Siemens-Duewag Supertram
The Siemens-Duewag Supertram is a fleet of 25 trams built by Siemens Mobility, Siemens-Duewag of Düsseldorf, Germany in 1992 for use on the South Yorkshire Supertram light rail network in England. They were the only trams in use on the network until the entry into service of British Rail Class 399 tram-trains in 2017. As of June 2025, all of the fleet is operational. History After undergoing trials on Düsseldorf's Rheinbahn system, the trams were delivered to Sheffield via the Rotterdam-Immingham cargo ship route. The trams are bidirectional and consist of three articulated carriages with a low-floor area of 40%. All four entrances are at low level matching the height of the platforms to provide level access. The low-floor areas have limited seating and provide space for pushchairs and wheel chairs. The high floor areas are high and can be found at the outer-end of each end carriage and in the centre carriage; they are reached by either two or three steps. Because the Su ...

Siemens Mobility
Siemens Mobility GmbH is a division of Siemens. With its global headquarters in Munich, Siemens Mobility has four core business units: Mobility Management, dedicated to rail technology and intelligent traffic systems, Railway Electrification, Rolling Stock, and Customer Services. History Innovations from the late 19th century, such as the world's first electric train, when Siemens & Halske unveiled a train in which power was supplied through the rails, and the world's first electric tram, with the implementation of 2.5-kilometer-long electric tramway located in Berlin, built at the company's own expense, cemented the use of electric power in transportation systems. In the following years, inventions such as the first electric trolleybus, mine locomotives, and the first underground railway in continental Europe (in Budapest), set the path from trams and subways to today's high-speed trains. Siemens, alongside ThyssenKrupp and Transrapid International, was part of the Germa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Rail Class 399
The British Rail Class 399 ''Citylink'' is a type of rail vehicle built by Vossloh on its Citylink platform for operation by South Yorkshire Supertram. Primarily a low-floor tram, it is also capable of being used on the National Rail network; the Class 399 is the first such tram-train to see operational use in the United Kingdom. In 2013, an order was placed with Vossloh for the construction of a batch of seven tram-trains for Supertram. It operates as a pioneering tram-train hybrid vehicle as part of an initial pilot of the operation of such vehicles. The launch of live services using the Class 399 was repeatedly delayed, reportedly due to planning and development-related difficulty experienced by Network Rail, who were responsible for the installation of additional track and other infrastructure-related changes to accommodate the tram-trains upon the heavy rail network, as well as a necessary full track replacement programme performed by Supertram. In January 2016, the first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Driving Cab
The cab, crew compartment or driver's compartment of a locomotive, or a self-propelled rail vehicle, is the part housing the train driver, fireman or secondman (if any), and the controls necessary for the locomotive or self-propelled rail vehicle's operation. Cab locations On steam locomotives, the cab is normally located to the rear of the firebox, although steam locomotives have sometimes been constructed in a cab forward configuration. camelback locomotives often had two cabs; one for the fireman at the rear of the boiler, and one for the engineer on the side of the boiler. Camelback locomotives were built with this configuration to accommodate wider fireboxes. The cab, or crew or driver's compartment of a diesel or electric locomotive will usually be found either inside a cabin attached to a hood unit or cowl unit locomotive, or forming one of the structural elements of a cab unit locomotive. On self-propelled rail vehicles, the cab may be at one or both ends. His ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fibreglass
Fiberglass (American English) or fibreglass ( Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, non- magnetic, non- conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins. Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melamine Resin
Melamine resin or melamine formaldehyde (also shortened to melamine) is a resin with melamine rings terminated with multiple hydroxyl groups derived from formaldehyde. This thermosetting plastic material is made from melamine and formaldehyde. In its butylated form, it is dissolved in n-Butanol, ''n''-butanol and xylene. It is then used to cross-link with alkyd, epoxy, Acrylic resin, acrylic, and polyester resins, used in surface coatings. There are many types, varying from very slow to very fast curing. Curing Melamine-formaldehyde can be curing (chemistry), cured by heating, which induces dehydration and crosslinking. The crosslinking can be carried out to a limited degree to give resins. Either the melamine-formaldehyde resins or melamine-formaldehyde "monomer" can be cured by treatment with any of several polyols. Applications Construction material The principal use of melamine resin is as the main constituent of high-pressure laminates, such as Formica (plastic), For ...

