Single Track (rail)
A single-track railway is a railway where trains traveling in both directions share the same track. Single track is usually found on lesser-used rail lines, often branch lines, where the level of traffic is not high enough to justify the cost of constructing and maintaining a second track. Advantages and disadvantages Single track is significantly cheaper to build and maintain, but has operational and safety disadvantages. For example, a single-track line that takes 15 minutes to travel through would have capacity for only two trains per hour in each direction safely. By contrast, a double track with signal boxes four minutes apart can allow up to 15 trains per hour in each direction safely, provided all the trains travel at the same speed. This hindrance on the capacity of a single track may be partly overcome by making the track one-way on alternate days, if the single track is not used for public passenger transit. Long freight trains are a problem if the passing s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Train To Kyle Of Lochalsh - Geograph
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a v ...

Great Britain
Great Britain is an island in the North Atlantic Ocean off the northwest coast of continental Europe. With an area of , it is the largest of the British Isles, the largest European island and the ninth-largest island in the world. It is dominated by a maritime climate with narrow temperature differences between seasons. The 60% smaller island of Ireland is to the west—these islands, along with over 1,000 smaller surrounding islands and named substantial rocks, form the British Isles archipelago. Connected to mainland Europe until 9,000 years ago by a landbridge 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 third-most-populous island after Java in Indonesia and Honshu in Japan. The term "Great Britain" is often used to refer to England, Scotland and Wales, including their component adjoining islands. Great Britain and Northern Ireland now constitute the ...

Rail Trail
A rail trail is a shared-use path on railway right of way. Rail trails are typically constructed after a railway has been abandoned and the track has been removed, but may also share the right of way with active railways, light rail, or streetcars (rails with trails), or with disused track. As shared-use paths, rail trails are primarily for non-motorized traffic including pedestrians, bicycles, horseback riders, skaters, and cross-country skiers, although snowmobiles and ATVs may be allowed. The characteristics of abandoned railways—gentle grades, well-engineered rights of way and structures (bridges and tunnels), and passage through historical areas—lend themselves to rail trails and account for their popularity. Many rail trails are long-distance trails, while some shorter rail trails are known as greenways or linear parks. Rail trails around the world Americas Bermuda The Bermuda Railway ceased to operate as such when the only carrier to exist in Bermuda folded in 1948. ...

Cross-platform Interchange
A cross-platform interchange is a type of interchange between different lines at a metro (or other railway) station. The term originates with the London Underground; such layouts exist in other networks but are not commonly so named. In the United States, it is often referred to as a cross-platform transfer. This configuration occurs at a station with island platforms, with a single platform in between the tracks allocated to two directions of travel, or two side platforms between the tracks, connected by level corridors. The benefit of this design is that passengers do not need to use stairs to another platform level for transfer. A cross-platform interchange arrangement may be costly to build due to the complexity of rail alignment, especially if the railway designers also arrange the track with flyovers (which is typically done to increase efficiency). A typical bidirectional cross-platform interchange configuration consists of two outbound directions of two different lines ...

Ormskirk Railway Station
Ormskirk railway station in Ormskirk, Lancashire, England, is a cross-platform interchange between Merseyrail services from Liverpool Central and Northern Trains services from Preston on the Ormskirk branch line, northeast of Liverpool. The station building and three arch road bridge are both Grade II listed structures. History The station was built by the East Lancashire Railway's Liverpool, Ormskirk and Preston Junction section, and opened on 2 April 1849. From 13 May 1859, the station was owned by the Lancashire and Yorkshire Railway. From 1 January 1923 the station was owned by the London, Midland and Scottish Railway. British Railways nationalised all railways on 1 January 1948 and the station became part of the London Midland Region. A branch line to via was opened by the ELR in March 1858 shortly before it was absorbed by the L&YR – this left the main line to Preston just to the north of the station. The line from Liverpool was subsequently electrified in 1913, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kirkby Railway Station
Kirkby railway station is situated in Kirkby, Merseyside, England. The station is an interchange between Merseyrail services from Liverpool Central and Northern services from Manchester Victoria via Wigan Wallgate. It is situated 7.5 miles (12 km) north-east of Liverpool Central and is the operational terminus of both the Kirkby branch of Merseyrail's Northern Line and the Kirkby Branch Line from Wigan. History The original station was built in 1848, as part of the Liverpool and Bury Railway (later part of the Lancashire and Yorkshire Railway system). The station was situated on the western side of the bridge that bisects the site and consisted of two platforms. The L&BR subsequently became part of the main L&YR route between Manchester Victoria & "Disused Stations - Liverpool Exchange ''D ...

Kirkby Station - Geograph
Kirkby ( ) is a town in the Metropolitan Borough of Knowsley, Merseyside, England. The town, historically in Lancashire, has a size of is north of Huyton and north-east of Liverpool. The population in 2016 was 41,495 making it the largest in Knowsley and the 9th biggest settlement in Merseyside. Evidence of Bronze Age activity has been noted though the first direct evidence of a settlement dates to 1086 via the Doomsday Book. The town was mainly farmland until the mid-20th century due to building of ROF Kirkby, the largest Royal Ordanance Factory filling munitions. In November 2020, Liverpool F.C. relocated its training facilities from the Melwood site in West Derby, to the town following the completion of the new AXA Training Centre. History It is believed that Kirkby was founded around 870 AD, due to archaeological evidence of Bronze Age settlement. Historically, it has been part of Lancashire.

Electrical Telegraph
Electrical telegraphs were point-to-point text messaging systems, primarily used from the 1840s until the late 20th century. It was the first electrical telecommunications system and the most widely used of a number of early messaging systems called ''telegraphs'', that were devised to communicate text messages quicker than physical transportation. Electrical telegraphy can be considered to be the first example of electrical engineering. Text telegraphy consisted of two or more geographically separated stations, called telegraph offices. The offices were connected by wires, usually supported overhead on utility poles. Many different electrical telegraph systems were invented, but the ones that became widespread fit into two broad categories. The first category consists of needle telegraphs in which a needle pointer is made to move electromagnetically with an electric current sent down the telegraph line. Early systems used multiple needles requiring multiple wires. The first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Radio Electronic Token Block
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 ...
