Sectional Appendix
In Great Britain, the Sectional Appendix is a railway document compiled by Network Rail and is the official definition of railway infrastructure, giving a detailed description of all railway lines owned by Network Rail. It has traditionally been published in printed format, originally as a bound book and subsequently in loose-leaf format, for ease of updating. History In earlier years, instructions to traincrews relating to the operation of the railway were included within the working timetables. As the volume of instructions increased, they later came to be published in a separate document, known in full as the ''"Sectional Appendix to the Working Timetable"'' or similar. Content There are modules for different areas, e.g. KSW2 covers Kent and Sussex. Each module may be divided in a similar way to the following sections: Section 1: Route Module ;Maps Outline maps providing a general overview of the route showing lines, station names, and reference numbers. The number ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Britain Railway Technical Manuals
{{Citations needed, date=May 2020 The railway network of Great Britain is operated with the aid of a number of documents, which have been sometimes termed "technical manuals", because they are more detailed than the pocket-timetables which the public encounters every day. Historically, they were classified ''PRIVATE and not for publication'', however since rail privatisation they are now more widely available, mostly in digital form, because they are produced centrally and not by the regional rail operators. Documents of relevance to passengers Distributed by National Rail Enquiries *The National Rail Conditions of Travel, which set out the customer's rights and responsibilities when travelling on the National Rail network. Every ticket purchased is a contract, and this document is the terms of that contract. It is produced by the Rail Settlement Plan, part of the Rail Delivery Group. It ''must'' be available for inspection at any ticket office selling tickets otherwise ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Railway
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facilit ...

Loose-leaf
A loose leaf is a piece of paper of any kind that is not bound in place, or available on a continuous roll, and may be punched so as to be organized in a ring binder. Loose leaf paper may be sold as free sheets, or made up into notepads, where perforations or glue allow them to be removed easily. "Leaf" in many languages refers to a sheet or page of paper, as in Folio, ''as in feuille de papier'' (French), ''hoja de papel'' (Spanish), ''foglio di carta'' (Italian). Description "Loose leaf" describes any kind of paper or book that is available in single sheets, unbound. Its "leaves", or sheets, are "loose" and not bound in notebook or book form. ''However'', it seems "loose leaf" in the USA's Midwest (and this entry) refers most specifically to a lined and punched paper, or ruled paper, a school supply also known as "binder paper" that can be sorted in a loose leaf binder. This may be a typical 3 ring binder but "loose leaves" of other types can also go in a date book, address b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Working Timetable
A working timetable (WTT) - (Fr. ''horaire de service (HDS)'' or ''service annuel (SA)''; N. America ''Employee timetable'') - The data defining all planned train and rolling-stock movements which will take place on the relevant infrastructure during the period for which it is in force; within the EU, it is established once per calendar year. The trains included may be passenger trains, freight trains, empty stock movements, or even bus and/or ship connections or replacements. Contents The detail found in Working Timetables includes the timings at every major station, junction, or other significant location along the train's journey (including additional minutes inserted to allow for such factors as engineering work or particular train performance characteristics), which platforms are used at certain stations, and line codes where there is a choice of running line. Further information may include the train's identification (or "reporting") number which, in Network Rail practice, c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cab Secure Radio
Cab Secure Radio (CSR) was an in-cab analogue radiotelephone system formerly used on parts of the British railway network. Its main function was to provide a secure speech link between the train driver and the signaller which could not be overheard by other train drivers. In areas where CSR was used, it had to be the primary method of communication between driver and signaller, always being used in preference to the ''signal post telephone''. CSR was replaced by the GSM-R digital system, forming the initial phase of rollout of ERTMS throughout the UK. History CSR was first introduced in the Glasgow area in 1986 to enable driver-only operation of trains. It was later used in the London and Liverpool areas. In the Railway rule book, there is provision for a driver stopped at a red signal to disembark the train and access a track-side telephone in order to talk to the signaller. This might be occasioned by a scenario where there was a track circuit failure and the signals had ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GSM-R
GSM-R, Global System for Mobile Communications – Railway or GSM-Railway is an international wireless communications standard for railway communication and applications. A sub-system of European Rail Traffic Management System (ERTMS), it is used for communication between train and railway regulation control centers. The system is based on GSM and ''EIRENE – MORANE'' specifications which guarantee performance at speeds up to 500 km/h (310 mph), without any communication loss. GSM-R could be supplanted by LTE-R, with the first production implementation being in South Korea. However, LTE is generally considered to be a " 4G" protocol, and the UIC's Future Railway Mobile Communication System (FRMCS) program is considering moving to something " 5G"-based (specifically 3GPP R15/16), thus skipping two technological generations. History GSM-R is built on GSM technology, and benefits from the economies of scale of its GSM technology heritage, aiming at being a cost ...

