Siemens SD-400 And SD-460
The Siemens SD-400 and SD-460 are light rail vehicles (LRV) that were manufactured by Siemens Mobility between 1985 and 2005 for the North and South American markets. The SD-400 was built under Siemens' joint venture with Duewag and assembled at both Duewag's factory in Düsseldorf, West Germany (Germany after reunification in 1990) and the Siemens factory in Florin, California. Siemens purchased Duewag in 1999 and the SD-460 was assembled entirely at the Siemens factory in California. The primary difference between the models is that the older SD-400 uses direct current motors, while the newer SD-460 uses alternating current motors. Both models were built with a "high-floor" design and equipped with 3-4 doors on each side for level boarding at high-platform stations and one door with steps for boarding at street-level. The SD-400 and SD-460 were manufactured and marketed alongside the older Siemens–Duewag U2 LRV and later the Siemens SD-100 and SD-160 vehicles. The U2, ...

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] |

Level Boarding
Various terms are used for passenger railway lines and equipment; the usage of these terms differs substantially between areas: Rapid transit A rapid transit system is an electric railway characterized by high speed (~) and rapid acceleration. It uses passenger railcars operating singly or in multiple unit trains on fixed rails. It operates on separate right-of-way (transportation), rights-of-way from which all other vehicular and foot traffic are excluded (i.e. is fully grade separation, grade-separated from other traffic). The APTA definition also includes the use sophisticated railway signalling, signaling systems, and railway platform height, high platform loading. Originally, the term ''rapid transit'' was used in the 1800s to describe new forms of quick urban public transportation that had a right-of-way separated from street traffic. This set rapid transit apart from horsecars, trams, streetcars, bus, omnibuses, and other forms of public transport. A variant of the ter ...

Articulated Tram
Trams have been used since the 19th century, and since then, there have been various uses and designs for trams around the world. This article covers the many design types, most notably the articulated, double-decker, drop-centre, low-floor, single ended, double-ended, rubber -tired, and tram-train; and the various uses of trams, both historical and current, most notably cargo trams, a dog car, hearse tram, maintenance trams, a mobile library service, a nursery tram, a restaurant tram, a tourist tram, and as mobile offices. Types Articulated Articulated trams, invented and first used by the Boston Elevated Railway in 1912–13 at a total length of about twelve meters long (40 ft) for each pioneering example of twin-section articulated tram car, have two or more body sections, connected by flexible joints and a round platform at their pivoting midsection(s). Like articulated buses, they have increased passenger capacity. In practice, these trams can be up to long ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

(or unit) wheel arrangements that was developed by the Association of American Railroads. Essentially a simplification of the European UIC classification, it is widely used in North America to describe Diesel locomotive, diesel and electric locomotives (including third-rail electric locomotives). It is not used for steam locomotives, which use the Whyte notation instead (except geared steam locomotives, which are instead classified by their model and their number of trucks). The AAR system (like UIC) counts axles, unlike Whyte, which counts wheels. Letters refer to powered axles, and numbers to unpowered (or idler) axles. "A" refers to one powered axle, "B" to t ...

Siemens S700 And S70
The Siemens S70 and its successor, the Siemens S700, are a series of articulated low-floor light-rail vehicles (LRV) and modern streetcars manufactured for the United States market by Siemens Mobility, a division of German conglomerate Siemens AG. The series also includes a European tram-train variant, the Siemens Avanto. The S70 was manufactured from 2002 to 2017 and the improved S700 from 2014 to present, but the latter model designation was only introduced in 2019 and then retroactively applied to certain versions of the S70 built in earlier years. In this market, it competes mainly with Alstom and Kinki Sharyo low-floor LRVs and streetcars manufactured by Brookville and Inekon. The Avanto was built for the European market starting in 2006 and was principally sold to tram-train systems which, in whole or part, share their tracks with heavy rail trains. In Europe, the Siemens Combino and Avenio models are the preferred offerings for purely light rail or tramway systems ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Siemens–Duewag U2
The Siemens–Duewag U2 is a type of light rail vehicle (LRV), built by consortium of Siemens, Duewag and Wegmann & Co built between 1968 and 1990. The design was based on the prototype U1 tram built in 1965 for the Frankfurt U-Bahn. The U2 was also designed for and used by the Frankfurt U-Bahn. The name is derived from the class identifier given to the cars in the Frankfurt. The U2 was later exported to North America and adapted for use on light rail systems in Edmonton, Calgary, and San Diego, during a period in which few purpose-built LRVs were being manufactured. History U1 prototype In the early 1960s, Duewag developed and manufactured a prototype of a new tram for the Frankfurt U-Bahn. The design was largely based on the previously delivered trams, but added electronic controls that allowed several railcars to be coupled together to form trains, and a floor height of that made it possible to board from platforms with a height of without having to add a folding step previ ...

AC Motor
An AC motor is an electric motor driven by an alternating current (AC). The AC motor commonly consists of two basic parts, an outside stator having coils supplied with alternating current to produce a rotating magnetic field, and an inside rotor attached to the output shaft producing a second rotating magnetic field. The rotor magnetic field may be produced by permanent magnets, reluctance saliency, or DC or AC electrical windings. Less common, AC linear motors operate on similar principles as rotating motors but have their stationary and moving parts arranged in a straight line configuration, producing linear motion instead of rotation. Operating principles The two main types of AC motors are induction motors and synchronous motors. The induction motor (or asynchronous motor) always relies on a small difference in speed between the stator rotating magnetic field and the rotor shaft speed called slip to induce rotor current in the rotor AC winding. As a result, the induction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
