Tacubaya Railroad
Tacubaya Railroad (''Ferrocarril de Tacubaya'') was a , narrow gauge line serving an amusement park in the Tacubaya district of Mexico City. The line was built by Fernando de Teresa in 1896. Passengers were carried in several designs of roofed cars approximately long. The locomotives were smaller than those used at Disneyland. The first locomotive was based on Decauville equipment; and the second, a 6-ton 4-4-0, was the smallest ever built by Baldwin for commercial purposes.

Railway Companies Disestablished In 1910
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer faciliti ...

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 fo ...

Magdeburg
Magdeburg (; nds, label=Low Saxon, Meideborg ) is the capital and second-largest city of the German state Saxony-Anhalt. The city is situated at the Elbe river. Otto I, the first Holy Roman Emperor and founder of the Archdiocese of Magdeburg, was buried in the city's cathedral after his death. Magdeburg's version of German town law, known as Magdeburg rights, spread throughout Central and Eastern Europe. In the Late Middle Ages, Magdeburg was one of the largest and most prosperous German cities and a notable member of the Hanseatic League. One of the most notable people from the city is Otto von Guericke, famous for his experiments with the Magdeburg hemispheres. Magdeburg has been destroyed twice in its history. The Catholic League sacked Magdeburg in 1631, resulting in the death of 25,000 non-combatants, the largest loss of the Thirty Years' War. During the World War II the Allies bombed the city in 1945 and destroying much of it. After World War II the city belonge ...

Hermann Gruson
Hermann August Jacques Gruson (March 13, 1821, in Magdeburg – January 30, 1895) was a German engineer, inventor and industrial entrepreneur. Life Hermann Gruson was a descendant of a Huguenot immigrant family, and son of Prime Minister Lieutenant Louis Abraham Gruson in Magdeburg citadel. He attended the Domgymnasium Magdeburg, but then switched to the industrial and trade school, which he graduated in 1839, and did his military service as a one-year volunteer in a pioneer unit. He then attended the University of Berlin. He concentrated mainly on scientific and mathematical subjects and also attended lectures of his uncle Johann Philipp Gruson. Gruson then worked for five years in the engineering works of August Borsig, who was friends with his father, and learned machining. Borsig was able to place Gruson in a job with the Berlin-Hamburg railway, which he held between 1843 and 1851. In November 1847, Gruson rescued a boy who was drowning, and was awarded a medal for saving ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arnold Jung Lokomotivfabrik
The Arnold Jung Lokomotivfabrik (Arnold Jung Locomotive Works) was a locomotive manufacturer, in particular of Feldbahn locomotives, in Kirchen, Rheinland-Pfalz, Germany. History The firm was founded on 13 February 1885 as Jung & Staimer OHG by Arnold Jung and Christian Staimer. On 3 September 1885 the first locomotive was delivered. In 1913 the company was renamed Arnold Jung Lokomotivfabrik GmbH, Jungenthal. In 1976 locomotive production was stopped in favour of other products such as machine tools, transporters, armour plating, cranes and bridgelayers. Jung built more than 12,000 locomotives. In the 1950s it built 51 DB Class 23 2-6-2 locomotives, including in 1959, number 23 105, the last new steam locomotive supplied to the Deutsche Bundesbahn. Jung also made boilers for other uses such as steam rollers. By the 1950s Jung was also building diesel locomotives, such as the 42 standard gauge Egyptian Republic Railways 4211 class The Egyptian Republic Railways 421 ...

Narrow Gauge Railway
A narrow-gauge railway (narrow-gauge railroad in the US) is a railway with a track gauge narrower than standard . Most narrow-gauge railways are between and . Since narrow-gauge railways are usually built with tighter curves, smaller structure gauges, and lighter rails, they can be less costly to build, equip, and operate than standard- or broad-gauge railways (particularly in mountainous or difficult terrain). Lower-cost narrow-gauge railways are often used in mountainous terrain, where engineering savings can be substantial. Lower-cost narrow-gauge railways are often built to serve industries as well as sparsely populated communities where the traffic potential would not justify the cost of a standard- or broad-gauge line. Narrow-gauge railways have specialised use in mines and other environments where a small structure gauge necessitates a small loading gauge. In some countries, narrow gauge is the standard; Japan, Indonesia, Taiwan, New Zealand, South Africa, and the A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Streetcars In Mexico City
Mexico City once had an extensive network of streetcars. Most tram, streetcar lines in Mexico City radiated from the city's central square, the Zócalo towards many parts of the city. By the 1980s only one streetcar line survived, which itself was converted into the Xochimilco Light Rail line in 1986. History At the beginning of the 19th century, Mexico City was in need of new means of transportation. Since the 1830s efforts had been made to build a railway. In 1840, 1849, and 1959, various concessions were granted to build a permanent urban railway without any result. In 1856, an American Texan, George Louis Hammeken, was granted a concession to build an animal-powered street railway from the Zócalo, Mexico City's central square, to Tacubaya, now in the west-central part of the city. The Ferrocarril de Tacubaya opened on January 1, 1858. July 4, 1858, president Ignacio Comonfort opened the first railway line between Mexico City and Villa Guadalupe (La Villa). In 1868 the ...

Track Gauge Conversion
Gauge conversion is the changing of one railway track gauge (the distance between the running rails) to another. Sleepers If tracks are converted to a narrower gauge, the existing sleepers (ties) may be used. However, replacement is required if the conversion is to a wider gauge. Some sleepers may be long enough to accommodate the fittings of both existing and alternative gauges. Wooden sleepers are suitable for conversion because they can be drilled for the repositioned rail spikes. Being difficult to drill, concrete sleepers are less suitable for conversion. Concrete sleepers may be cast with alternative gauge fittings in place, an example being those used during the conversion of the Melbourne–Adelaide railway from to . Steel sleepers may have alternative gauge fittings cast at production, may be drilled for new fittings or may be welded with new fittings. Structures Conversion from a narrow to a wider gauge may require enlargement of the structure gauge of the bridg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
