CTA 5000 Series (1947)
The 5000 series is a series of Chicago "L" car built between 2009 and 2015 by Bombardier Transportation of Plattsburgh, New York. A $577 million order for 406 cars was placed in 2006. In July 2011, the CTA ordered 300 more cars (later increased to 308 cars) for $331 million as an option on the first contract. The 5000-series reuses a numbering set used on 4 experimental articulated train-sets that were in service from 1947 to 1985. These are the first CTA railcars to have interior LED signs that display date and time. Specifications The first 10 cars began testing in passenger service on April 19, 2010. Following completion of the testing phase and acceptance of the rail cars, a dozen cars are expected to be delivered every month until all cars are in service. Seating is longitudinal, with passengers facing a wider aisle. This has increased capacity by 20–30% to a total of 123. Vertical stanchions and horizontal overhead bars with straps have been added throughout much of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chicago "L" Rolling Stock
The current rolling stock of the Chicago "L" rapid transit system consists of 4 series of railcars. The oldest series is the 2600-series which was built between 1981 and 1987 and refurbished between 1999 and 2002. The second series is the 3200-series, built between 1992 and 1994 and refurbished between 2015 and 2018. The third and newest series is known as the 5000-series; built between 2009 and 2015, they feature new technologies such as LED color signs, security cameras, new seating configuration, AC motors, and interior LED signs displaying date and time. The most recent order consists of the 7000-series cars that are planned to replace the 2600-series cars, with options for additional cars that would replace the 3200-series cars. All cars are tall (from top of rail) and long (over coupler pulling faces). They are wide at the window sills but only wide at the door sills. Currently, most railcars operating on the Chicago "L" are DC power only; the 5000-series and 7000-seri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Induction Motor
An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor. An induction motor's rotor can be either wound type or squirrel-cage type. Three-phase squirrel-cage induction motors are widely used as industrial drives because they are self-starting, reliable and economical. Single-phase induction motors are used extensively for smaller loads, such as household appliances like fans. Although traditionally used in fixed-speed service, induction motors are increasingly being used with variable-frequency drives (VFD) in variable-speed service. VFDs offer especially important energy savings opportunities for existing and prospective induction motors in variable-torque centrifugal fan, pump and compressor load applications. Squirrel ...

Yellow Line (CTA)
The Yellow Line, alternatively known as the Skokie Swift, is a branch of the Chicago "L" in Chicago, Illinois. The route runs from the Howard Terminal on the north side of Chicago, through the southern part of Evanston and to the Dempster Terminal in Skokie, Illinois making one intermediate stop at Oakton Street in Skokie. At Howard, Yellow Line passengers can transfer to the Purple or Red Lines of the "L". The Yellow Line is the only "L" line that does not go to The Loop and is the only "L" train route that is fully ADA accessible. It is also unique in that it runs in a below-grade trench for part of its length, even though it has no underground portions and does not run in an expressway median. It also includes grade segments and crossings at the northern portion of the line. It was built using the tracks of the former Chicago North Shore and Milwaukee Railroad's high-speed Skokie Valley Route. Extending the line to Old Orchard Mall in Skokie has been discussed. At one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Green Line (CTA)
The Green Line is a rapid transit line on the Chicago Transit Authority's "L" system. It is a completely elevated route in the "L" system; all other routes may have various combinations of elevated, subway, street level (at grade), or freeway median sections. The Green Line utilizes the system's oldest segments, dating back to 1892, extending with 30 stops between Oak Park/Forest Park (Harlem/Lake) and Chicago's West Side, to the Loop, and then to the South Side neighborhoods of West Englewood (Ashland/63rd) and Woodlawn (Cottage Grove/63rd). As of 2021, approximately 15,000 passengers board this line each weekday. Route Lake Street Elevated Beginning at the yard and inspection facilities in Forest Park, the Green Line runs east through Oak Park towards the city on an embankment adjacent to Metra's Union Pacific/West Line tracks from the Harlem Avenue terminal, on the border of Oak Park and Forest Park, to a point just west of Laramie Avenue.

