R44 (New York City Subway Car)
The R44 is a New York City Subway car model built by the St. Louis Car Company from 1971 to 1973 for the B Division (New York City Subway), B Division and the Staten Island Railway (SIR). The cars replaced many R1–9 fleet, R1–9 series cars, and all remaining ME-1 (New York City Subway car), 1925 Standard Steel built SIRTOA ME-1 trains, providing Staten Island with a new fleet of railcars. The R44 fleet initially consisted of 352 cars; the remaining ones operate on the Staten Island Railway. The first R44 cars entered service on the subway on April 19, 1972, and on the Staten Island Railway on February 28, 1973. Various modifications were made over the years to the R44 fleet. The R44s set the Land speed record for railed vehicles, world speed record for a subway car in 1972, reaching a top speed of . In the early 1990s, the R44 cars were rebuilt by Morrison–Knudsen for the New York City Transit Authority. Though the R160 (New York City Subway car), R160 order replaced all Ne ...

Staten Island Railway
The Staten Island Railway (SIR) is a rapid transit, railroad line in the New York City borough (New York City), borough of Staten Island. It is owned by the Staten Island Rapid Transit Operating Authority (SIRTOA), a subsidiary of the Metropolitan Transportation Authority, and operated by the New York City Transit Authority Department of Subways. SIR operates 24 hours a day, seven days a week, providing local service between St. George Terminal, St. George and Tottenville station, Tottenville, along the east side of the island. There is currently only one line on the island, and there is no direct rail link between the SIR and the New York City Subway system, but SIR riders do receive a free Transfer (public transit), transfer to New York City Transit bus and subway lines, and the line is included on official New York City Subway maps. Commuters on the railway typically use the Staten Island Ferry to reach Manhattan. The line is accessible from within the Ferry Terminal, and mo ...

Dynamic Braking
Dynamic braking is the use of an electric traction motor as a generator when slowing a vehicle such as an electric or diesel-electric locomotive. It is termed " rheostatic" if the generated electrical power is dissipated as heat in brake grid resistors, and " regenerative" if the power is returned to the supply line. Dynamic braking reduces wear on friction-based braking components, and regeneration lowers net energy consumption. Dynamic braking may also be used on railcars with multiple units, light rail vehicles, electric trams, trolleybuses, and electric and hybrid electric automobiles. Principle of operation Converting electrical energy to the mechanical energy of a rotating shaft (electric motor) is the inverse of converting the mechanical energy of a rotating shaft to electrical energy (electric generator). Both are accomplished through the interactions of armature windings with a (relatively) moving external magnetic field, with the armature connected to an electrical ...

Railway Age
''Railway Age'' is an American trade magazine for the rail transport industry. It was founded in 1856 in Chicago (the United States' major railroad hub) and is published monthly by Simmons-Boardman Publishing Corporation. History The magazine's original title was the ''Western Railroad Gazette,'' and it was renamed the '' Railroad Gazette'' in 1870. In June 1908, after purchasing its chief rival, ''The Railway Age'' (founded in 1876 in Chicago), it changed its title to ''Railroad Age Gazette'', then in January 1910, to ''Railway Age Gazette''. In 1918, it shortened its name to the current title. ''Railway Review'' (originally the ''Chicago Railway Review'') was merged into ''Railway Age'' in 1927. Publications that have been merged into ''Railway Age'' include ''American Railroad Journal'', founded in 1832, renamed ''The Railroad and Engineering Journal'' in 1887 by its then-new owner/editor, Matthias N. Forney. It became ''American Engineer & Railroad Journal'' in 1883, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
R32 (New York City Subway Car)
The R32 was a New York City Subway car model built by the Budd Company from 1964 to 1965 for the Independent Subway System, IND/Brooklyn–Manhattan Transit Corporation, BMT B Division (New York City Subway), B Division. A total of 600 R32s were built, numbered 3350–3949, though some cars were re-numbered. The R32 contract was divided into two subcontracts of 300 cars each: R32 (cars 3350–3649) and R32A (cars 3650–3949); the former was paid by the city's capital budget and the latter was paid through a revenue bond. All were arranged as married pairs. The R32s were the first mass-produced stainless steel cars built for the New York City Subway. A ceremonial introduction trip for the new R32 "Brightliners" cars was held on September 9, 1964. Various modifications were made over the years to the R32 fleet. In the late 1980s, all of the R32 cars were rebuilt, with ten cars being rebuilt by General Electric and the remaining cars being rebuilt by Morrison–Knudsen. As part of ...

