Rhiw-goch Quarry
Rhiw-goch quarry (also known as Brandreath quarry) was a slate quarry that was worked from the 1860s to 1908. It stands on the north side of the Afon Lledr, on the opposite side of the valley from Pont-y-Pant railway station. History The quarry opened in the 1860s and was initially worked into the hillside on an outcrop of the Nod Glas Formation. As the quarry expanded, an open pit was dug down into the slate vein. In 1874, the quarry, which had been in local ownership, was sold to a Mr. Blackwell, who spent a great deal to re-equip the quarry. In 1876, Blackwell contracted Issac Hughes of Rhyl to build a large reservoir in the hills above the quarry. The same year, he appointed David E. Davies as his manager. Davies went on to manage the nearby Ty'n-y-bryn quarry, and died in 1902. A mill was built to the south-east of the pit, likely in 1876 or 1877. The reservoir fed the waterwheel that powered the mill. A water turbine was installed at the mill before 1880, a notably ear ...

Conwy County Borough
Conwy County Borough ( cy, Bwrdeistref Sirol Conwy) is a county borough in Wales. It borders Gwynedd to the west and south, and Denbighshire to the east. Other settlements in the county borough include Abergele, Betws-y-Coed, Colwyn Bay, Conwy, Llandudno, Llandudno Junction, Llanfairfechan, Llanrwst, and Penmaenmawr. Geography The River Conwy, after which the county borough is named, lies wholly within the area: rising in Snowdonia and flowing through Llanrwst and Trefriw en route to the Irish Sea by Conwy. The river here marks the border between the historic counties of Caernarfonshire and Denbighshire. One third of the land area of the county borough lies in the Snowdonia National Park, and the council appoint three of the 18 members of the Snowdonia National Park Authority. Its total area is , making it slightly larger than Hong Kong. The eastern part includes the larger section of Denbigh Moors. The vast majority of the population live on the coast; the only settlement o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slate Industry In Wales
The existence of a slate industry in Wales is attested since the Roman period, when slate was used to roof the fort at Segontium, now Caernarfon. The slate industry grew slowly until the early 18th century, then expanded rapidly until the late 19th century, at which time the most important slate producing areas were in northwest Wales, including the Penrhyn Quarry near Bethesda, the Dinorwic Quarry near Llanberis, the Nantlle Valley quarries, and Blaenau Ffestiniog, where the slate was mined rather than quarried. Penrhyn and Dinorwig were the two largest slate quarries in the world, and the Oakeley mine at Blaenau Ffestiniog was the largest slate mine in the world. Slate is mainly used for roofing, but is also produced as thicker slab for a variety of uses including flooring, worktops and headstones.Lindsay p. 133 Up to the end of the 18th century, slate was extracted on a small scale by groups of quarrymen who paid a royalty to the landlord, carted slate to the ports, and ...

Slate Mines In Conwy County Borough
Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism. It is the finest grained foliated metamorphic rock. Foliation may not correspond to the original sedimentary layering, but instead is in planes perpendicular to the direction of metamorphic compression. The foliation in slate is called "slaty cleavage". It is caused by strong compression causing fine grained clay flakes to regrow in planes perpendicular to the compression. When expertly "cut" by striking parallel to the foliation, with a specialized tool in the quarry, many slates will display a property called fissility, forming smooth flat sheets of stone which have long been used for roofing, floor tiles, and other purposes. Slate is frequently grey in color, especially when seen, en masse, covering roofs. However, slate occurs in a variety of colors even from a single locality; for exam ...

