Charlestown Elevated
The Charlestown Elevated was a segment of the MBTA Orange Line rapid transit line that ran from the Canal Street Incline in downtown Boston, Massachusetts through Charlestown to a terminal in Everett, Massachusetts. It opened in June 1901 and was replaced by the Haymarket North Extension in April 1975. Route The Charlestown Elevated began at the Canal Street Incline, just north of Haymarket Square in the Bulfinch Triangle section of downtown Boston, Massachusetts. It paralleled the Causeway Street Elevated north to North Station just south of Boston Garden. There it turned east along Causeway Street to Tower C, the split with the Atlantic Avenue Elevated, then north over the Charlestown Bridge. The Elevated turned slightly with an elevated station at City Square, then followed Main Street through Charlestown with a station at Thompson Square. Sullivan Square, the original terminal, was a grand arched brick building with multiple streetcar loops. The Sullivan Square Shops, ...

MBTA Orange Line
The Orange 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 on the surface from Oak Grove station in Malden, Massachusetts through Malden and Medford, paralleling the Haverhill Line, then crosses the Mystic River on a bridge into Somerville, then into Charlestown. It passes under the Charles River and runs through Downtown Boston in the Washington Street Tunnel. The line returns to the surface in the South End, then follows the Southwest Corridor southwest in a cut through Roxbury and Jamaica Plain to Forest Hills station. The Orange Line operates during normal MBTA service hours (all times except late nights) with six-car trains. A 120-car fleet built in 1979–1981 is being replaced with a 152-car CRRC fleet from 2018 to 2023. The Orange Line is fully grade-separated; trains are driven by operators with automatic train control for safety. Wellington Carhouse in Medford is ...

Thompson Square (MBTA Station)
Thompson Square was a rapid transit station in Charlestown, Massachusetts. It served the Charlestown Elevated, part of the MBTA's Orange Line, from 1902 until 1975. History Thompson Square station opened on May 22, 1902, almost a year after the rest of the Charlestown Elevated line, as an infill station. It was closed in 1975, when the line was rerouted into a tunnel that was constructed as part of the Haymarket North Extension The Haymarket North Extension is a section of the Massachusetts Bay Transportation Authority's rapid transit Orange Line which currently constitutes the northern section of the line.

Corrosion
Corrosion is a natural process that converts a refined metal into a more chemically stable oxide. It is the gradual deterioration of materials (usually a metal) by chemical or electrochemical reaction with their environment. Corrosion engineering is the field dedicated to controlling and preventing corrosion. In the most common use of the word, this means electrochemical oxidation of metal in reaction with an oxidant such as oxygen, hydrogen or hydroxide. Rusting, the formation of iron oxides, is a well-known example of electrochemical corrosion. This type of damage typically produces oxide(s) or salt(s) of the original metal and results in a distinctive orange colouration. Corrosion can also occur in materials other than metals, such as ceramics or polymers, although in this context, the term "degradation" is more common. Corrosion degrades the useful properties of materials and structures including strength, appearance and permeability to liquids and gases. Many structural ...

Tidal Estuary
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment. The mixing of seawater and freshwater provides high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns. They can have many different names, such as bays, harb ...

Boston Harbor
Boston Harbor is a natural harbor and estuary of Massachusetts Bay, and is located adjacent to the city of Boston, Massachusetts. It is home to the Port of Boston, a major shipping facility in the northeastern United States. History Since its discovery to Europeans by John Smith in 1614, Boston Harbor has been an important port in American history. Early on, it was recognized by Europeans as one of the finest natural harbors in the world due to its depth and natural defense from the Atlantic as a result of the many islands that dot the harbor. It was also favored due to its access to the Charles River, Neponset River and Mystic River which made travel from the harbor deeper into Massachusetts far easier. It was the site of the Boston Tea Party, as well as almost continuous building of wharves, piers, and new filled land into the harbor until the 19th century. By 1660, almost all imports came to the greater Boston area and the New England coast through the waters of Boston ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Washington Street Elevated
The Washington Street Elevated was an elevated segment of Boston's Massachusetts Bay Transportation Authority subway system, comprising the southern stretch of the Orange Line.

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Malden, Massachusetts
Malden is a city in Middlesex County, Massachusetts, United States. At the time of the 2020 U.S. Census, the population was 66,263 people. History Malden, a hilly woodland area north of the Mystic River, was settled by Puritans in 1640 on land purchased in 1629 from the Pennacook tribe and a further grant in 1639 by the Squaw Sachem of Mistick and her husband, Webcowet. The area was originally called the "Mistick Side" and was a part of Charlestown. It was incorporated as a separate town in 1649 under the name "Mauldon". The name Malden was selected by Joseph Hills, an early settler and landholder, and was named after Maldon, England. The city originally included what are now the adjacent cities of Melrose (until 1850) and Everett (until 1870). At the time of the American Revolution, the population was at about 1,000 people, and the citizens were involved early in resisting British rule: they boycotted the consumption of tea in 1770 to protest the Revenue Act of 1766, and ...

Boston Elevated Railway
The Boston Elevated Railway (BERy) was a streetcar and rapid transit railroad operated on, above, and below, the streets of Boston, Massachusetts and surrounding communities. Founded in 1894, it eventually acquired the West End Street Railway via lease and merger to become the city's primary mass transit provider. Its modern successor is the state-run Massachusetts Bay Transportation Authority (MBTA), which continues to operate in part on infrastructure developed by BERy and its predecessors. History Originally intended to build a short electric trolley line to Brookline, the West End Street Railway was organized in 1887. By the next year it had consolidated ownership of a number of horse-drawn streetcar lines, composing a fleet of 7,816 horses and 1,480 rail vehicles. As the system grew, a switch to underground pulled-cable propulsion (modeled after the San Francisco cable cars) was contemplated. After visiting Frank Sprague and witnessing the Richmond, Virginia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infill Station
An infill station (sometimes in-fill station) is a train station built on an existing passenger rail, rapid transit, or light rail line to address demand in a location between existing stations. Such stations take advantage of existing train service and encourage new riders by providing a more convenient location. Many older transit systems have widely spaced stations and can benefit from infill stations. In some cases, new infill station are built at sites where a station had once existed many years ago, for example the station on the Chicago 'L''s Green Line.