Public Address
A public address system (or PA system) is an electronic system comprising microphones, amplifiers, loudspeakers, and related equipment. It increases the apparent volume (loudness) of a human voice, musical instrument, or other acoustic sound source or recorded sound or music. PA systems are used in any public venue that requires that an announcer, performer, etc. be sufficiently audible at a distance or over a large area. Typical applications include sports stadiums, public transportation vehicles and facilities, and live or recorded music venues and events. A PA system may include multiple microphones or other sound sources, a mixing console to combine and modify multiple sources, and multiple amplifiers and loudspeakers for louder volume or wider distribution. Simple PA systems are often used in small venues such as school auditoriums, churches, and small bars. PA systems with many speakers are widely used to make announcements in public, institutional and commercial buildings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spring (device)
A spring is a device consisting of an Elasticity (physics), elastic but largely rigid material (typically metal) bent or molded into a form (especially a coil) that can return into shape after being compressed or extended. Springs can Energy storage, store energy when compressed. In everyday use, the term most often refers to coil springs, but there are many different spring designs. Modern springs are typically manufactured from spring steel. An example of a non-metallic spring is the Bow (weapon), bow, made traditionally of flexible Taxus baccata, yew wood, which when Bow draw, drawn stores energy to propel an arrow. When a conventional spring, without stiffness variability features, is compressed or stretched from its resting position, it exerts an opposing force approximately proportional to its change in length (this approximation breaks down for larger deflections). The ''rate'' or ''spring constant'' of a spring is the change in the force it exerts, divided by the cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vigilance Control
A dead man's switch is a switch that is designed to be activated or deactivated if the human operator becomes incapacitated, such as through death, loss of consciousness, or being bodily removed from control. Originally applied to switches on a vehicle or machine, it has since come to be used to describe other intangible uses, as in computer software. These switches are usually used as a form of fail-safe where they stop a machine with no operator from a potentially dangerous action or incapacitate a device as a result of accident, malfunction, or misuse. They are common in such applications as locomotives, Aviation fuel, aircraft refuelling, Elevator, freight elevators, lawn mowers, tractors, personal watercraft, outboard motors, chainsaws, snowblowers, treadmills, snowmobiles, amusement rides, and many medical imaging devices. On some machines, these switches merely bring the machines back to a safe state, such as reducing the throttle to idle or applying brakes while leaving t ...

Joystick
A joystick, sometimes called a flight stick, is an input device consisting of a stick that pivots on a base and reports its angle or direction to the device it is controlling. Also known as the control column, it is the principal control device in the cockpit of many civilian and military aircraft, either as a centre stick or side-stick. It has various switches to control functions of the aircraft controlled by the Pilot and First Officer of the flight. Joysticks are often used to control video games, and usually have push-buttons whose state can be read by the computer. A popular variation of the joystick used on modern video game consoles is the analog stick. Joysticks are also used for controlling machines such as cranes, trucks, underwater unmanned vehicles, wheelchairs, surveillance cameras, and Zero-turn mower, zero turning radius lawn mowers. Miniature finger-operated joysticks have been adopted as input devices for smaller electronic equipment such as mobile phones. A ...

Overhead Lines
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, Electric multiple unit, electric multiple units, trolleybuses or trams. The generic term used by the International Union of Railways for the technology is ''overhead line''. It is known variously as overhead catenary, overhead contact line (OCL), overhead contact system (OCS), overhead equipment (OHE), overhead line equipment (OLE or OHLE), overhead lines (OHL), overhead wiring (OHW), traction wire, and trolley wire. An overhead line consists of one or more wires (or Overhead conductor rail, rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regularly spaced intervals along the track. The feeder stations are usually fed from a High voltage, high-voltage Electricity distribution, electrical grid. Overview Electric trains that collect their current from overhead lines use a de ...

Bogie
A bogie ( ) (or truck in North American English) comprises two or more Wheelset (rail transport), wheelsets (two Railroad wheel, wheels on an axle), in a frame, attached under a vehicle by a pivot. Bogies take various forms in various modes of transport. A bogie may remain normally attached (as on many railroad cars and semi-trailers) or be quickly detachable (as for a dolly (trailer), dolly in a road train or in railway bogie exchange). It may include Suspension (vehicle), suspension components within it (as most rail and trucking bogies do), or be solid and in turn be suspended (as are most bogies of continuous track, tracked vehicles). It may be mounted on a swivel, as traditionally on a railway carriage or locomotive, additionally jointed and sprung (as in the landing gear of an airliner), or held in place by other means (centreless bogies). Although ''bogie'' is the preferred spelling and first-listed variant in various dictionaries, bogey and bogy are also used. Rail ...
