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 sub ...

Flying Junction
A flying junction or flyover is a railway junction at which one or more diverging or converging tracks in a multiple-track route cross other tracks on the route by bridge to avoid conflict with other train movements. A more technical term is "grade-separated junction". A burrowing junction or dive-under occurs where the diverging line passes below the main line. The alternative to grade separation is a level junction or flat junction, where tracks cross at grade, and conflicting routes must be protected by interlocked signals. Complexity Simple flying junctions may have a single track pass over or under other tracks to avoid conflict, while complex flying junctions may have an elaborate infrastructure to allow multiple routings without trains coming into conflict, in the manner of a highway stack interchange. Flying junction without crossings Where two lines each of two tracks merge with a flying junction, they can become a four-track railway together, the tracks paired by ...

Government Center Station (MBTA)
Government Center station is an MBTA subway station in Boston, Massachusetts. It is located at the intersection of Tremont, Court and Cambridge Streets in the Government Center area. It is a transfer point between the light rail Green Line and the rapid transit Blue Line. With the Green Line platform having opened in 1898, the station is the third-oldest operating subway station (and the second-oldest of the quartet of "hub stations") in the MBTA system; only Park Street and Boylston are older. The station previously served Scollay Square before its demolition for the creation of Boston City Hall Plaza. The station was closed on March 22, 2014 for a major renovation, which included retrofitting the station for accessibility and building a new glass headhouse on City Hall Plaza. The new fully accessible station was reopened on March 21, 2016. History Scollay Square As the first horsecar lines were built in the late 1850s, the Scollay Building in Scollay Square became the ...

Boston City Hall
Boston City Hall is the seat of city government of Boston, Massachusetts. It includes the offices of the mayor of Boston and the Boston City Council. The current hall was built in 1968 to assume the functions of the Old City Hall. It is a controversial and prominent example of Brutalist architecture, part of the modernist movement. It was designed by the architecture firms Kallmann McKinnell & Knowles and Campbell, Aldrich & Nulty, with LeMessurier Consultants as engineers. Together with the surrounding plaza, City Hall is part of the Government Center complex. This project constituted a major urban redesign effort in the 1960s, as Boston demolished an area of substandard housing and businesses. The building has been subject to widespread public condemnation, and is sometimes called one of the world's ugliest buildings. Calls for the structure to be demolished have been regularly made even before construction was finished. Architects and critics considered it to be excellent ...

Government Center, Boston, Massachusetts
Government Center is an area in downtown Boston, centered on City Hall Plaza. Formerly the site of Scollay Square, it is now the location of Boston City Hall, courthouses, state and federal office buildings, and a major MBTA subway station, also called Government Center. Its development was controversial, as the project displaced thousands of residents and razed several hundred homes and businesses. Controversial in design since before it was completed, the use of Brutalist architecture for its main buildings, as well as the open brick-and-concrete plaza at the center of the development, have been alternately praised for its innovative design, and scorned for its lack of character and uninviting appearance. After decades of calls for a redesign to make it more friendly and usable, a major rebuild of City Hall Plaza, the main public space of Government Center, was begun in 2020 and is to include additional seating areas, play spaces for children, and space for public art.

Headhouse
A head house or headhouse may be an enclosed building attached to an open-sided shed, or the aboveground part of a subway station. Markets In the 18th and early 19th centuries, head houses were often civic buildings such as town halls or courthouses located at the end of an open market shed; one example is the former market and firehouse from which Philadelphia's Head House Square takes its name. Mines In mining, a headhouse is the housing of the headworks of various types of machinery used for moving coal to the surface, or men to or from it. Transportation Railroads Since the mid-19th century, in the United States, a head house has often been the part of a passenger train station that does not house the tracks and platforms. Elsewhere, the same part of a station is known as the station building. In particular, it often contains the ticket counters, waiting rooms, toilets and baggage facilities. It might also include the passenger concourses and walkways between the platfor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Blue Line (MBTA)
The Blue Line is a rapid transit line in the Greater Boston metropolitan area, one of four rapid transit lines operated by the Massachusetts Bay Transportation Authority (MBTA). It runs from Bowdoin station in downtown Boston under Boston Harbor to East Boston and Revere on the inner North Shore, where it terminates at Wonderland. The stop at Airport Station, by way of a free shuttle bus, is one of two rapid transit connections to Logan International Airport. In 1967, during a systemwide rebranding, the line was assigned the blue color because it passes under the Boston Harbor. With an end-to-end travel time of less than twenty minutes, the Blue Line is the shortest of Boston's heavy-rail lines and the only line to have both third rail and overhead catenary sections. The East Boston Tunnel was built as a streetcar tunnel in 1904 with Howard A. Carson as chief engineer; after an extension to Bowdoin in 1916, it was converted to heavy rail metro rolling stock in 1924. In 1952 a ...
