Rock Creek Railway
The Rock Creek Railway was one of the first electric streetcar companies in Washington, D.C., and the first to extend into Maryland. It was incorporated in 1888, started operations in 1890, and by 1892 ran some five miles from the Cardoza/Shaw neighborhood of D.C. to Chevy Chase Lake, Maryland. On September 21, 1895, Rock Creek Railway purchased the Washington and Georgetown Railroad Company and the two formed the Capital Traction Company. History The Rock Creek Railway was founded by Francis Newlands as part of a plan to develop streetcar suburbs in northwestern D.C. and adjacent Maryland. He and his partners incorporated the company on June 23, 1888, four days after the Eckington and Soldiers' Home Electric Railway. In 1890, service began on Florida Avenue between Connecticut Avenue NW and 18th Street NW. The company built an iron bridge across Rock Creek at Cincinnati Street NW (now Calvert Street NW), which was completed on July 21, 1891. On September 16, 1892, the line w ...

Baltimore And Ohio Railroad
The Baltimore and Ohio Railroad was the first common carrier railroad and the oldest railroad in the United States, with its first section opening in 1830. Merchants from Baltimore, which had benefited to some extent from the construction of the National Road early in the century, wanted to do business with settlers crossing the Appalachian Mountains. The railroad faced competition from several existing and proposed enterprises, including the Albany-Schenectady Turnpike, built in 1797, the Erie Canal, which opened in 1825, and the Chesapeake and Ohio Canal. At first, the B&O was located entirely in the state of Maryland; its original line extending from the port of Baltimore west to Sandy Hook, Maryland, opened in 1834. There it connected with Harper's Ferry, first by boat, then by the Wager Bridge, across the Potomac River into Virginia, and also with the navigable Shenandoah River. Because of competition with the C&O Canal for trade with coal fields in western Maryland, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Street Railways In Washington, D
A street is a public thoroughfare in a built environment. It is a public parcel of landform, land adjoining buildings in an urban area, urban context, on which people may freely assemble, interact, and move about. A street can be as simple as a level patch of soil, dirt, but is more often pavement (material), paved with a hard, durable surface such as Tarmacadam, tarmac, concrete, cobblestone or brick. Portions may also be smoothed with asphalt, embedded with track (rail transport), rails, or otherwise prepared to accommodate non-pedestrian traffic. Originally, the word ''street'' simply meant a paved road ( la, via strata). The word ''street'' is still sometimes used informally as a synonym for ''road'', for example in connection with the ancient Watling Street, but city residents and urban planning, urban planners draw a crucial modern distinction: a road's main function is transportation, while streets facilitate public interaction.

Export Control Act
The Export Control Act of 1940 was one in a series of legislative efforts by the US government and initially the administration of President Franklin D. Roosevelt to accomplish two tasks: to avoid scarcity of critical commodities in a likely prewar environment and to limit the exportation of materiel to Imperial Japan. The act originated as a presidential proclamation by Roosevelt forbidding the exporting of aircraft parts, chemicals, and minerals without a license, and it was intended to induce Japan to curtail its occupation of the coast of Indochina. The text stated that whenever the President deemed it "necessary in the interest of national defense," he could prohibit or curtail the exportation of military equipment, munitions, tools, and materials. Although controls were first authorized in 1940 in regard to munitions and similar materials essential to the defense effort, its coverage was extended in 1942 to all commodities and broader geographic coverage after the Unite ...

Conduit Electrification
Conduit current collection is an obsolete system of electric current collection used by some electric tramways, where the power supply was carried in a 'conduit' (a small tunnel) under the roadway. Modern systems fall under the term ground-level power supply. Description The power rails are contained in a conduit midway between and below the two surface rails on which the cars operate, in much the same fashion as the cable for cable cars. The conduit contains two "T" section steel power rails of opposite polarity facing each other, about apart and about below the street surface. Power reached the car by means of an attachment, called a plough (US plow), that rode in the conduit beneath the car. The plough had two metal shoes attached to springs that pushed sideways against the power rails. The plough was normally connected to a platform that could slide laterally to conform with variations in the placement of the conduit, for example in some areas there was a conduit for cable ...

Downtown Washington, D
''Downtown'' is a term primarily used in North America by English speakers to refer to a city's sometimes commercial, cultural and often the historical, political and geographic heart. It is often synonymous with its central business district (CBD). Downtowns typically contain a small percentage of a city’s employment. In some metropolitan areas it is marked by a cluster of tall buildings, cultural institutions and the convergence of rail transit and bus lines. In British English, the term " city centre" is most often used instead. History Origins The Oxford English Dictionary's first citation for "down town" or "downtown" dates to 1770, in reference to the center of Boston. Some have posited that the term "downtown" was coined in New York City, where it was in use by the 1830s to refer to the original town at the southern tip of the island of Manhattan.Fogelson, p. 10. As the town of New York grew into a city, the only direction it could grow on the island was toward the n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

National Zoological Park (United States)
The National Zoological Park, commonly known as the National Zoo, is one of the oldest zoos in the United States. It is part of the Smithsonian Institution and does not charge admission. Founded in 1889, its mission is to "provide engaging experiences with animals and create and share knowledge to save wildlife and habitats". The National Zoo has two campuses. The first is a urban park located at Rock Creek Park in Northwest Washington, D.C., 20 minutes from the National Mall by MetroRail. The other campus is the Smithsonian Conservation Biology Institute (SCBI; formerly known as the Conservation and Research Center) in Front Royal, Virginia. On this land, there are 180 species of trees, 850 species of woody shrubs and herbaceous plants, 40 species of grasses, and 36 different species of bamboo. The SCBI is a non-public facility devoted to training wildlife professionals in conservation biology and to propagating rare species through natural means and assisted reproduction. ...

Washington Post
''The Washington Post'' (also known as the ''Post'' and, informally, ''WaPo'') is an American daily newspaper published in Washington, D.C.

Overhead Trolley Wire
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, trolleybuses or trams. It is known variously as: * Overhead catenary * Overhead contact system (OCS) * Overhead equipment (OHE) * Overhead line equipment (OLE or OHLE) * Overhead lines (OHL) * Overhead wiring (OHW) * Traction wire * Trolley wire This article follows the International Union of Railways in using the generic term ''overhead line''. An overhead line consists of one or more wires (or rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regular intervals. The feeder stations are usually fed from a high-voltage electrical grid. Overview Electric trains that collect their current from overhead lines use a device such as a pantograph, bow collector or trolley pole. It presses against the underside of the lowest overhead wire, the contact wire. Current collectors ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
