Single Track Railway
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. Long freight trains are a problem if the passing stretches are not long enough. Other disadvantages include the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Train To Kyle Of Lochalsh - Geograph
''The'' is a grammatical article in English, denoting nouns that are already or about to be 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 nouns 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 the archaic pronoun ''thee' ...

Token (railway Signalling)
In railway signalling, a token is a physical object which a train driver is required to have or see before entering onto a particular section of single track. The token is clearly endorsed with the names of the section to which it belongs. A token system is more commonly used for single lines because of the greater risk of collision in the event of a mistake being made by a signaller or traincrew than on double lines. Principle The operation of a bidirectional single track line has the hazard of two trains colliding. The simplest way to prevent such collisions is to have only one train in the section at any given time. Such a system is known as "one-engine-in-steam” (OES) or “one-train working" (OTW). This system is used on some branches of rail networks, and on heritage railways. The main disadvantage is that it restricts the number of train movements that can be made. For a larger railway system, it becomes exceptionally limiting in the level of operations that it all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Microstates
A European microstate or European ministate is a very small sovereign state in Europe. In modern usage, it typically refers to the six smallest states in Europe by area: Andorra, Liechtenstein, Malta, Monaco, San Marino, and Vatican City. Andorra, Liechtenstein, Monaco and Vatican City are monarchies (Vatican City is an elective monarchy ruled by the Pope). These states trace their status back to the first millennium or the early second millennium except for Liechtenstein, created in the 18th century. Microstates are small independent states recognised by larger states. According to the qualitative definition suggested by Zbigniew Dumieński (2014), microstates can also be viewed as "modern protected states, i.e. sovereign states that have been able to unilaterally depute certain attributes of sovereignty to larger powers in exchange for benign protection of their political and economic viability against their geographic or demographic constraints." In line with this definitio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Railway Of Vancouver Island
The Island Corridor, previously the Esquimalt & Nanaimo Railway (E&N Railway), is a railway operation on Vancouver Island. It is owned by the Island Corridor Foundation, a registered charity. The railway line is in length from Victoria, British Columbia, Victoria to Courtenay, British Columbia, Courtenay, known as the Victoria Subdivision, with a branch line from Parksville, British Columbia, Parksville to Port Alberni, known as the Port Alberni Subdivision, of , for a total of mainline track. In 2006, the Island Corridor Foundation acquired the railway's ownership from RailAmerica and Canadian Pacific Railway. Passenger service has been "temporarily suspended" since 2011 due to poor infrastructure condition that resulted from deferred maintenance. History Vancouver Island joining Canada The history of an island railway and a functioning island railway in perpetuity started with the Colony of British Columbia (1866–1871), colony of Vancouver Island joining British Columb ...

Rail Trail
A rail trail or railway walk is a shared-use path on a Right of way#Rail right of way, 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 rail corridor with active railways, light rail, or tram, 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 all-terrain vehicle, 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 Greenway (landscape), greenways or linear parks. Rail trails around the world Americas Bermuda The B ...

Cross-platform Interchange
A cross-platform interchange is a type of Interchange station, 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 and Canada, 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 overpass, flyovers (which is typically done to increase efficiency). A typical bidirectional cross-platform interchange configuration consists of two ou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ormskirk Railway Station
Ormskirk railway station in Ormskirk, Lancashire, England, is a cross-platform interchange between Merseyrail services from Liverpool Central railway station, Liverpool Central and Northern Trains services from Preston railway station, Preston on the Ormskirk branch line, northeast of Liverpool.

Electrical Telegraph
Electrical telegraphy is point-to-point distance communicating via sending electric signals over wire, a system 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 send text messages more quickly than physically carrying them. Electrical telegraphy can be considered the first example of electrical engineering. Electrical 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 electrical telegraph systems were invented that operated in different ways, but the ones that became widespread fit into two broad categories. First are the needle telegraphs, in which electric current sent down the telegraph line produces electromagnetic force to move a needle-shaped pointer into position o ...

Railway Signalling
Railway signalling (), or 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 ''safe-working'' (Aus.). Not all these methods require the use of p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
