PCC Streetcar
The Presidents' Conference Committee (PCC) is a streetcar (tram) design that was first built in the United States in the 1930s. The design proved successful domestically, and after World War II it was licensed for use elsewhere in the world where PCC based cars were made. The PCC car has proved to be a long-lasting icon of streetcar design. Approximately 5,000 PCC streetcars were built in the United States, with production continuing until 1952. In North America, some PCC streetcars are still in regular service, with most operating on heritage streetcar lines. , the San Francisco Municipal Railway is the largest North American operator of PCC cars, using a fleet of 27 on two heritage lines. After World War II, the PCC design was licensed to multiple European companies. Over 15,000 PCC-derived streetcars were built in Europe, including the popular Tatra T3. Origins The Presidents' Conference Committee (PCC) originated from the design committee formed in 1929. It was renamed t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tram
A tram (also known as a streetcar or trolley in Canada and the United States) is an urban rail transit in which Rolling stock, vehicles, whether individual railcars or multiple-unit trains, run on tramway tracks on urban public streets; some include segments on segregated Right-of-way (property access), right-of-way. The tramlines or tram networks operated as public transport are called tramways or simply trams/streetcars. Because of their close similarities, trams are commonly included in the wider term ''light rail'', which also includes systems separated from other traffic. Tram vehicles are usually lighter and shorter than Main line (railway), main line and rapid transit trains. Most trams use electrical power, usually fed by a Pantograph (transport), pantograph sliding on an overhead line; older systems may use a trolley pole or a bow collector. In some cases, a contact shoe on a third rail is used. If necessary, they may have dual power systems—electricity in city stre ...

Chicago Surface Lines
The Chicago Surface Lines (CSL) was operator of the street railway system of Chicago, Illinois, Chicago, Illinois, from 1913 to 1947. The firm is a predecessor of today's publicly owned operator, the Chicago Transit Authority. History The first streetcars in Chicago were horsecar, horse cars run by the Chicago City Railway Company and the North Chicago City Railway Company around 1858-1861. This method was slow and expensive, and the companies began substituting Cable car (railway), cable cars in the 1880s. Chicago City Railway was the first in (1881), and with the addition of the Chicago Passenger Railway (1883) and the West Chicago Street Railroad Company (1887), Chicago had the largest Cable cars in Chicago, cable railway system in the world. The north and west side cable car systems were constructed by an investment syndicate under the direction of Charles Yerkes. It was also in the 1880s that electric-powered "tram, trolleys" first became practical. The Chicago companies ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of MTA Maryland
The Maryland Transit Administration was originally known as the Baltimore Metropolitan Transit Authority, then the Maryland Mass Transit Administration before it changed to its current name in October 2001. The MTA took over the operations of the old Baltimore Transit Company on April 30, 1970. Many routes of the agency's current bus lines are based on the original streetcars operated by the Baltimore Transit Company and its parent companies between the 1890s and 1960s. All of these routes were ultimately converted to rubber tire bus operations, and many were consolidated, extended into newly developed areas, or otherwise reconfigured to keep up with the ridership demands of the times. Additional routes and extensions were added in later years to serve newly developed communities and to feed into Metro and Light Rail stations. With the growth in popularity of the private automobile during the 20th century, streetcar and bus ridership declined, and the needs for public transport ...

Brooklyn & Queens Transit Corporation
The Brooklyn and Queens Transit Corporation (B&QT) was a subsidiary of the Brooklyn–Manhattan Transit Corporation that operated streetcars in Brooklyn and Queens, New York City, United States (as well as into Manhattan via the Brooklyn Bridge and Williamsburg Bridge).

Bogie
A bogie ( ) (or truck in North American English) comprises two or more Wheelset (rail transport), wheelsets (two Railroad wheel, wheels on an axle), in a frame, attached under a vehicle by a pivot. Bogies take various forms in various modes of transport. A bogie may remain normally attached (as on many railroad cars and semi-trailers) or be quickly detachable (as for a dolly (trailer), dolly in a road train or in railway bogie exchange). It may include Suspension (vehicle), suspension components within it (as most rail and trucking bogies do), or be solid and in turn be suspended (as are most bogies of continuous track, tracked vehicles). It may be mounted on a swivel, as traditionally on a railway carriage or locomotive, additionally jointed and sprung (as in the landing gear of an airliner), or held in place by other means (centreless bogies). Although ''bogie'' is the preferred spelling and first-listed variant in various dictionaries, bogey and bogy are also used. Rail ...

Hypoid
A spiral bevel gear is a bevel gear with helical teeth. The main application of this is in a vehicle differential, where the direction of drive from the drive shaft must be turned 90 degrees to drive the wheels. The helical design produces less vibration and noise than conventional straight-cut or spur-cut gear with straight teeth. A spiral bevel gear set should always be replaced in pairs i.e. both the left hand and right hand gears should be replaced together since the gears are manufactured and lapped in pairs. Handedness A right hand spiral bevel gear is one in which the outer half of a tooth is inclined in the clockwise direction from the axial plane through the midpoint of the tooth as viewed by an observer looking at the face of the gear. A left hand spiral bevel gear is one in which the outer half of a tooth is inclined in the counterclockwise direction from the axial plane through the midpoint of the tooth as viewed by an observer looking at the face of the gear. ...

Brilliner
Brilliner was a tram designed by the J. G. Brill Company. The tram was designed to be a competitor to the successful PCC cars, but the design ended up being a failure for the company, with only several trams built. The tram utilized a clean, streamlined design, similar to a PCC car. It also used a boxy floor plan and a riveted steel body design. Due to the boxy floor plan, Brilliner cars could not clear the tight spaces required by the Philadelphia Transportation Company (PTC), the company's main customer. The Brilliner was the company's last trolley design before merging with American Car and Foundry (ACF). 10 cars were built for Red Arrow Lines (these were the only double-ended variants as every other car was single-ended), 24 trams were sold to Atlantic City, 3 cars were sold to the PTC, and one of each was sold to Cincinnati and Baltimore Baltimore is the most populous city in the U.S. state of Maryland.

Streamliner
A streamliner is a vehicle incorporating streamlining in a shape providing reduced air resistance. The term is applied to high-speed railway trainsets of the 1930s to 1950s, and to their successor " bullet trains". Less commonly, the term is applied to fully faired upright and recumbent bicycles. As part of the Streamline Moderne trend, the term was applied to passenger cars, trucks, and other types of light-, medium-, or heavy-duty vehicles, but now vehicle streamlining is so prevalent that it is not an outstanding characteristic. In land speed racing, it is a term applied to the long, slender, custom built, high-speed vehicles with enclosed wheels. Trains Before World War II Europe * Germany, 1930: The first high-speed streamliner in Germany was the '' Schienenzeppelin'', an experimental propeller-driven single car, built in 1930. On 21 June 1931, the car set a speed record of on a run between Berlin and Hamburg. In 1932 the propeller was removed and a h ...
