Bombardier Advanced Rapid Transit
Innovia Metro is an automated rapid transit system manufactured by Alstom. Innovia Metro systems run on conventional metal rails and pull power from a third rail but are powered by a linear induction motor that provides traction by using magnetic force to pull on a "fourth rail" (a flat aluminum slab) placed between the running rails. However, newer versions of the technology are available with standard electric rotary propulsion. The design was originally developed in the 1970s by the Urban Transportation Development Corporation (UTDC), a Government of Ontario–owned crown corporation. It was designed as a system that would provide economic rapid transit service in the suburbs, which would have ridership levels between what a bus could serve at the low-end, or a subway at the high-end. During development, the system was known as the ICTS (Intermediate Capacity Transit System). The ICTS was chosen for lines in Vancouver, Toronto, and Detroit. Further sales were not forthcoming ...

Rapid KL
Rapid KL (stylized as ''rapidKL'') is a public transportation system owned by Prasarana Malaysia and operated by its subsidiaries Rapid Rail and Rapid Bus. The acronym stands for , which translates to Kuala Lumpur Integrated Rapid Transit Network in the Malay language. Rapid KL, with its of Rapid transit, metro railway and of Bus rapid transit, BRT Bus lane, carriageway, is part of the Klang Valley Integrated Transit System, operating throughout Kuala Lumpur and Selangor's Satellite city, satellite cities in the Klang Valley area. The rail transit line was opened in 1996. It was followed by a federal government restructuring of public transport systems in Kuala Lumpur in the early 2000s after the bankruptcy of STAR and PUTRA Light Rapid Transit operators, the precursors to the Ampang and Sri Petaling lines, Ampang/Sri Petaling Lines and Kelana Jaya Line respectively, and the creation of the Rapid KL brand. In 2003, it had inherited bus services and assets formerly operated a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Line 3 Scarborough
Line 3 Scarborough, originally known as Scarborough RT (the SRT), was a medium-capacity rapid transit line that was part of the Toronto subway system of the Toronto Transit Commission in Toronto, Ontario, Canada. The line ran entirely within the eastern district of Scarborough, encompassing six stations and of mostly elevated track. It was connected with Line 2 Bloor–Danforth at its southwestern terminus, , and terminated in the northeast at . Until its closure in July 2023, the system had a ridership of per year. The rolling stock of Line 3 consisted of smaller, semi-automated, medium-capacity trains, rather than the larger heavy-rail subway trains used on other lines in the system. Designated by the Toronto Transit Commission (TTC) as the S series, these were Intermediate Capacity Transit System (ICTS) Mark I trains built by the Urban Transportation Development Corporation (UTDC). The trains were powered by linear induction motors and operated on tracks, unlike th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crown Corporations Of Canada
Crown corporation () is the term used in Canada for organizations that are structured like private companies, but are directly and wholly owned by the government. Crown corporations have a long-standing presence in the country, and have a significant economic impact, with commercial operations equivalent to 7% of Canadian GDP. Crown corporations are created to advance government policy objectives. Often they provide services to the public that are not economically viable for a private enterprise, or that do not fit exactly within the scope of any ministry. They represent a form of state-owned enterprise. Crown corporations are established by an Act of Parliament, act of parliament or an act of a provincial legislature. Federal government Crowns report to the relevant Minister of the Crown, minister in Cabinet of Canada, Cabinet, though they are "shielded from constant government intervention and legislative oversight" and thus "generally enjoy greater freedom from direct pol ...