Staten Island
Staten Island ( ) is the southernmost of the boroughs of New York City, five boroughs of New York City, coextensive with Richmond County and situated at the southernmost point of New York (state), New York. The borough is separated from the adjacent state of New Jersey by the Arthur Kill and the Kill Van Kull and from the rest of New York by New York Bay. With a population of 495,747 in the 2020 United States census, 2020 Census, Staten Island is the least populated New York City borough but the third largest in land area at ; it is also the least densely populated and most suburban borough in the city. A home to the Lenape Native Americans, the island was settled by Dutch colonists in the 17th century. It was one of the 12 original counties of New York state. Staten Island was City of Greater New York, consolidated with New York City in 1898. It was formerly known as the Borough of Richmond until 1975, when its name was changed to Borough of Staten Island. Staten Island has so ...

Halogen Light Bulb
A halogen lamp (also called tungsten halogen, quartz-halogen, and quartz iodine lamp) is an incandescent lamp consisting of a tungsten filament sealed in a compact transparent envelope that is filled with a mixture of an inert gas and a small amount of a halogen, such as iodine or bromine. The combination of the halogen gas and the tungsten filament produces a halogen-cycle chemical reaction, which redeposits evaporated tungsten on the filament, increasing its life and maintaining the clarity of the envelope. This allows the filament to operate at a higher temperature than a standard incandescent lamp of similar power and operating life; this also produces light with higher luminous efficacy and color temperature. The small size of halogen lamps permits their use in compact optical systems for projectors and illumination. The small glass envelope may be enclosed in a much larger outer glass bulb, which has a lower temperature, protects the inner bulb from contamination, and ma ...

Train Stop
Part of a railway signalling system, a train stop, trip stop or tripcock (sometimes called a tripper) is a train protection device that automatically stops a train if it attempts to pass a signal when the signal aspect and operating rules prohibit such movement, or (in some applications) if it attempts to pass at an excessive speed. Basic operation The train stop system comprises two basic components. One is the trip arm mechanism, mounted on the ground adjacent to the rail, which essentially consists of a spring-loaded arm connected to an electric motor (or pneumatic cylinder in electro-pneumatic systems). The other is the train-mounted trip cock, which is connected either directly or electrically to the train's braking system. The trip arm is raised automatically whenever a train should be brought to a halt. When the signalling system determines it is safe for the train to proceed, the motor drives the trip arm down to the lowered position. The spring ensures that th ...

Pulse Code Cab Signaling
Pulse code cab signaling is a form of cab signaling technology developed in the United States by the Union Switch and Signal corporation for the Pennsylvania Railroad in the 1920s. The 4-aspect system widely adopted by the PRR and its successor railroads has become the dominant railroad cab signaling system in North America with versions of the technology also being adopted in Europe and rapid transit systems. In its home territory on former PRR successor Conrail owned lines and on railroads operating under the NORAC Rulebook it is known simply as Cab Signaling System or CSS. History In 1922 the Interstate Commerce Commission issued a ruling requiring trains to be equipped with automatic train stop technology if they were to be operated at 80 mph or greater. The Pennsylvania Railroad decided to use this as an opportunity to implement a signaling technology that could improve both safety and operational efficiency by displaying a signal continuously in the locomotive cab. ...
