Barmouth
Barmouth ( cy, Abermaw (formal); ''Y Bermo'' (colloquial)) is a seaside town and community (Wales), community in the county of Gwynedd, northwestern Wales, lying on the estuary of the Afon Mawddach and Cardigan Bay. Located in the Historic counties of Wales, historic county of Merionethshire, the Welsh form of the name is derived from ''aber'' (estuary) and the river's name, "Mawddach". The English form of the name is a corruption of the earlier Welsh form ''Abermawdd''. The community includes the villages of Llanaber, Cutiau, and Bro Ardudwy, Caerdeon. History The town grew around the shipbuilding industry, and more recently as a seaside resort. Notable buildings include the medieval tower house, the 19th century Roundhouse (dwelling), roundhouse prison and St John's Church, Barmouth, St John's Church. William Wordsworth, a visitor to Barmouth in the 19th century, described it thus: "With a fine sea view in front, the mountains behind, the glorious estuary running inla ...

Afon Mawddach
The Afon Mawddach ( en, River Mawddach, italic=yes) is a river in Gwynedd, Wales, which has its source in a wide area north of Dduallt in Snowdonia. It is 28 miles (45 km) in length, and is much branched; many of the significant tributaries are of a similar size to the main river. The catchment area is bounded to the east by the Aran Fawddwy massif and to the west and north by the Harlech dome which forms a watershed just south of Llyn Trawsfynydd. The Mawddach has been the site of significant industrialisation and land management. Gold mining and subsequently gold panning have had major impacts but forestry, the preparation of animal skins, the storage of old munitions and the use of hill-sides as artillery ranges have all added to the legacy of pollution. The river is also very ''flashy'' - prone to very rapid rise and fall in level depending on rainfall. Rainfall can also be very heavy and it falls on very base-poor soils leading to episodes of strongly depressed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pont Briwet
Pont Briwet refers to the road and railway bridges that cross the River Dwyryd, near Penrhyndeudraeth, Gwynedd in North Wales. The first bridge was a Victorian road and railway viaduct that was constructed entirely from timber by the Cambrian Railways company. Although it was recognised as being a Grade II listed structure, a result of it being an increasingly rare example of a surviving 19th-century wooden road and railway viaduct, the condition of the bridge had deteriorated over time and by the 21st century was posing regular and considerable inconvenience to both road and rail traffic. Due to the operational impact of the old bridge, it was decided to build a replacement structure alongside as a joint project between the Welsh government and national rail infrastructure company Network Rail to upgrade the route. Despite plans to retain the old bridge for pedestrian traffic, it was determined that it had been further weakened and rendered structurally unsafe by the piling pe ...

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 ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tidal Surges
A storm surge, storm flood, tidal surge, or storm tide is a coastal flood or tsunami-like phenomenon of rising water commonly associated with low-pressure weather systems, such as cyclones. It is measured as the rise in water level above the normal tidal level, and does not include waves. The main meteorological factor contributing to a storm surge is high-speed wind pushing water towards the coast over a long fetch. Other factors affecting storm surge severity include the shallowness and orientation of the water body in the storm path, the timing of tides, and the atmospheric pressure drop due to the storm. There is a suggestion that climate change may be increasing the hazard of storm surges. Some theorize that as extreme weather becomes more intense and sea level rises due to climate change, storm surge is expected to cause more risk to coastal populations. Communities and governments can adapt by building hard infrastructure, like surge barriers, soft infrastructure, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Multiple Unit
A diesel multiple unit or DMU is a multiple-unit train powered by on-board diesel engines. A DMU requires no separate locomotive, as the engines are incorporated into one or more of the carriages. Diesel-powered single-unit railcars are also generally classed as DMUs. Diesel-powered units may be further classified by their transmission type: diesel–mechanical DMMU, diesel–hydraulic DHMU, or diesel–electric DEMU. Design The diesel engine may be located above the frame in an engine bay or under the floor. Driving controls can be at both ends, on one end, or in a separate car. Types by transmission DMUs are usually classified by the method of transmitting motive power to their wheels. Diesel–mechanical In a diesel–mechanical multiple unit (DMMU), the rotating energy of the engine is transmitted via a gearbox and driveshaft directly to the wheels of the train, like a car. The transmissions can be shifted manually by the driver, as in the great majority of first-gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Rail Class 158
The British Rail Class 158 '' Express Sprinter'' is a diesel multiple unit (DMU) passenger train. It is a member of the Sprinter series of regional trains, produced as a replacement for British Rail's first generation of DMUs; of the other members, the Class 159 is almost identical to the Class 158, having been converted from Class 158 to Class 159 in two batches to operate express services from London Waterloo to the West of England. The Class 158 was constructed between 1989 and 1992 by British Rail Engineering Limited (BREL) at its Derby Litchurch Lane Works. The majority were built as two-car sets, some three-car sets were also produced. During September 1990, the first Express Sprinters were operated by ScotRail; the type was promptly introduced to secondary routes across the Midlands, Northern England, Wales and the South West. The Class 158 enabled the replacement of large numbers of elderly DMUs but also several locomotive-hauled trains as well; this was partially a ...

