Siemens SD-460
The 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 DÜWAG and assembled at both DÜWAG's factory in Düsseldorf, West Germany (Germany after reunification in 1990) and the Siemens factory in Florin, California. Siemens purchased DÜWAG 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 three doors on each side for level boarding at high-platform stations and one door with steps for boarding at street-level. The SD-400 was manufactured and marketed alongside the older Siemens–Duewag U2 LRV and the SD-460 was manufactured and marketed alongside the Siemens SD-100 and ...

Pennsylvania Trolley Gauge
Originally, various track gauges were used in the United States. Some railways, primarily in the northeast, used standard gauge of ; others used gauges ranging from to . As a general rule, southern railroads were built to one or another broad gauge, mostly , while northern railroads that were not standard-gauge tended to be narrow-gauge. The Pacific Railroad Acts of 1863 specified standard gauge. Notable exceptions were the railroads that predominated in the first part of the 19th century in New York State, and the lines centered on Portland, Maine. Problems began as soon as lines began to meet, and standard gauge was adopted in much of the northeastern U.S. Standard gauge had spread widely across the country by the late 19th century except in some parts of the South; it was adopted there in a two-day changeover on May 31-June 1, 1886. Today, standard gauge is used almost everywhere in the U.S. Non-standard gauges remain in use only for some municipal and regional mass tran ...

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 of Tram Designs 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bogie
A bogie ( ) (in some senses called a truck in North American English) is a chassis or framework that carries a wheelset, attached to a vehicle—a modular subassembly of wheels and axles. 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 the dolly in a road train or in railway bogie exchange); it may contain a suspension within it (as most rail and trucking bogies do), or be solid and in turn be suspended (as most bogies of tracked vehicles are); 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). In Scotland, the term is used for a child’s (usually home-made) wooden cart. While ''bogie'' is the preferred spelling and first-listed variant in various dictionaries, bogey and bogy are also used. ...

August 2009 Pittsburgh LRT Interior
August is the eighth month of the year in the Julian and Gregorian calendars, and the fifth of seven months to have a length of 31 days. Its zodiac sign is Leo and was originally named ''Sextilis'' in Latin because it was the 6th month in the original ten-month Roman calendar under Romulus in 753 BC, with March being the first month of the year. About 700 BC, it became the eighth month when January and February were added to the year before March by King Numa Pompilius, who also gave it 29 days. Julius Caesar added two days when he created the Julian calendar in 46 BC (708 AUC), giving it its modern length of 31 days. In 8 BC, it was renamed in honor of Emperor Augustus. According to a Senatus consultum quoted by Macrobius, he chose this month because it was the time of several of his great triumphs, including the conquest of Egypt. Commonly repeated lore has it that August has 31 days because Augustus wanted his month to match the length of Julius Caesar's July, ...

Siemens S70
The Siemens S70, its successor the S700 and European variant, the Avanto, are a series of low-floor light-rail vehicles (LRV) and streetcars manufactured by Siemens Mobility, a division of German conglomerate Siemens AG. The S70 and S700 are built for the United States market where the vehicles are in use on several light rail and streetcar systems. The S70 was manufactured from 2002 to 2017 and the S700 from 2014 to present, but the model designation ''S700'' was only introduced in 2019 and then retroactively applied to certain versions of the S70 built in earlier years. In this field, it competes mainly with Bombardier and Kinki Sharyo low-floor LRVs and modern streetcars manufactured by Inekon and Brookville Equipment Corporation. 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 of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siemens SD-100 And SD-160
The SD-100 and SD-160 are light rail vehicles (LRV) that were manufactured by Siemens Mobility between 1992 and 2013 for the North American market. The vehicles were all constructed at the Siemens facility in Florin, California. The primary difference between the models is that the older SD-100 uses direct current motors, while the newer SD-160 uses alternating current motors. Both models were built with a "high-floor" design and could be equipped for level boarding at high-platform stations or with steps and wheelchair lifts for passenger loading at street level. This model was manufactured and marketed alongside the Siemens SD-400 and SD-460 LRV, which offered both level boarding at high-platform stations and steps for passenger loading at street level. This model has been replaced by the Siemens S700 and S70, a low-floor LRV for passenger loading at street level and the Siemens S200, a high-floor LRV for level boarding at high-platform stations.

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 mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DC Motor
A DC motor is any of a class of rotary electrical motors that converts direct current (DC) electrical energy into mechanical energy. The most common types rely on the forces produced by induced magnetic fields due to flowing current in the coil. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current in part of the motor. DC motors were the first form of motors widely used, as they could be powered from existing direct-current lighting power distribution systems. A DC motor's speed can be controlled over a wide range, using either a variable supply voltage or by changing the strength of current in its field windings. Small DC motors are used in tools, toys, and appliances. The universal motor, a lightweight brushed motor used for portable power tools and appliances can operate on direct current and alternating current. Larger DC motors are currently used in propulsion of electric vehicl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Direct Current
Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or '' voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alternating current via an inverter. Direct current has many uses, from the charging of batteries to large power ...
