MBTA Subway
The Massachusetts Bay Transportation Authority (MBTA) operates rapid transit (heavy rail), light rail, and bus rapid transit services in the Boston metropolitan area, collectively referred to as the rapid transit, subway, the T system, or simply the T. The color-branded lines consist of three heavy rail lines ( Red, Orange, and Blue), one branched light rail system (Green), and a short light rail line (the Mattapan Line, colored as part of the Red Line). All except the Ashmont–Mattapan line operate in tunnels in the downtown area, but no route operates entirely underground, and only 31 out of the system's 153 stations are located underground. The five branches of the Silver Line bus network are also shown as part of the rapid transit system. Three branches operate underground and charge rapid transit fares; two branches operate entirely on the surface and charge lower bus fares. In , the heavy rail lines had rides, or about per weekday in , and comprised the fourth-b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Line (MBTA)
The Red Line is a rapid transit line operated by the Massachusetts Bay Transportation Authority (MBTA) as part of the MBTA subway system. The line runs south and east underground from Alewife station in North Cambridge, Massachusetts, North Cambridge through Somerville, Massachusetts, Somerville and Cambridge, Massachusetts, Cambridge, surfacing to cross the Longfellow Bridge then returning to tunnels under Downtown Boston. It continues underground through South Boston, splitting into two branches on the surface at JFK/UMass station. The Ashmont branch runs southwest through Dorchester, Boston, Dorchester to Ashmont station, where the connecting light rail Mattapan Line (shown as part of the Red Line on maps, but operated separately) continues to Mattapan station. The Braintree branch runs southeast through Quincy, Massachusetts, Quincy and Braintree, Massachusetts, Braintree to Braintree station (MBTA), Braintree station. The Red Line operates during normal MBTA service hours (al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grade-separated
In civil engineering (more specifically highway engineering), grade separation is a method of aligning a junction of two or more surface transport axes at different heights ( grades) so that they will not disrupt the traffic flow on other transit routes when they cross each other. The composition of such transport axes does not have to be uniform; it can consist of a mixture of roads, footpaths, railways, canals, or airport runways. Bridges (or overpasses, also called flyovers), tunnels (or underpasses), or a combination of both can be built at a junction to achieve the needed grade separation. In North America, a grade-separated junction may be referred to as a ''grade separation'' or as an '' interchange'' – in contrast with an ''intersection'', '' at-grade'', a '' diamond crossing'' or a ''level crossing'', which are not grade-separated. Effects Advantages Roads with grade separation generally allow traffic to move freely, with fewer interruptions, and at higher over ...

Elevated Rail
An elevated railway or elevated train (also known as an el train or el for short) is a railway with the tracks above street level on a viaduct or other elevated structure (usually constructed from steel, cast iron, concrete, or bricks). The railway may be a broad-gauge, standard-gauge or narrow-gauge railway, light rail, monorail, or a suspension railway. Elevated railways are normally found in urban areas that would otherwise require impracticably many level crossings. Usually, the tracks of elevated railways that run on steel viaducts can be seen from street level. History The earliest elevated railway was the London and Greenwich Railway on a brick viaduct of 878 arches, built between 1836 and 1838. The first of the London and Blackwall Railway (1840) was also built on a viaduct. During the 1840s there were other plans for elevated railways in London that never came to fruition. From the late 1860s onward, elevated railways became popular in US cities. New York's W ... [...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 ...

Green Line Extension
The Green Line Extension (GLX) was a construction project to extend the Massachusetts Bay Transportation Authority (MBTA) Green Line (MBTA), Green Line light rail system northwest into Somerville, Massachusetts, Somerville and Medford, Massachusetts, Medford, two inner suburbs of Boston, Massachusetts. The project opened in two phases in 2022 at a total cost of $2.28 billion. Total ridership on the extension is estimated to reach 45,000 one-way trips per day in 2030. The project begins at the north end of the Lechmere Viaduct, where the former ground-level Lechmere station was replaced by an elevated station on an extended viaduct. Two branches split north of Lechmere, with the Union Square Branch following the MBTA Commuter Rail Fitchburg Line right of way to Union Square station (Somerville), Union Square station in Somerville. The Medford Branch follows the Lowell Line right-of-way to Medford/Tufts station with four intermediate stations. A new vehicle maintenance facility ...

National Historic Landmark
A National Historic Landmark (NHL) is a National Register of Historic Places property types, building, district, object, site, or structure that is officially recognized by the Federal government of the United States, United States government for its outstanding historical significance. Only some 2,500, or roughly three percent, of over 90,000 places listed on the country's National Register of Historic Places (NRHP) are recognized as National Historic Landmarks. A National Historic Landmark District may include many contributing properties that are buildings, structures, sites or objects, and it may also include non-contributing properties. Contributing properties may or may not also be separately listed as NHLs or on the NRHP. History The origins of the first National Historic Landmark was a simple cedar post, placed by the Lewis and Clark Expedition on their 1804 outbound trek to the Pacific Ocean in commemoration of the death from natural causes of Sergeant Charles Floyd (e ...

Tremont Street Subway
The Tremont Street subway in Boston's MBTA subway system is the oldest subway tunnel in North America and the third-oldest still in use worldwide to exclusively use electric traction (after the City and South London Railway in 1890, and Line 1 (Budapest Metro), the Budapest Metro's Line 1 in 1896), opening on September 1, 1897. It was originally built, under the supervision of Howard Adams Carson, Howard A. Carson as chief engineer, to get streetcar lines off the traffic-clogged streets, instead of as a true rapid transit line. It now forms the central part of the Green Line (MBTA), Green Line, connecting Boylston (MBTA station), Boylston Street to Park Street station (MBTA), Park Street and Government Center (MBTA station), Government Center stations. History The tunnel originally served five closely spaced stations: Boylston station, Boylston, Park Street, Government Center station (MBTA), Scollay Square, Adams Square station, Adams Square, and Haymarket station (MBTA), Ha ...

Beach Pneumatic Transit
The Beach Pneumatic Transit was the first attempt to build an underground public transit system in New York City. It was developed by Alfred Ely Beach in 1869 as a demonstration subway line running on pneumatic power. The line had one stop in the basement of the Rogers Peet Building, near the old City Hall station, and a one-car shuttle running between the building and a dead end approximately away. It was not a regular mode of transportation and lasted from 1870 until 1873. History Alfred Ely Beach demonstrated a model of basic pneumatic subway system, in which air pressure in the tube pushed the cars, at the American Institute Exhibition in New York in 1867. After demonstrating that the model was viable, in 1869 Beach and his Beach Pneumatic Transit Company began constructing a pneumatically powered subway line beneath Broadway. Funneled through a company he set up, Beach put up $350,000 of his own money to pay for the full-scale test project. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boylston (MBTA Station)
Boylston station (also signed as Boylston Street) is a light rail station on the MBTA Green Line in downtown Boston, Massachusetts, located on the southeast corner of Boston Common at the intersection of Boylston Street and Tremont Street. A southbound street-level stop for the route of the bus rapid transit Silver Line is outside fare control. The station has two island platforms; each has one disused track, making them effectively side platforms. Boylston is not accessible for Green Line trains. Boylston station was opened in 1897 as part of the original segment of the Tremont Street subway. Originally used by streetcars, from 1901 to 1908 it also served Main Line Elevated trains. Unlike other Green Line stations, Boylston has been little modified, and retains much of its original appearance. Two of the original four headhouses have been removed, however, and a sub-passage connecting the platforms has been sealed. Construction of a proposed underground Silver Line stat ...
