European Rail Traffic Management System
The European Rail Traffic Management System (ERTMS) is the system of standards for management and interoperation of signalling for railways by the European Union (EU). It is conducted by the European Union Agency for Railways (ERA) and is the organisational umbrella for the separately managed parts of * GSM–R (communication), * European Train Control System (ETCS, signalling), * European Train Management Layer (ETML, payload management) The main target of ERTMS is to promote the interoperability of trains in the EU. It aims to greatly enhance safety, increase efficiency of train transports and enhance cross-border interoperability of rail transport in Europe. This is done by replacing former national signalling equipment and operational procedures with a single new Europe-wide standard for train control and command systems. The development process was started with the technical foundations for communication (GSM-R) and signalling (ETCS). Both are well established and in ad ...

Governmental Organization
A government agency or state agency, sometimes an appointed commission, is a permanent or semi-permanent organization in the machinery of government (bureaucracy) that is responsible for the oversight and administration of specific functions, such as an Administration (government), administration. There is a notable variety of agency types. Although usage differs, a government agency is normally distinct both from a department or Ministry (government department), ministry, and other types of public body established by government. The functions of an agency are normally executive in character since different types of organizations (''such as commissions'') are most often constituted in an advisory role — this distinction is often blurred in practice however, it is not allowed. A government agency may be established by either a national government or a state government within a federal system. Agencies can be established by legislation or by executive powers. The autonomy, indep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homologation
Homologation (Greek language, Greek ''homologeo'', ὁμολογέω, "to agree") is the granting of approval by an official authority. This may be a court of law, a government department, or an academic or professional body, any of which would normally work from a set of rules or standards to determine whether such approval should be given. The word may be considered very roughly synonymous with ''wiktionary:Accreditation, accreditation'', and in fact in French language, French and Spanish language, Spanish may be used with regard to academic degrees (see apostille). ''Certification'' is another possible synonym, while ''to homologate'' is the infinitive verb form. In today's marketplace, for instance, products must often be homologated by some public agency to assure that they meet standards for such things as safety and environmental impact. A court action may also sometimes be homologated by a judicial authority before it can proceed, and the term has a precise legal meaning i ...

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 ...

5 Ft And 1520 Mm Gauge Railways
Railways with a railway track track gauge, gauge of first appeared in the United Kingdom and the United States. This gauge became commonly known as "Russian gauge", because the government of the Russian Empire chose it in 1843. Former areas and states (such as Grand Duchy of Finland, Finland) of the Empire have inherited this standard. However in 1970, Rail transport in the Soviet Union, Soviet Railways re-defined the gauge as 1,520 mm (). With about of track, 1,520 mm is the second-most common gauge in the world, after . History Great Britain, 1748 In 1748, the Wylam waggonway was built to a gauge for the shipment of coal from Wylam to Lemington down the River Tyne. In 1839, the Eastern Counties Railway was constructed. In 1840, the Northern and Eastern Railway was built. In 1844, both lines were Track gauge conversion, converted to . In 1903, the East Hill Cliff Railway, a funicular, was opened. United States, 1827 In 1827, Horatio Allen, the chief en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
