Railway Coupling
A coupling or coupler is a mechanism, typically located at each end of a rolling stock, rail vehicle, that connects them together to form a train. The equipment that connects the couplers to the vehicles is the draft gear or draw gear, which must absorb the stresses of the coupling and the acceleration of the train. Throughout the history of rail vehicles, a variety of coupler designs and types have been developed worldwide. Key design considerations include strength, reliability, easy and efficient handling, and operator safety. Automatic couplers engage automatically when the cars are pushed together. Modern versions not only provide a mechanical connection, but can also couple brake lines and data lines. Different countries use different types of couplers. While North American railroads and China use Janney couplers, railroads in the former Soviet Union use SA3 couplers and the European countries use Scharfenberg coupler, Scharfenberg and Buffers and chain coupler, screw ...

Great Britain
Great Britain is an island in the North Atlantic Ocean off the north-west coast of continental Europe, consisting of the countries England, Scotland, and Wales. With an area of , it is the largest of the British Isles, the List of European islands by area, largest European island, and the List of islands by area, ninth-largest island in the world. It is dominated by a maritime climate with narrow temperature differences between seasons. The island of Ireland, with an area 40 per cent that of Great Britain, is to the west – these islands, along with over List of islands of the British Isles, 1,000 smaller surrounding islands and named substantial rocks, comprise the British Isles archipelago. Connected to mainland Europe until 9,000 years ago by a land bridge now known as Doggerland, Great Britain has been inhabited by modern humans for around 30,000 years. In 2011, it had a population of about , making it the world's List of islands by population, third-most-populous islan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Narrow Gauge Railway
A narrow-gauge railway (narrow-gauge railroad in the US) is a railway with a track gauge (distance between the rails) narrower than . Most narrow-gauge railways are between and . Since narrow-gauge railways are usually built with Minimum railway curve radius, tighter curves, smaller structure gauges, and lighter Rail profile, rails; they can be less costly to build, equip, and operate than standard- or broad-gauge railways (particularly in mountainous or difficult terrain). Lower-cost narrow-gauge railways are often used in mountainous terrain, where engineering savings can be substantial. Lower-cost narrow-gauge railways are often built to serve industries as well as sparsely populated communities where the traffic potential would not justify the cost of a standard- or broad-gauge line. Narrow-gauge railways have specialised use in mines and other environments where a small structure gauge necessitates a small loading gauge. In some countries, narrow gauge is the standard: Ja ...

Wednesbury
Wednesbury ( ) is a market town in the Sandwell district, in the county of the West Midlands (county), West Midlands, England; it was historically in Staffordshire. It is located near the source of the River Tame, West Midlands, River Tame and is part of the Black Country. Wednesbury is situated 5 miles (8km) south-east of Wolverhampton, 3 miles (4.4km) south-west of Walsall and 7 miles (11.8km) north-west of Birmingham.

History Medieval and earlier The substantial remains of a large ditch excavated in St Mary's Road in 2008, following the contours of the hill and predating the Early Medieval period, has been interpreted as part of a hilltop enclosure and possibly the Iron Age hillfort long suspected on the site. The first authenticated spelling of the name was Wodensbyri, written in an endorsement on the back of the copy of the will of Wulfric Spot, dated 1004. Wednesbury (" ...

Miller Platform
The Miller platform was an innovative railroad passenger car platform of the 19th century designed to prevent the hazard of telescoping in railroad collisions. It was named for its U.S. inventor, Ezra L. Miller, who was issued a patent for it on July 24, 1866. The platform was part of an assembly which included a new type of coupler called the Miller hook which came to replace the older link-and-pin coupler.

Trams In Krefeld
The Krefeld tramway network () is a network of tramways forming part of the public transport system in Krefeld, a city in the federal state of North Rhine-Westphalia, Germany. Opened in 1883, the network has been operated since 2002 by SWK MOBIL, and is integrated in the Verkehrsverbund Rhein-Ruhr (VRR). Lines , the Krefeld tramway network had four lines, operating in Krefeld and St.Tönis. All of these lines, along with lines ''U70'' and ''U76'' of the Düsseldorf-Krefeld Stadtbahn, run through the centre of Krefeld, on a combined double track route via Ostwall, using four rails per track (two of them metre gauge, and the other two standard gauge). Tram lines (as of June 2013) In the evenings, all tram lines run to about 24:00, and in the early hours of Saturdays and Sundays, lines 041, 042 and 044 continue running until 03:30.

6 (six) is the natural number following 5 and preceding 7. It is a composite number and the smallest perfect number. In mathematics A six-sided polygon is a hexagon, one of the three regular polygons capable of tiling the plane. A hexagon also has 6 edges as well as 6 internal and external angles. 6 is the second smallest composite number. It is also the first number that is the sum of its proper divisors, making it the smallest perfect number. It is also the only perfect number that doesn't have a digital root of 1. 6 is the first unitary perfect number, since it is the sum of its positive proper unitary divisors, without including itself. Only five such numbers are known to exist. 6 is the largest of the four all-Harshad numbers. 6 is the 2nd superior highly composite number, the 2nd colossally abundant number, the 3rd triangular number, the 4th highly composite number, a pronic number, a congruent number, a harmonic divisor number, and a semiprime. 6 is also the ...

Panama Canal
The Panama Canal () is an artificial waterway in Panama that connects the Caribbean Sea with the Pacific Ocean. It cuts across the narrowest point of the Isthmus of Panama, and is a Channel (geography), conduit for maritime trade between the Atlantic and Pacific Oceans. Lock (water navigation), Locks at each end lift ships up to Gatun Lake, an artificial fresh water lake Above mean sea level, above sea level, created by damming the Chagres River and Lake Alajuela to reduce the amount of excavation work required for the canal. Locks then lower the ships at the other end. An average of of fresh water is used in a single passing of a ship. The canal is threatened by low water levels during droughts. The Panama Canal shortcut greatly reduces the time for ships to travel between the Atlantic and Pacific oceans, enabling them to avoid the lengthy, hazardous route around the southernmost tip of South America via the Drake Passage, the Strait of Magellan or the Beagle Channel. Its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panama Canal Locks
The Panama Canal locks () are a Canal lock, lock system that lifts ships up to the main elevation of the Panama Canal and lowers them down again. The original canal had a total of six steps (three up, three down) for a ship's passage. The total length of the lock structures, including the approach walls, is over . The locks were one of the greatest engineering works ever to be undertaken when they opened in 1914. No other concrete construction of comparable size was undertaken until the Hoover Dam, in the 1930s. There are two independent transit lanes, since each lock is built double. The size of the original locks limits the maximum size of ships that can transit the canal; this size is known as Panamax. Construction on the Panama Canal expansion project, which included a third set of locks, began in September 2007, finished by May 2016 and began commercial operation on June 26, 2016. The new locks allow transit of larger, New Panamax ships, which have a greater cargo capacity ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
