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 This model has been replaced by the Siemens S700 and S70, a low-floor LRV for passenger loading at street level and the Siemens S200, a high-floor LRV for level boarding at high-platform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.

San Diego Trolley
The San Diego Trolley is a light rail system operating in the metropolitan area of San Diego. It is known colloquially as "The Trolley". The Trolley's operator, San Diego Trolley, Inc. (SDTI), is a subsidiary of the San Diego Metropolitan Transit System (MTS). The Trolley began service on July 26, 1981, making it the oldest of the second-generation light rail systems in the United States. The Trolley system serves 62 stations, comprises of route, three primary lines ( Blue Line, Orange Line, and Green Line) that operate daily, and one heritage line ( Silver Line) that operates on a circuit of downtown on select days.

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 sup ...

Kilowatt
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). : ...

Edmonton Transit Service
The Edmonton Transit Service (ETS) (previously known as Edmonton Transit System) is the public transit service owned and operated by the City of Edmonton in Alberta, Canada. It operates Edmonton's bus and light rail systems. In , the system had a ridership of , or about per weekday as of . History Edmonton Transit Service began operations on 30 October 1908, under the name ''Edmonton Radial Railway'' (ERR), and alternatively as the ''Edmonton Radial Tramway''. Also in 1908, ERR acquired the ''Strathcona Radial Tramway Company Limited,'' and also began servicing the villages of North Edmonton and Calder. The transit service's name was changed to ''Edmonton Transportation Service'' in July 1946, but just a year later it was re-named to ''Edmonton Transit System.'' The service was re-named to ''Edmonton Transit Service'' in 2016. Former systems Streetcars The ''Edmonton Radial Railway'' (ERR) began operations in 1908, both in the City of Edmonton and the neighbouring City ...

CTrain
CTrain (previously branded C-Train) is a light rail rapid transit system in Calgary, Alberta, Canada. Most of the network functions as a light metro, though in the free-fare zone that runs through the downtown core the Red and Blue lines operate like a urban tramway (this transition occurs due to the density of stations in the free-fare zone, and is possible due to the design of the rail vehicles and their ability to operate on both segregated and road-integrated tracks). The CTrain began operation on May 25, 1981 and has expanded as the city has increased in population. The system is operated by Calgary Transit, as part of the Calgary municipal government's transportation department. In , the system had a ridership of , or about per weekday as of , making it one of the busiest light rail transit systems in North America. About 45% of workers in Downtown Calgary take the CTrain to work. History The idea of rail transit in Calgary originated in a 1967 Calgary transportatio ...

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 ...