Llangollen Railway
The Llangollen Railway () is a volunteer-run heritage railway in Denbighshire, North Wales, which operates between Llangollen and Corwen. The standard gauge line, which is long, runs on part of the former Ruabon – Barmouth GWR route that closed in 1965. It operates daily services in the summer as well as weekends throughout the winter months, using a variety of mainly ex-GWR steam locomotives as well as several diesel engines and diesel multiple units. A extension of the railway has been built to complete the line to Corwen. In March 2021 the railway company announced that, having made a loss in three consecutive years, they had invited their bank to appoint receivers. History Commercial Service: 1865–1962 Llangollen was already a popular place for tourists by the 1840s. Travel up to this time had been by horse-drawn carriage, but by the 1840s the Shrewsbury to Chester line had been completed, which allowed passengers to alight at (later known as Whitehurst Halt), an ...

RETB
Radio Electronic Token Block is a system of railway signalling used in the United Kingdom. It is a development of the physical token system for controlling traffic on single lines. The system is slightly similar to North American Direct Traffic Control, which unlike RETB does not have a cab display unit. Operation On arrival at a "token exchange point", the driver reports their position to the signaller by radio and requests the "token" for the next section of line ahead. If the signaller is in a position to do so, they will issue the electronic token applicable to the section ahead. Simultaneously, the driver must operate a button on an apparatus in the cab to receive the token. The token is then transmitted to the train by radio. The Solid State Interlocking controlling the system prevents the issue of any token permitting conflicting movements. In the same way as with the traditional system, when a physical token with the name of the section engraved on it would be carried ...

Railway Signalling
Railway signalling (), also called railroad signaling (), is a system used to control the movement of railway traffic. Trains move on fixed rails, making them uniquely susceptible to collision. This susceptibility is exacerbated by the enormous weight and inertia of a train, which makes it difficult to quickly stop when encountering an obstacle. In the UK, the Regulation of Railways Act 1889 introduced a series of requirements on matters such as the implementation of interlocked block signalling and other safety measures as a direct result of the Armagh rail disaster in that year. Most forms of train control involve movement authority being passed from those responsible for each section of a rail network (e.g. a signalman or stationmaster) to the train crew. The set of rules and the physical equipment used to accomplish this determine what is known as the ''method of working'' (UK), ''method of operation'' (US) or ''safeworking'' (Aus.). Not all these methods require the use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Signal Box
In signal processing, a signal is a function that conveys information about a phenomenon. Any quantity that can vary over space or time can be used as a signal to share messages between observers. The ''IEEE Transactions on Signal Processing'' includes audio, video, speech, image, sonar, and radar as examples of signal. A signal may also be defined as observable change in a quantity over space or time (a time series), even if it does not carry information. In nature, signals can be actions done by an organism to alert other organisms, ranging from the release of plant chemicals to warn nearby plants of a predator, to sounds or motions made by animals to alert other animals of food. Signaling occurs in all organisms even at cellular levels, with cell signaling. Signaling theory, in evolutionary biology, proposes that a substantial driver for evolution is the ability of animals to communicate with each other by developing ways of signaling. In human engineering, signals are typi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