Linear Induction Motor
A linear induction motor (LIM) is an alternating current (AC), asynchronous linear motor that works by the same general principles as other induction motors but is typically designed to directly produce motion in a straight line. Characteristically, linear induction motors have a finite primary or secondary length, which generates end-effects, whereas a conventional induction motor is arranged in an endless loop. Despite their name, not all linear induction motors produce linear motion; some linear induction motors are employed for generating rotations of large diameters where the use of a continuous primary would be very expensive. As with rotary motors, linear motors frequently run on a three-phase power supply and can support very high speeds. However, there are end-effects that reduce the motor's force, and it is often not possible to fit a gearbox to trade off force and speed. Linear induction motors are thus frequently less energy efficient than normal rotary motors for an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Third Rail
A third rail, also known as a live rail, electric rail or conductor rail, is a method of providing electric power to a railway locomotive or train, through a semi-continuous rigid conductor placed alongside or between the rails of a track (rail transport), railway track. It is used typically in a mass transit or rapid transit system, which has alignments in its own corridors, fully or almost fully segregated from the outside environment. Third-rail systems are usually supplied with direct current. Modern tram systems with street running avoid the electrical injury risk of the exposed electric rail by implementing a segmented ground-level power supply, where each segment is electrified only while covered by a vehicle which is using its power. The third-rail system of electrification is not related to the third rail used in dual gauge, dual-gauge railways. The system is generally associated with a low voltage (rarely above 750 V) and is far less used for main lines than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rapid Transit
Rapid transit or mass rapid transit (MRT) or heavy rail, commonly referred to as metro, is a type of high-capacity public transport that is generally built in urban areas. A grade separation, grade separated rapid transit line below ground surface through a tunnel can be regionally called a subway, tube, metro or underground. They are sometimes grade-separated on elevated railways, in which case some are referred to as el trains – short for "elevated" – or skytrains. Rapid transit systems are usually electric railway, electric railways, that unlike buses or trams operate on an exclusive right-of-way (transportation), right-of-way, which cannot be accessed by pedestrians or other vehicles. Modern services on rapid transit systems are provided on designated lines between metro station, stations typically using electric multiple units on railway tracks. Some systems use rubber-tyred metro, guided rubber tires, magnetic levitation (''maglev''), or monorail. The stations typica ...

Automated Guideway Transit
An automated guideway transit (AGT) or automated fixed-guideway transit or automatic guideway transit system is a type of fixed guideway transit infrastructure with a riding or suspension track that supports and physically guides one or more driverless vehicles along its length. The vehicles are often rubber tired or steel wheeled, but other traction systems including air cushion, suspended monorail and maglev have been implemented. The guideway provides both physical support, like a road, as well as the guidance. An automated line can be cheaper to run than a conventional line, due to the shorter trains and stations. AGT covers a wide variety of systems, from limited people mover systems commonly found at airports, to more complex automated train systems like the Vancouver SkyTrain. In the people mover role the term "automated people mover" (APM) is sometimes used, although this distinction is relatively rare because most people movers are automated. Larger systems span a va ...

Linear Motor
A linear motor is an electric motor that has had its stator and rotor (electric), rotor "unrolled", thus, instead of producing a torque (rotation), it produces a linear force along its length. However, linear motors are not necessarily straight. Characteristically, a linear motor's active section has ends, whereas more conventional motors are arranged as a continuous loop. Linear motors are used by the millions in high accuracy CNC machining and in industrial robots. In 2024 this market was USD 1.8 billion. A typical mode of operation is as a Lorentz force, Lorentz-type actuator, in which the applied force is linear equation, linearly proportional to the electric current, current and the magnetic field (\vec F = I \vec L \times \vec B). Many designs have been put forward for linear motors, falling into two major categories, low-acceleration and high-acceleration linear motors. Low-acceleration linear motors are suitable for maglev trains and other ground-based transportation ap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Railway Electrification System
Railway electrification is the use of electric power for the propulsion of rail transport. Electric railways use either electric locomotives (hauling passengers or freight in separate cars), electric multiple units ( passenger cars with their own motors) or both. Electricity is typically generated in large and relatively efficient generating stations, transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and transmission lines, but most purchase power from an electric utility. The railway usually provides its own distribution lines, switches, and transformers. Power is supplied to moving trains with a (nearly) continuous conductor running along the track that usually takes one of two forms: an overhead line, suspended from poles or towers along the track or from structure or tunnel ceilings and contacted by a pantograph, or a third rail mounted at track level and contacted by a sliding " pickup ...
