Multiple Unit
A multiple-unit train or simply multiple unit (MU) is a self-propelled train composed of one or more carriages joined together, which when coupled to another multiple unit can be controlled by a single driver, with multiple-unit train control. Although multiple units consist of several carriages, single self-propelled carriages – also called railcars, rail motor coaches or railbuses – are in fact multiple-units when two or more of them are working connected through multiple-unit train control (regardless if passengers can walk between the units or not). History Multiple-unit train control was first used in electric multiple units in the 1890s. The Liverpool Overhead Railway opened in 1893 with two-car electric multiple units, controllers in cabs at both ends directly controlling the traction current to motors on both cars. The multiple-unit traction control system was developed by Frank Sprague and first applied and tested on the South Side Elevated Railroad (n ...

Class 379
The British Rail Class 379 ''Electrostar'' is an electric multiple-unit (EMU) passenger train designed and built by the rolling-stock manufacturer Bombardier Transportation. The trains are part of the company's extensive Electrostar family. The Class 379 was specifically procured in response to a government white paper issued in 2007, under which £185 million of investment was issued to the West Anglia Main Line (WAML), the bulk of which was spent with Bombardier Transportation to procure the 30-strong Class 379 fleet of EMUs. While the type was largely intended to increase capacity, its introduction did enable the withdrawal of ageing units such as the Class 317 EMUs; the programme also involved various infrastructure improvements. The Class 379's introduction was relatively smooth and brought about a noticeable step up in service quality. Since their introduction during early 2011, the Class 379 became the principal type operated on the Stansted Express service; it was also ...

British Rail Class 321
The British Rail Class 321 are electric multiple unit (EMU) passenger trains built by British Rail Engineering Limited's Holgate Road carriage works in three batches between 1988 and 1991. The class uses alternating current (AC) overhead electrification. The design was successful and led to the development of the similar Class 320 and Class 322. Today the class is operated by Greater Anglia. Some have been converted to Class 320 and are operated by ScotRail. Description Three sub-classes were built. The first two were built for the Network SouthEast sector for operation on services from London Liverpool Street and London Euston, while the third was built for Regional Railways for use on West Yorkshire Passenger Transport Executive services from Leeds.

Technical Specifications For Interoperability
A technical specification for interoperability (abbreviated as TSI) is a text provided for in European Directive 2016/797 adopted by the European Parliament and the Council of the European Union on the interoperability of the European rail system in accordance with the ordinary legislative procedure. This directive stipulates that the railway system is divided into 8 subsystems: # infrastructure # Traction energy # control command and the trackside signalling # control command and the on-board signalling # rolling stock # Traffic operation and management # Maintenance #Telematic applications for passenger and freight services. It also provides that a technical specification for interoperability (TSI) is drawn up for each subsystem. These TSIs define the essential requirements of the above-mentioned European directives for specific cases and define a set of technical requirements that apply to new subsystems put into service. These requirements constitute a set of conditions ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Air Conditioning
Air conditioning, often abbreviated as A/C or AC, is the process of removing heat from an enclosed space to achieve a more comfortable interior environment (sometimes referred to as 'comfort cooling') and in some cases also strictly controlling the humidity of internal air. Air conditioning can be achieved using a mechanical 'air conditioner' or alternatively a variety of other methods, including passive cooling or ventilative cooling. Air conditioning is a member of a family of systems and techniques that provide heating, ventilation, and air conditioning (HVAC). Heat pumps are similar in many ways to air conditioners, but use a reversing valve to allow them to both heat and also cool an enclosed space. Air conditioners, which typically use vapor-compression refrigeration, range in size from small units used within vehicles or single rooms to massive units that can cool large buildings. Air source heat pumps, which can be used for heating as well as cooling, are becoming ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cantilever
A cantilever is a rigid structural element that extends horizontally and is supported at only one end. Typically it extends from a flat vertical surface such as a wall, to which it must be firmly attached. Like other structural elements, a cantilever can be formed as a beam, plate, truss, or slab. When subjected to a structural load at its far, unsupported end, the cantilever carries the load to the support where it applies a shear stress and a bending moment. Cantilever construction allows overhanging structures without additional support. In bridges, towers, and buildings Cantilevers are widely found in construction, notably in cantilever bridges and balconies (see corbel). In cantilever bridges, the cantilevers are usually built as pairs, with each cantilever used to support one end of a central section. The Forth Bridge in Scotland is an example of a cantilever truss bridge. A cantilever in a traditionally timber framed building is called a jetty or forebay. In ...