Pink Line (CTA)
The Pink Line is an rapid transit line in Chicago, run by the Chicago Transit Authority (CTA) as part of the Chicago "L" system. It is the CTA's newest rail line and began operation for a 180-day trial period on June 25, 2006, running between 54th/Cermak station in Cicero, Illinois and the Loop in downtown Chicago. The route, as the line is about to enter downtown Chicago, shares tracks with Green Line trains on Lake Street. This connection is handled by the previously non-revenue Paulina Connector set of tracks. In 2021, an average of 7,779 passengers boarded Pink Line trains on weekdays. Operation On the Pink Line, what was once the Blue Line's Cermak branch, begins at 54th Avenue and Cermak Road in Cicero (5400 W. - 2200 S.). The line runs on at-grade tracks parallel to Cermak Road from the terminal to about a quarter-mile (400 m) east of Cicero Avenue, then diagonals northeast until it reaches a corridor parallel and adjacent to 21st Street at Kostner Avenue.

Multiple-unit Train Control
Multiple-unit train control, sometimes abbreviated to multiple-unit or MU, is a method of simultaneously controlling all the traction equipment in a train from a single location—whether it is a multiple unit comprising a number of self-powered passenger cars or a set of locomotives—with only a control signal transmitted to each unit. This contrasts with arrangements where electric motors in different units are connected directly to the power supply switched by a single control mechanism, thus requiring the full traction power to be transmitted through the train. A set of vehicles under multiple unit control is referred to as a consist in the United States. Origins Multiple unit train control was first used in electric multiple units in the 1890s. The Liverpool Overhead Railway The Liverpool Overhead Railway opened in 1893 with two-car electric multiple units, controllers in cabs at both ends directly controlling the traction current to motors on both cars.

3200 Series (Chicago "L")
The 3200-series (numbered 3201–3457) is a series of 'L' cars built between 1992 and 1994 by Morrison-Knudsen of Hornell, New York, with body shells built by Brazilian subcontractor Mafersa.Bushell, Chris (Ed.) (1991). ''Jane's Urban Transport Systems 1991'', p. 409. Coulsdon, Surrey (UK): Jane's Information Group. . A total of 257 cars were built, of which 255 remain in service. The 3200-series was the last of five series of Chicago "L" cars known as the High Performance Family and the last railcars ordered for the Chicago Transit Authority that use direct current motors. Future train orders are using alternating current motors. The original order for 256 cars was used for the opening of the Orange Line, which needed new cars when it opened in October 1993. The order was completed in 1994. The 3200-series contains many innovations over the previous 2600-series, including solid state computerized (microprocessor) control for much of the cab functions and traction system. ...

2600 Series (Chicago "L")
The 2600-series is a series of Chicago "L" car built between 1981 and 1987 by the Budd Company of Philadelphia, Pennsylvania. 600 cars were built, and 507 of them remain in service. History The 2600-series cars (numbered 2601–3200) were manufactured by the Budd Company, the same company that made the 2200-series. The fourth of five series of Chicago "L" cars known as the High Performance Family, they are quite similar in design to the earlier 2400-series cars. The cars were first delivered to the CTA in 1981, in time for the upcoming O'Hare Airport extension of the Kennedy Line (now known as the northwestern end of the Blue Line). Originally, an order was made for 300 cars, but this order was later increased to 600 cars, all of which were delivered from 1981 until 1987. They were the last railcars to be built by the Budd Company, later renamed to Transit America. The cars were rebuilt by Alstom of Hornell, New York, from 1999 until 2002. Currently, these cars make up most o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Track Brake
A magnetic track brake (Mg brake) is a brake for rail vehicles. It consists of brake magnets, pole shoes, a suspension, a power transmission and, in the case of mainline railroads, a track rod. When current flows through the magnet coil, the magnet is attracted to the rail, which presses the pole shoes against the rail, thereby decelerating the vehicle. While brakes such as disc brakes or shoe brakes depend on the frictional connection between wheel and rail, the magnetic track brake acts directly on the rail. Therefore, its brake effect is not limited by wheel-rail contact. Thus, environmental factors such as wetness or contamination of the rail have less influence on the brake force. Usage Magnetic track brakes are used on rail vehicles in addition to the primary, wheel-effective brake systems. As an additional brake system, they help to ensure that the prescribed brake distances of rail vehicles can be complied with. Since magnetic track brakes always act unregulated and ...
