand, gravel, or slate is excavated from the ground. The operation of quarries is regulated in some jurisdictions to reduce their environmental impact. The word ''quarry'' can also include the underground quarrying for stone, such as Bath stone. Types of rock Types of rock extracted from quarries include: *Chalk * China clay * Cinder *Clay *Coal * Construction aggregate (sand and gravel) * Coquina * Diabase *Gabbro *Granite * Gritstone *Gypsum *Limestone * Marble * Ores *Phosphate rock *Quartz *Sandstone * Slate *Travertine Stone quarry Stone quarry is an outdated term for mining construction rocks (limestone, marble, granite, sandstone, etc.). There are open types (called quarries, or open-pit mines) and closed types ( mines and caves). For thousands of years, only hand tools had been used in quarries. In the 18th century, the use of drilling and blasting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quarries Of The Mendip Hills
The Mendip Hills, (Mendips) in northern Somerset, are the most southerly Carboniferous Limestone uplands in Britain. The Mendips comprise three major anticlinal structures, each with a core of older Devonian sandstone and Silurian volcanic rocks. The latter, after crushing, is use in road construction and concrete. Devonian Sandstone is visible around Black Down and Downhead. Carboniferous Limestone, dominates the hills and surround the older rock formations. An outcrop of basalt is also quarried at Moon's Hill. For centuries the stone of the Mendips, and the Cotswolds to the north, have been used to build the cities of Bristol and Bath, and many Somerset towns. As stone transportation is expensive, the Mendips, and Leicestershire, are important as the nearest sources of hard stone for London and the South East. The Mendip quarries produce twelve million tonnes of stone a year, employ two thousand people, and have an annual turnover of £150m. Five million tonnes of s ...

Gloddfa Ganol
Gloddfa Ganol (also known as the Gloddfa Ganol Mountain Center) was a museum dedicated to the Welsh slate industry and narrow-gauge railways, situated in the Oakeley slate quarry in Blaenau Ffestiniog. It opened in 1974 and closed in 1998 following an auction of its exhibits. Gloddfa Ganol Mountain Center The Oakeley slate quarry was the largest underground slate mine in the world, but it suffered from a sharp decline in worldwide demand for slate after the Second World War. As quarrying declined in the 1970s, the owners sought to diversify to serve the growing tourist trade in Wales. In 1974 the abandoned Middle Quarry was re-opened, producing architectural slab, and as an attraction to the public - the Gloddfa Ganol Mountain Center. The centre offered guided tours of several miles of underground tunnels and chambers and was based in the old Middle Mill, which had been rebuilt for the purpose. Rich Morris collection Railway enthusiast Rich Morris began collecting narrow ga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hunslet Engine Company
The Hunslet Engine Company is a locomotive-building company, founded in 1864 in Hunslet, England. It manufactured steam locomotives for over 100 years and currently manufactures diesel shunting locomotives. The company is part of Ed Murray & Sons. History The early years 1864–1901 The company was founded in 1864 at Jack Lane in Hunslet by John Towlerton Leather, a civil engineering contractor, who appointed James Campbell (son of Alexander Campbell, a Leeds engineer) as his works manager. The first engine was completed in 1865. It was ''Linden'', a standard gauge delivered to Brassey and Ballard, a railway civil engineering contractor as were several of the firm's early customers. Other customers included collieries. This basic standard gauge shunting and short haul "industrial" engine was to be the main-stay of Hunslet production for many years.

Yorkshire Engine Company
The Yorkshire Engine Company (YEC) was a small independent locomotive manufacturer in Sheffield, England. The company was formed in 1865 and produced locomotives and carried out general engineering work until 1965. It mainly built shunting engines for the British market, but also built main line engines for overseas customers. Steam locomotives were built from 1865 to 1956 and diesel locomotives from 1950 to 1965. The early years The idea of a locomotive builder based near Sheffield was first suggested in 1864 by W. G. Eden, who later became the fourth Baron Auckland. At the time, Eden was Chairman of the South Yorkshire Railway, and a director of the Manchester, Sheffield and Lincolnshire Railway (MSLR), posts which he had taken up after retiring as a diplomat. He invited Archibald Sturrock, who was employed by the Great Northern Railway as its locomotive engineer, to be the Chairman of the new company.

Industrial Railway
An industrial railway is a type of railway (usually private) that is not available for public transportation and is used exclusively to serve a particular industrial, logistics, or military site. In regions of the world influenced by British railway culture and management practices, they are often referred to as tramways (which are distinct from trams or streetcars, a passenger technology). Industrial railways may connect the site to public freight networks through sidings, or may be isolated (sometimes very far away from public rail or surface roads) or located entirely within a served property. Overview Industrial railways were once very common, but with the rise of road transport, their numbers have greatly diminished. An example of an industrial railway would transport bulk goods, for example clay from a quarry or coal from a mine, to an interchange point, called an exchange siding, with a main line railway, onwards from where it would be transported to its final desti ...
