Electrification Of The New York, New Haven, And Hartford Railroad
The New York, New Haven and Hartford Railroad pioneered electrification of main line railroads using high-voltage, alternating current, single-phase overhead catenary. It electrified its mainline between Stamford, Connecticut, and Woodlawn, New York, in 1907, and extended the electrification to New Haven, Connecticut, in 1914. While single-phase AC railroad electrification has become commonplace, the New Haven's system was unprecedented at the time of construction. The significance of this electrification was recognized in 1982 by its designation as a National Historic Engineering Landmark by the American Society of Mechanical Engineers (ASME). Initial experiments The New Haven tried several experiments with low-voltage DC electrification in the decade preceding their main line overhead electrification. These included: *1895 electrification of of line between Nantasket Junction and Pemberton, Massachusetts using overhead copper contact wire at 600-700 Vdc. *This line was ext ...

Grand Central Terminal
Grand Central Terminal (GCT; also referred to as Grand Central Station or simply as Grand Central) is a commuter rail terminal located at 42nd Street and Park Avenue in Midtown Manhattan, New York City. Grand Central is the southern terminus of the Metro-North Railroad's Harlem, Hudson and New Haven Lines, serving the northern parts of the New York metropolitan area. It also contains a connection to the New York City Subway at Grand Central–42nd Street station. The terminal is the second-busiest train station in North America, after New York Penn Station. The distinctive architecture and interior design of Grand Central Terminal's station house have earned it several landmark designations, including as a National Historic Landmark. Its Beaux-Arts design incorporates numerous works of art. Grand Central Terminal is one of the world's ten most-visited tourist attractions, with 21.6 million visitors in 2018, excluding train and subway passengers. The terminal's Main Conco ...

New York Central
The New York Central Railroad was a railroad primarily operating in the Great Lakes and Mid-Atlantic regions of the United States. The railroad primarily connected greater New York and Boston in the east with Chicago and St. Louis in the Midwest, along with the intermediate cities of Albany, Buffalo, Cleveland, Cincinnati, Detroit, Rochester and Syracuse. New York Central was headquartered in New York City's New York Central Building, adjacent to its largest station, Grand Central Terminal. The railroad was established in 1853, consolidating several existing railroad companies. In 1968, the NYC merged with its former rival, the Pennsylvania Railroad, to form Penn Central. Penn Central went bankrupt in 1970 and merged into Conrail in 1976. Conrail was broken-up in 1999, and portions of its system were transferred to CSX and Norfolk Southern Railway, with CSX acquiring most of the old New York Central trackage. Extensive trackage existed in the states of New York, Pennsylv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cos Cob Power Station
Cos Cob Power Station was a historic power station near the Metro-North Railroad tracks, the Mianus River and Sound Shore Drive in the Cos Cob area of Greenwich, Connecticut. The Spanish Revival style station building of 1907 was significant as part of the first mainline railroad electrification in the United States, using alternating current (AC) electrification. The New York City subway systems and a Hudson River railroad line used lower voltage direct current (DC) electrification, but for longer distances that would mean high transmission losses or frequent and closely spaced substations. A 1903 New York State law prohibited the use of steam locomotives in New York City. The New Haven line of the New York, New Haven and Hartford Railroad ran commuter trains into the city, and electrification all the way to New Haven would avoid massive congestion and delays to commuter trains if locomotives were changed at the New York City limits or at Stamford, CT. The "New Haven" chose AC ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London, Brighton And South Coast Railway
The London, Brighton and South Coast Railway (LB&SCR; known also as the Brighton line, the Brighton Railway or the Brighton) was a railway company in the United Kingdom from 1846 to 1922. Its territory formed a rough triangle, with London at its apex, practically the whole coastline of Sussex as its base, and a large part of Surrey. It was bounded on its western side by the London and South Western Railway (L&SWR), which provided an alternative route to Portsmouth. On its eastern side the LB&SCR was bounded by the South Eastern Railway (SER)—later one component of the South Eastern and Chatham Railway (SE&CR)—which provided an alternative route to Bexhill, St Leonards-on-Sea, and Hastings. The LB&SCR had the most direct routes from London to the south coast seaside resorts of Brighton, Eastbourne, Worthing, Littlehampton and Bognor Regis, and to the ports of Newhaven and Shoreham-by-Sea. It served the inland towns and cities of Chichester, Horsham, East Grinstead and Lewes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Three-phase AC Railway Electrification
Three-phase AC railway electrification was used in Italy, Switzerland and the United States in the early twentieth century. Italy was the major user, from 1901 until 1976, although lines through two tunnels also used the system; the Simplon Tunnel between Switzerland and Italy from 1906 to 1930 (but not connected to the Italian system), and the Cascade Tunnel of the Great Northern Railway in the United States from 1909 to 1939. The first standard gauge line was in Switzerland, from Burgdorf to Thun (), from 1899 to 1933. Advantages The system provides regenerative braking with the power fed back to the system, so is particularly suitable for mountain railways (provided the grid or another locomotive on the line can accept the power). The locomotives use three-phase induction motors. Lacking brushes and commutators, they require less maintenance. The early Italian and Swiss systems used a low frequency (16⅔ Hz), and a relatively low voltage (3,000 or 3,600 volts) compared wi ...

Baldwin-Westinghouse Electric Locomotives
Baldwin, the locomotive manufacturer, and Westinghouse, the promoter of AC (alternating current) electrification, joined forces in 1895 to develop AC railway electrification. Soon after the turn of the century, they marketed a single-phase high-voltage system to railroads. From 1904 to 1905 they supplied locomotives carrying a joint builder's plate to a number of American railroads, particularly for the New Haven (the New York, New Haven and Hartford Railroad) line from New York to New Haven, and other New Haven lines. Westinghouse would produce the motors, controls, and other electrical gear, while Baldwin would produce the running gear, frame, body, and (in most cases) perform final assembly. Baldwin-Westinghouse electric locomotives Experimental locomotives In 1895 a box-cab locomotive long with two four-wheel trucks and weighing was built at the East Pittsburgh (Pennsylvania) works of Westinghouse. It was used for more than a decade of AC and DC experimentation. Sol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baldwin Locomotive Works
The Baldwin Locomotive Works (BLW) was an American manufacturer of railroad locomotives from 1825 to 1951. Originally located in Philadelphia, it moved to nearby Eddystone, Pennsylvania, in the early 20th century. The company was for decades the world's largest producer of steam locomotives, but struggled to compete as demand switched to diesel locomotives. Baldwin produced the last of its 70,000-plus locomotives in 1951, before merging with the Lima-Hamilton Corporation on September 11, 1951, to form the Baldwin-Lima-Hamilton Corporation. The company has no relation to the E.M. Baldwin and Sons of New South Wales, Australia, a builder of small diesel locomotives for sugar cane railroads. History: 19th century Beginning The Baldwin Locomotive Works had a humble beginning. Matthias W. Baldwin, the founder, was a jeweler and whitesmith, who, in 1825, formed a partnership with machinist David H. Mason, and engaged in the manufacture of bookbinders' tools and cylinders for cal ...
