Boston And Lowell
The Boston and Lowell Railroad was a railroad that operated in Massachusetts in the United States. It was one of the first railroads in North America and the first major one in the state. The line later operated as part of the Boston and Maine Railroad's Southern Division. Formation The Boston and Lowell Railroad was preceded by the Middlesex Canal. Converting the canal to a railroad would eliminate the issue of transportation being unavailable during the winter, when the canal froze. Patrick Tracy Jackson led the task of convincing the state legislature to fund the project. This proved difficult, as the investors of the Middlesex Canal were against building a new form of transportation designed to replace their canal. Because, prior to 1872, there was no provision in Massachusetts state law for chartering railroads, all had to be chartered by special acts of legislature. This made it slow and inefficient to charter a railroad because the politicians had to agree; the issue woul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boston
Boston (), officially the City of Boston, is the state capital and most populous city of the Commonwealth of Massachusetts, as well as the cultural and financial center of the New England region of the United States. It is the 24th- most populous city in the country. The city boundaries encompass an area of about and a population of 675,647 as of 2020. It is the seat of Suffolk County (although the county government was disbanded on July 1, 1999). The city is the economic and cultural anchor of a substantially larger metropolitan area known as Greater Boston, a metropolitan statistical area (MSA) home to a census-estimated 4.8 million people in 2016 and ranking as the tenth-largest MSA in the country. A broader combined statistical area (CSA), generally corresponding to the commuting area and including Providence, Rhode Island, is home to approximately 8.2 million people, making it the sixth most populous in the United States.

Medford, Massachusetts
Medford is a city northwest of downtown Boston on the Mystic River in Middlesex County, Massachusetts, United States. At the time of the 2020 U.S. Census, Medford's population was 59,659. It is home to Tufts University, which has its campus along the Medford and Somerville border. History Indigenous history Native Americans inhabited the area that would become Medford for thousands of years prior to European colonization of the Americas. At the time of European contact and exploration, Medford was the winter home of the Naumkeag people, who farmed corn and created fishing weirs at multiple sites along the Mystic River. Naumkeag sachem Nanepashemet was killed and buried at his fortification in present-day Medford during a war with the Tarrantines in 1619. The contact period introduced a number of European infectious diseases which would decimate native populations in virgin soil epidemics, including a smallpox epidemic which in 1633 which killed Nanepashemet's sons, sachems ...

Moveable Bridge
A moveable bridge, or movable bridge, is a bridge that moves to allow passage for boats or barges. In American English, the term is synonymous with , and the latter is the common term, but drawbridge can be limited to the narrower, historical definition used in some other forms of English, in which ''drawbridge'' refers to only a specific type of moveable bridge often found in castles . An advantage of making bridges moveable is the lower cost, due to the absence of high piers and long approaches. The principal disadvantage is that the traffic on the bridge must be halted when it is opened for passage of traffic on the waterway. For seldom-used railroad bridges over busy channels, the bridge may be left open and then closed for train passages. For small bridges, bridge movement may be enabled without the need for an engine. Some bridges are operated by the users, especially those with a boat, others by a bridgeman (or bridge tender); a few are remotely controlled using video-cam ...

Charles River
The Charles River ( Massachusett: ''Quinobequin)'' (sometimes called the River Charles or simply the Charles) is an river in eastern Massachusetts. It flows northeast from Hopkinton to Boston along a highly meandering route, that doubles back on itself several times and travels through 23 cities and towns before reaching the Atlantic Ocean. The indigenous Massachusett named it ''Quinobequin'', meaning "meandering". Hydrography The Charles River is fed by approximately 80 streams and several major aquifers as it flows , starting at Teresa Road just north of Echo Lake () in Hopkinton, passing through 23 cities and towns in eastern Massachusetts before emptying into 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 .... Thirty-three lakes and ponds and 35 munic ...