Traction Current
A railway electrification system supplies electric power to railway trains and trams without an on-board prime mover or local fuel supply. Electric railways use either electric locomotives (hauling passengers or freight in separate cars), electric multiple units (passenger cars with their own motors) or both. Electricity is typically generated in large and relatively efficient generating stations, transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and transmission lines, but most purchase power from an electric utility. The railway usually provides its own distribution lines, switches, and transformers. Power is supplied to moving trains with a (nearly) continuous conductor running along the track that usually takes one of two forms: an overhead line, suspended from poles or towers along the track or from structure or tunnel ceilings, or a third rail mounted at track level and contacted by a s ...

Geographical Mile
The geographical mile is a unit of length determined by 1 minute of arc along the Earth's equator. For the international ellipsoid 1924 this equalled 1855.4 metres. ''The American Practical Navigator'' 2017 defines the geographical mile as . Greater precision depends more on choice of ellipsoid than on more careful measurement: the length of the equator in the World Geodetic System WGS-84 is , which makes the geographical mile 1855.3248 m,. Equatorial radius = 6,378,137 m. while the '' IERS Conventions (2010)'' takes the equator to be , making the geographical mile 1855.3247 m,. Equatorial radius = 6,378,136.6 m. 0.1 millimetres shorter. In any ellipsoid, the length of a degree of longitude at the equator is thus exactly 60 geographical miles. The shape of the Earth is a slightly flattened sphere, which results in the Earth's circumference being 0.168% larger when measured around the equator as compared to through the poles. The geographical mile is slightly larger than the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chain (length)
The chain is a unit of length equal to 66 feet (22 yards). It is subdivided into 100 links (PDF) or 4 rods. There are 10 chains in a furlong, and 80 chains in one statute mile. In metric terms, it is 20.1168 m long. By extension, chainage (running distance) is the distance along a curved or straight survey line from a fixed commencing point, as given by an odometer. The chain has been used for several centuries in England and in some other countries influenced by English practice. In the United Kingdom, there were 80 chains to the mile, but until the early nineteenth century the Scottish and Irish customary miles were longer than the statute mile; consequently a Scots chain was about 74 (imperial) feet, an Irish chain 84 feet. These longer chains became obsolete following the adoption of the imperial system of units in 1824. Definition The UK statute chain is 22 yards, which is . This unit is a statute measure in the United Kingdom, defined in the Weights and Measures Act 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Online
In computer technology and telecommunications, online indicates a state of connectivity and offline indicates a disconnected state. In modern terminology, this usually refers to an Internet connection, but (especially when expressed "on line" or "on the line") could refer to any piece of equipment or functional unit that is connected to a larger system. Being online means that the equipment or subsystem is connected, or that it is ready for use. "Online" has come to describe activities performed on and data available on the Internet, for example: "online identity", "online predator", "online gambling", "online game", "online shopping", "online banking", and "online learning". Similar meaning is also given by the prefixes "cyber" and "e", as in the words " cyberspace", "cybercrime", "email", and "ecommerce". In contrast, "offline" can refer to either computing activities performed while disconnected from the Internet, or alternatives to Internet activities (such as shopping in br ...