Deganwy
Deganwy (Middle Welsh ''Degannwy'', Brythonic *''Decantouion'') is a town and electoral ward in Conwy County Borough in Wales with a population of 3,936 (2011). It lies in the Creuddyn Peninsula alongside Llandudno (to the north) and Rhos-on-Sea (to its east). Historically part of Caernarfonshire, the peninsula is in a region of north Wales where as many as 1 in 3 of residents are able to speak Welsh, and is home to some of the most expensive streets in Wales. Deganwy is located to the east of the town of Conwy (which is on the opposite side of the River Conwy) and with it forms the Conwy community. The name ''Deganwy'' has been interpreted in modern times as ''Din-Gonwy'', which would mean "Fort on the River Conwy", but the historical spellings make it impossible for this to be the actual origin of the name although mentioned in Domesday Book is "the territory of the Decanae tribe". The original wooden castle was rebuilt in stone after 1210. Deganwy is in the ecclesiastical pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LNWR
The London and North Western Railway (LNWR, L&NWR) was a British railway company between 1846 and 1922. In the late 19th century, the L&NWR was the largest joint stock company in the United Kingdom. In 1923, it became a constituent of the London, Midland and Scottish (LMS) railway, and, in 1948, the London Midland Region of British Railways: the LNWR is effectively an ancestor of today's West Coast Main Line. History The company was formed on 16 July 1846 by the amalgamation of the Grand Junction Railway, London and Birmingham Railway and the Manchester and Birmingham Railway. This move was prompted, in part, by the Great Western Railway's plans for a railway north from Oxford to Birmingham. The company initially had a network of approximately , connecting London with Birmingham, Crewe, Chester, Liverpool and Manchester. The headquarters were at Euston railway station. As traffic increased, it was greatly expanded with the opening in 1849 of the Great Hall, designed by Phil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Level Crossing
A level crossing is an intersection where a railway line crosses a road, Trail, path, or (in rare situations) airport runway, at the same level, as opposed to the railway line crossing over or under using an Overpass#Railway, overpass or tunnel. The term also applies when a light rail line with separate Right-of-way (railroad), right-of-way or reserved track crosses a road in the same fashion. Other names include railway level crossing, railway crossing (chiefly international), grade crossing or railroad crossing (chiefly American), road through railroad, criss-cross, train crossing, and RXR (abbreviated). There are more than 100,000 level crossings in Europe and more than 200,000 in North America. History The history of level crossings depends on the location, but often early level crossings had a Flagman (rail), flagman in a nearby booth who would, on the approach of a train, wave a red flag or lantern to stop all traffic and clear the tracks. Gated crossings bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A470 Road
The A470 (also named the Cardiff to Glan Conwy Trunk Road) is a trunk road in Wales. It is the country's longest road at and links the capital Cardiff on the south coast to Llandudno on the north coast. While previously one had to navigate the narrow roads of Llanidloes and Dolgellau, both these market towns are now bypassed due to extensive road modernisation. The from Cardiff Bay to Merthyr Tydfil are mainly dual carriageway, but most of the route from north of Merthyr to Llandudno is single carriageway. Route National parks The road travels through two of the national parks of Wales: the Brecon Beacons, and Snowdonia National Park starting just south of Dinas Mawddwy. Cardiff Bay – Merthyr Tydfil The southernmost point of the route is in Cardiff Bay, outside the Wales Millennium Centre. It runs up Lloyd George Avenue (this was previously Collingdon Road, and the A470 previously ran along the parallel Bute Street), and continues along St. Mary Street in central Car ...

Tramway (industrial)
Tramways are lightly laid rail transport, railways, sometimes with the wagons or carriages moved without locomotives. Because individual tramway infrastructure is not intended to carry the weight of typical standard-gauge railway equipment, the tramways over which they operate may be built from less substantial materials. Tramways can exist in many forms; sometimes just tracks temporarily placed on the ground to transport materials around a factory, mine or quarry. Many, if not most, use narrow-gauge railway technology. The trains can be manually pushed by hand, pulled by animals (especially horses and mules), cable hauled by a stationary engine, or use small, light locomotives. The term is not in use in North America but in common use in the United Kingdom, and elsewhere, where British Railway terminology and practices had large influences on management practices, terminology, and railway cultures such as Australia, New Zealand, and those parts of Asia that consulted with Bri ...

Syncline
In structural geology, a syncline is a fold with younger layers closer to the center of the structure, whereas an anticline is the inverse of a syncline. A synclinorium (plural synclinoriums or synclinoria) is a large syncline with superimposed smaller folds. Synclines are typically a downward fold (synform), termed a synformal syncline (i.e. a trough), but synclines that point upwards can be found when strata have been overturned and folded (an antiformal syncline). Characteristics On a geologic map, synclines are recognized as a sequence of rock layers, with the youngest at the fold's center or ''hinge'' and with a reverse sequence of the same rock layers on the opposite side of the hinge. If the fold pattern is circular or elongate, the structure is a basin. Folds typically form during crustal deformation as the result of compression that accompanies orogenic mountain building.

Lledr Valley
The Lledr Valley () is a valley in Snowdonia in north Wales. It runs from the top of the Crimea Pass, north of Blaenau Ffestiniog down to Betws-y-Coed. The A470 road follows the line of the valley, as does the railway line from Blaenau Ffestiniog to Llandudno, and within the valley there are stations at Roman Bridge, Dolwyddelan, and Pont-y-Pant. Dolwyddelan is the main settlement in the valley. The river Lledr, which gives its name to the valley, joins the River Conwy to the south of Betws-y-Coed. Industry During the Victorian period the valley was renowned for its slate quarries, which were concentrated around Dolwyddelan. These quarries worked the Nod Glas Formation, which extended across Mid and North Wales. It was primarily a bed of soft, black shale, but in the area of the Dolwyddelan syncline it was partially metamorphisised into slate. The principle quarries in the valley were: * Prince Llewellyn quarry and Chwarel Fedw * Chwarel Ddu * Ty'n-y-bryn quarry and ...