Railroad Tie
A railroad tie, crosstie (American English), railway tie (Canadian English) or railway sleeper (Australian and British English) is a rectangular support for the rails in railroad tracks. Generally laid perpendicular to the rails, ties transfer loads to the track ballast and subgrade, hold the rails upright and keep them spaced to the correct gauge. Railroad ties are traditionally made of wood, but prestressed concrete is now also widely used, especially in Europe and Asia. Steel ties are common on secondary lines in the UK; plastic composite ties are also employed, although far less than wood or concrete. As of January 2008, the approximate market share in North America for traditional and wood ties was 91.5%, the remainder being concrete, steel, azobé (red ironwood) and plastic composite. Tie spacing may depend on the type of tie, traffic loads and other requirements, for example 2640 concrete ties per mile on North American mainline railroads to 2112 timber ties per mile ...

Boston And Worcester Railroad
The Boston and Albany Railroad was a railroad connecting Boston, Massachusetts to Albany, New York, later becoming part of the New York Central Railroad system, Conrail, and CSX Transportation. The line is currently used by CSX for freight. Passenger service is provided on the line by Amtrak, as part of their ''Lake Shore Limited'' service, and by the MBTA Commuter Rail system, which owns the section east of Worcester and operates it as its Framingham/Worcester Line. History When the Erie Canal opened in 1825, New York City's advantageous water connection through the Hudson River threatened Boston's historical dominance as a trade center. Since the Berkshires made construction of a canal infeasible, Boston turned to the emerging railroad technology for a share of the freight to and from the Midwestern United States. The Boston and Worcester Railroad was chartered June 23, 1831 and construction began in August 1832. The line opened in sections: to West Newton on April 16, 18 ...

George Washington Whistler
George Washington Whistler (May 19, 1800 – April 7, 1849) was a prominent American civil engineer best known for building steam locomotives and railroads. He is credited with introducing the steam whistle to American locomotives. In 1842, Tsar Nicholas I hired him to build the Saint Petersburg–Moscow Railway, Russia's first large-scale railroad.Gasparini, D. A., K. Nizamiev, and C. Tardini. "GW Whistler and the Howe Bridges on the Nikolaev Railway, 1842–1851", American Society of Civil Engineers, ''Journal of Performance of Constructed Facilities'' 30.3 (2015): DOI link:04015046.https://dx.doi.org/10.1061/(ASCE)CF.1943-5509.0000791 One of Whistler's important influences was the introduction of the Howe truss for the Russian railroad's bridges. This inspired the renowned Russian engineer Dmitrii Ivanovich Zhuravskii (1821–1891) to perform studies and develop structural analysis techniques for Howe truss bridges. He was the father of American artist James McNeill Whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

Iron
Iron () is a chemical element with symbol Fe (from la, ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, right in front of oxygen (32.1% and 30.1%, respectively), forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. In its metallic state, iron is rare in the Earth's crust, limited mainly to deposition by meteorites. Iron ores, by contrast, are among the most abundant in the Earth's crust, although extracting usable metal from them requires kilns or furnaces capable of reaching or higher, about higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BCE and the use of iron tools and weapons began to displace copper alloys, in some regions, only around 1200 BCE. That event is considered the transition from the Bronze Age to the Iron A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Irish People
The Irish ( ga, Muintir na hÉireann or ''Na hÉireannaigh'') are an ethnic group and nation native to the island of Ireland, who share a common history and culture. There have been humans in Ireland for about 33,000 years, and it has been continually inhabited for more than 10,000 years (see Prehistoric Ireland). For most of Ireland's recorded history, the Irish have been primarily a Gaelic people (see Gaelic Ireland). From the 9th century, small numbers of Vikings settled in Ireland, becoming the Norse-Gaels. Anglo-Normans also conquered parts of Ireland in the 12th century, while England's 16th/17th century conquest and colonisation of Ireland brought many English and Lowland Scots to parts of the island, especially the north. Today, Ireland is made up of the Republic of Ireland (officially called Ireland) and Northern Ireland (a part of the United Kingdom). The people of Northern Ireland hold various national identities including British, Irish, Northern Irish or som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
