State-of-the-Art Car
The State-of-the-Art Car (SOAC) was a heavy rail mass transit demonstrator vehicle produced for the United States Department of Transportation's Urban Mass Transportation Administration in the 1970s. It was intended to demonstrate the latest technologies to operating agencies and the riding public, and serve to promote existing and proposed transit lines. A single married pair was produced by the St. Louis Car Company in 1972. It operated in intermittent revenue service on six rapid transit systems in five United States cities between May 1974 and January 1977. Since 1989, the two cars have been on display at the Seashore Trolley Museum in Kennebunkport, Maine. Design and development Around 1970, the United States Department of Transportation's Urban Mass Transportation Administration (UMTA) began the Urban Rapid Rail Vehicle and Systems Program with the intention of creating a new rapid transit vehicle for use on existing and proposed systems. The new cars were to represent th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Married Pair
A twin unit or twinset is a set of two railroad cars or locomotives which are permanently coupled and treated as if they were a single unit. A twinset of cars or coaches can also be called a twin car. In US passenger railroad parlance, twin units are also known as married pairs. On passenger railroads, light rail, and monorail services, married pairs may have machinery necessary for full operation of the cars split between them. Items that are typically shared include transformers, motor controllers, dynamic braking grids, cabs, current collectors, batteries, and air compressors. This provides significant savings in both cost of equipment and weight, which increases performance and decreases energy consumption. The cost of operating such a pair may be slightly higher when the extra car in such a pair is not needed to meet level-of-service demands at a particular time.

Pullman-Standard
The Pullman Company, founded by George Pullman, was a manufacturer of railroad cars in the mid-to-late 19th century through the first half of the 20th century, during the boom of railroads in the United States. Through rapid late-19th century development of mass production and takeover of rivals, the company developed a virtual monopoly on production and ownership of sleeper cars. During a severe economic downturn, the 1894 Pullman Strike by company workers proved a transforming moment in American labor history. At the company's peak in the early 20th century, its cars accommodated 26 million people a year, and it in effect operated "the largest hotel in the world". Its production workers initially lived in a planned worker community (or " company town") named Pullman, Chicago. Pullman developed the sleeping car, which carried his name into the 1980s. Pullman did not just manufacture the cars, it also operated them on most of the railroads in the United States, paying r ... [...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 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 from direct current electricity. Modern tram systems, street-running, avoid the risk of electrocution by 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 railways. Description Third-rail systems are a means of providing electric traction power to trains using an additional rail (called a "conductor rail") fo ...

Skokie Swift
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.

Independent Subway System
The Independent Subway System (IND or ISS), formerly known as the Independent City-Owned Subway System (ICOSS) or the Independent City-Owned Rapid Transit Railroad (ICORTR), was a rapid transit rail system in New York City that is now part of the New York City Subway. It was first constructed as the Eighth Avenue Line in Manhattan in 1932. One of three rail networks that became part of the modern New York City subway, the IND was intended to be fully owned and operated by the municipal government, in contrast to the privately operated or jointly funded Interborough Rapid Transit Company (IRT) and Brooklyn–Manhattan Transit Corporation (BMT) companies. It was merged with these two networks in 1940. The original IND service lines are the modern subway's A, B, C, D, E, F, and G services. In addition, the BMT's M, N, Q and R now run partly on IND trackage. The Rockaway Park Shuttle supplements the A service. For operational purposes, the IND and BMT lines and service ...

Bay Area Rapid Transit Rolling Stock
The rolling stock of the Bay Area Rapid Transit (BART) system consists of 782 Self propelled rail vehicle, self-propelled electric multiple units, built from four separate orders, along with a number of automobiles used by BART police and others. To run a typical peak morning commute, BART requires 579 cars. Of those, 535 are scheduled to be in active service; the others are used to build up four spare trains (essential for maintaining on-time service). At any one time, the remaining 90 cars are in for repair, maintenance, or some type of planned modification work. All trains on the separate automated guideway transit line are in regular use without spares. Bombardier Transportation is manufacturing a complete replacement of the mainline fleet, due to be delivered in batches by Fall 2021. The first ten cars of this replacement fleet entered service in 2018, with all expected to enter service by 2022. With the withdrawal and retirement of the older fleet, there will be 775 vehicles ...
