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, or the T system. 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 Ashmont–Mattapan High-Speed 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 147 stations are located underground. The five branches of the Silver Line bus rapid transit 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 com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greater Boston
Greater Boston is the metropolitan region of New England encompassing the municipality of Boston (the capital of the U.S. state of Massachusetts and the most populous city in New England) and its surrounding areas. The region forms the northern arc of the Northeast megalopolis, so Greater Boston means both a metropolitan statistical area (MSA) and a combined statistical area (CSA), which is broader. The MSA consists of most of the eastern third of Massachusetts, excluding the South Coast and Cape Cod; the CSA additionally includes the municipalities of Providence (capital of Rhode Island), Manchester (the largest city in the U.S. state of New Hampshire), Worcester (the second largest city in Massachusetts and in New England), the South Coast region, and Cape Cod. While the city of Boston covers and has 675,647 residents as of the 2020 census, the urbanization has extended well into surrounding areas and the CSA has a population of more than 8.4 million people, making it one of t ...

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. Bridge A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually someth ...s (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 contras ...

Elevated Rail
An elevated railway or elevated train (also known as an el train for short) is a rapid transit 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 broad-gauge, standard-gauge or narrow-gauge railway, light rail, monorail, or a suspension railway. Elevated railways are normally found in urban areas where there would otherwise be multiple 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. The New York We ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rapid Transit
Rapid transit or mass rapid transit (MRT), also known as heavy rail or metro, is a type of high-capacity public transport generally found in urban areas. A rapid transit system that primarily or traditionally runs below the surface may be called a subway, tube, or underground. Unlike buses or trams, rapid transit systems are railways (usually electric) that operate on an exclusive right-of-way, which cannot be accessed by pedestrians or other vehicles, and which is often grade-separated in tunnels or on elevated railways. Modern services on rapid transit systems are provided on designated lines between stations typically using electric multiple units on rail tracks, although some systems use guided rubber tires, magnetic levitation ('' maglev''), or monorail. The stations typically have high platforms, without steps inside the trains, requiring custom-made trains in order to minimize gaps between train and platform. They are typically integrated with other publi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Green Line Extension
The Green Line Extension (GLX) was a construction project to extend the Massachusetts Bay Transportation Authority (MBTA) Green Line light rail system northwest into Somerville and 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. The 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 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 and storage yard is located in the Inner Belt District. The project includes a extension of ...

National Historic Landmark
A National Historic Landmark (NHL) is a building, district, object, site, or structure that is officially recognized by the United States government for its outstanding historical significance. Only some 2,500 (~3%) of over 90,000 places listed on the country's National Register of Historic Places are recognized as National Historic Landmarks. A National Historic Landmark District may include contributing properties that are buildings, structures, sites or objects, and it may include non-contributing properties. Contributing properties may or may not also be separately listed. Creation of the program Prior to 1935, efforts to preserve cultural heritage of national importance were made by piecemeal efforts of the United States Congress. In 1935, Congress passed the Historic Sites Act, which authorized the Interior Secretary authority to formally record and organize historic properties, and to designate properties as having "national historical significance", and gave the Nati ...

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 the Budapest Metro's Line 1 in 1896), opening on September 1, 1897. It was originally built, under the supervision of 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, connecting Boylston Street to Park Street and Government Center stations. History The tunnel originally served five closely spaced stations: Boylston, Park Street, Scollay Square, Adams Square, and Haymarket, with branches to the Public Garden portal and Pleasant Street incline south of Boylston. Park Street, Scollay Square, and Haymarket stations were altered over the next two decades as transfers were added to the Cambridge–Dorchester ...

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 subway line had one stop in the basement of the Rogers Peet Building and a one-car shuttle going back and forth . 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 statio ...

Park Street Station (MBTA)
Park Street station is an MBTA subway station in Boston, Massachusetts. It is located at the intersection of Park Street and Tremont Street at the eastern edge of Boston Common in Downtown Boston. One of the two oldest stations on the "T" (the other is Boylston), Park Street is the transfer point between the Green and Red lines, as one of the quartet of "hub stations" on the MBTA subway system. Park Street is the fifth-busiest station in the MBTA network, with an average of 16,571 entries each weekday in FY2019. History Initial construction Tremont Street subway The southern section of the Tremont Street subway from the Public Garden incline through Boylston to Park Street opened on September 1, 1897, followed on October 1 by the spur to the Pleasant Street Portal. The station was built with 4 tracks serving 2 island platforms; these were connected by two loops, allowing streetcars from the south and west to reverse direction and return to the portals and surface routes ...
