Wendel Bollman
Wendel Bollman (January 21, 1814 – 1884) was an American self-taught civil engineer, best known for his iron railway bridges. Only one of his patented "Bollman truss" bridges survives, the Bollman Truss Railroad Bridge in Savage, Maryland. The Wells Creek Bollman Bridge near Meyersdale, Pennsylvania is also standing, although that bridge uses the Warren truss system. Early life and career Bollman was born in Baltimore, Maryland to German immigrants, and was the seventh of eight children. His father died when Wendell was 11, and he quit school to support his family. Bollman began his career with the Baltimore and Ohio Railroad (B&O) as a carpenter in 1828, just as the B&O began laying track. He left shortly thereafter to build houses. During this period he married Ann Smith; the couple would have 10 children. In 1837 he returned to the B&O as a carpenter, but was soon promoted to line foreman by Benjamin H. Latrobe, II. Although the early B&O bridges in central Mar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

This was one of the earliest passenger stations in the United States. Following the 1830 manufacture of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
B & O Railroad Potomac River Crossing
The B & O Railroad Potomac River Crossing is a historic site where a set of railroad bridges, originally built by the Baltimore and Ohio Railroad, span the Potomac River between Sandy Hook, Maryland, and Harpers Ferry, West Virginia, in the United States. The site was added to the National Register of Historic Places on February 14, 1978 for its significance in commerce, engineering, industry, invention, and transportation. With History The original Harper's Ferry operated from 1733 until it was replaced by a timber covered road bridge in about 1824 at the confluence of the Potomac and Shenandoah Rivers. Built in 1836–1837, the B&O's first crossing over the Potomac was an covered wood truss. It was the only rail crossing of the Potomac River until after the Civil War. The single-track bridge, which comprised six river spans plus a span over the Chesapeake and Ohio Canal, was designed by Benjamin Henry Latrobe, II. In 1837 the Winchester and Potomac Railroad reached Harpers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It was set up through the Historic Places Act 1954 with a mission to "...promote the identification, protection, preservation and conservation of the historical and cultural heritage of New Zealand" and is an autonomous Crown entity. Its current enabling legislation is the Heritage New Zealand Pouhere Taonga Act 2014. History Charles Bathurst, 1st Viscount Bledisloe gifted the site where the Treaty of Waitangi was signed to the nation in 1932. The subsequent administration through the Waitangi Trust is sometimes seen as the beginning of formal heritage protection in New Zealand. Public discussion about heritage protection occurred in 1940 in conjunction with t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Island
The South Island, also officially named , is the larger of the two major islands of New Zealand in surface area, the other being the smaller but more populous North Island. It is bordered to the north by Cook Strait, to the west by the Tasman Sea, and to the south and east by the Pacific Ocean. The South Island covers , making it the world's 12th-largest island. At low altitude, it has an oceanic climate. The South Island is shaped by the Southern Alps which run along it from north to south. They include New Zealand's highest peak, Aoraki / Mount Cook at . The high Kaikōura Ranges lie to the northeast. The east side of the island is home to the Canterbury Plains while the West Coast is famous for its rough coastlines such as Fiordland, a very high proportion of native bush and national parks, and the Fox and Franz Josef Glaciers. The main centres are Christchurch and Dunedin. The economy relies on agriculture and fishing, tourism, and general manufacturing and services. ...

Great Allegheny Passage
The Great Allegheny Passage (GAP) is a rail trail between Pittsburgh, Pennsylvania and Cumberland, Maryland. Together with the C&O Canal towpath, the GAP is part of a route between Pittsburgh and Washington, D.C., that is popular with through hikers and cyclists. History The GAP follows former right-of-way of the Baltimore and Ohio Railroad, Pittsburgh and Lake Erie Railroad, Union Railroad, and Western Maryland Railway. The first section of the GAP— near Ohiopyle—opened in 1986. The section between Woodcock Hollow and Cumberland opened on December 13, 2006. The GAP was completed in 2013 when the section between West Homestead and Point State Park in Pittsburgh opened. The completion project was named ''The Point Made'', reflecting the fact that it was now possible to reach Point State Park from Washington, D.C. Celebrations took place on June 15, 2013. With its opening, Pennsylvania became the state with the most rail trails—, with more under development. The ove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Industrial Spur
A branch line is a phrase used in railway terminology to denote a secondary railway line which branches off a more important through route, usually a main line. A very short branch line may be called a spur line. Industrial spur An industrial spur is a type of secondary track used by railroads to allow customers at a location to load and unload railcars without interfering with other railroad operations. Industrial spurs can vary greatly in length and railcar capacity depending on the requirements of the customer the spur is serving. In heavily industrialized areas, it is not uncommon for one industrial spur to have multiple sidings to several different customers. Typically, spurs are serviced by local trains responsible for collecting small numbers of railcars and delivering them to a larger yard, where these railcars are sorted and dispatched in larger trains with other cars destined to similar locations. Because industrial spurs generally have less capacity and traffic t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cast Iron
Cast iron is a class of iron–carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applications and are ...

Wrought Iron
Wrought iron is an iron alloy with a very low carbon content (less than 0.08%) in contrast to that of cast iron (2.1% to 4%). It is a semi-fused mass of iron with fibrous slag Inclusion (mineral), inclusions (up to 2% by weight), which give it a wood-like "grain" that is visible when it is etched, rusted, or bent to structural failure, failure. Wrought iron is tough, malleable, ductile, corrosion resistant, and easily forge welding, forge welded, but is more difficult to welding, weld electrically. Before the development of effective methods of steelmaking and the availability of large quantities of steel, wrought iron was the most common form of malleable iron. It was given the name ''wrought'' because it was hammered, rolled, or otherwise worked while hot enough to expel molten slag. The modern functional equivalent of wrought iron is Carbon steel#Mild or low-carbon steel, mild steel, also called low-carbon steel. Neither wrought iron nor mild steel contain enough carbon to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Locomotive
A locomotive or engine is a rail transport vehicle that provides the Power (physics), motive power for a train. If a locomotive is capable of carrying a payload, it is usually rather referred to as a multiple unit, Motor coach (rail), motor coach, railcar or power car; the use of these self-propelled vehicles is increasingly common for passenger trains, but rare for freight (see CargoSprinter). Traditionally, locomotives pulled trains from the front. However, Push-pull train, push-pull operation has become common, where the train may have a locomotive (or locomotives) at the front, at the rear, or at each end. Most recently railroads have begun adopting DPU or distributed power. The front may have one or two locomotives followed by a mid-train locomotive that is controlled remotely from the lead unit. __TOC__ Etymology The word ''locomotive'' originates from the Latin language, Latin 'from a place', Ablative case, ablative of 'place', and the Medieval Latin 'causing mot ...
