Steam power introduced edit see also: Steam locomotive james Watt, a scottish inventor and mechanical engineer, greatly improved the steam engine of Thomas Newcomen, hitherto used to pump water out of mines. Watt developed a reciprocating engine in 1769, capable of powering a wheel. Although the watt engine powered cotton mills and a variety of machinery, it was a large stationary engine. It could not be otherwise: the state of boiler technology necessitated the use of low pressure steam acting upon a vacuum in the cylinder; this required a separate condenser and an air pump. Nevertheless, as the construction of boilers improved, watt investigated the use of high-pressure steam acting directly upon a piston. This raised the possibility of a smaller engine, that might be used to power a vehicle and he patented a design for a steam locomotive in 1784. His employee william Murdoch produced a working model of a self-propelled steam carriage in that year.

Sometimes they lasted as little as one year under high traffic. All these developments in the handwriting production of iron eventually led to replacement of composite wood/iron rails with superior administrator all iron rails. The introduction of the bessemer process, enabling steel to be made inexpensively, led to the era of great expansion of railways that began in the late 1860s. Steel rails lasted several times longer than iron. Steel rails made heavier locomotives possible, allowing for longer trains and improving the productivity of railroads. 25 The bessemer process introduced nitrogen into the steel, which caused the steel to become brittle with age. The open hearth furnace began to replace the bessemer process near the end of the 19th century, improving the quality of steel and further reducing costs. Thus steel completely replaced the use of iron in rails, thus becoming standard for all railways. The first passenger horsecar or tram, swansea and Mumbles railway was opened between Swansea and Mumbles in Wales in 1807. 26 Horses remained the preferable mode for tram transport even after the arrival of steam engines, well till the end of the 19th century. The major reason was that the horse-cars were cleaner compared to steam driven trams which caused smoke in city streets.
Cast iron used in rails proved unsatisfactory because it was thesis brittle and broke under heavy loads. The wrought iron invented by john Birkinshaw in 1820 replaced cast iron. Wrought iron (usually simply referred to as "iron was a ductile material that could undergo considerable deformation before breaking, making it more suitable for iron rails. But iron was expensive to produce until Henry cort patented the puddling process in 1784. In 1783 Cort also patented the rolling process, which was 15 times faster at consolidating and shaping iron than hammering. 20 These processes greatly lowered the cost of producing iron and rails. The next important development in iron production was hot blast developed by james beaumont neilson (patented 1828 which considerably reduced the amount of coke (fuel) or charcoal needed to produce pig iron. 21 Wrought iron was a soft material that contained slag or dross. The softness and dross tended to make iron rails distort and delaminate and they lasted less than 10 years.
The plate rail was taken up by benjamin Outram for wagonways serving his canals, manufacturing them at his Butterley ironworks. In 1803, william Jessop opened the surrey iron railway, a double track plateway, erroneously sometimes cited as world's first public railway, in south London. 19 meanwhile, william Jessop had earlier used a form of all-iron edge rail and flanged wheels successfully for an extension to the Charnwood Forest Canal at Nanpantan, loughborough, leicestershire in 1789. In 1790, jessop and his partner Outram began to manufacture edge-rails. Jessop became a partner in the butterley company in 1790. The first public edgeway (thus also first public railway) built was lake lock rail road in 1796. Although the primary purpose of the line was to carry coal, it also carried passengers. These two systems of constructing iron railways, the "L" plate-rail and the smooth edge-rail, continued to exist side by side until well on into the early 19th century. The flanged wheel and edge-rail eventually proved its superiority and became the standard for railways.

This carried coal for James Clifford from his mines down to the essays river severn to be loaded onto barges and carried to riverside towns. 15 The wollaton Wagonway, completed in 1604 by huntingdon beaumont, has sometimes erroneously been cited as the earliest British railway. It ran from Strelley to wollaton near Nottingham. 16 The middleton railway in leeds, which was built in 1758, later became the world's oldest operational railway (other than funiculars albeit now in an upgraded form. In 1764, the first railway in the America was built in Lewiston, new York.
17 Metal rails introduced edit In the late 1760s, the coalbrookdale company began to fix plates of cast yogananda iron to the upper surface of the wooden rails. This allowed a variation of gauge to be used. At first only balloon loops could be used for turning, but later, movable points were taken into use that allowed for switching. 18 A replica of a "Little eaton Tramway" wagon, the tracks are plateways A system was introduced in which unflanged wheels ran on L-shaped metal plates these became known as plateways. John Curr, a sheffield colliery manager, invented this flanged rail in 1787, though the exact date of this is disputed.
In 1515, cardinal Matthäus Lang wrote a description of the reisszug, a funicular railway at the hohensalzburg Castle in Austria. The line originally used wooden rails and a hemp haulage rope and was operated by human or animal power, through a treadwheel. 8 The line still exists and is operational, although in updated form and is possibly the oldest operational railway. 9 Minecart shown in de re metallica (1556). The guide pin fits in a groove between two wooden planks. Wagonways (or tramways ) using wooden rails, hauled by horses, started appearing in the 1550s to facilitate the transport of ore tubs to and from mines, and soon became very popular in Europe.
Such an operation was illustrated in Germany in 1556 by georgius Agricola (image right) in his work de re metallica. 10 This line used "Hund" carts with unflanged wheels running on wooden planks and a vertical pin on the truck fitting into the gap between the planks to keep it going the right way. The miners called the wagons Hunde dogs from the noise they made on the tracks. 11 There are many references to their use in central Europe in the 16th century. 12 Such a transport system was later used by german miners at Caldbeck, cumbria, england, perhaps from the 1560s. 13 A wagonway was built at Prescot, near liverpool, sometime around 1600, possibly as early as 1594. Owned by Philip layton, the line carried coal from a pit near Prescot Hall to a terminus about half a mile away. 14 A funicular railway was also made at Broseley in Shropshire some time before 1604.

Following decline after World War ii due to competition from cars, rail transport has had a revival in recent decades due to road congestion and rising fuel prices, as well as governments investing in rail as a means of reducing CO2 emissions in the context. Contents History edit main article: History of rail transport The history of rail transport began in the 6th century bc in Ancient Greece. It can be divided up into several discrete periods defined by the principal means of track material and motive power used. Ancient systems edit evidence indicates that there was 6.5 km long diolkos paved trackway, which transported boats across the Isthmus of Corinth in Greece from around 600. Wheeled vehicles pulled by men and animals ran in grooves in limestone, which provided the track element, preventing the wagons from leaving the intended route. The diolkos was in use for over 650 years, until at least the 1st century. 5 The paved trackways were also later built in Roman Egypt. 6 7 Pre-steam edit see also: Funicular, business wagonway, tramway (industrial), and Plateway wooden rails introduced edit railways reappeared again only in the 14th century.
Prior to this, major towns and cities varied their local time relative to gmt. The invention and development of the railway in the United Kingdom was one of the most important technological inventions of the 19th century. The world's first underground railway, the metropolitan railway (part of the london Underground opened in 1863. In the 1880s, electrified trains were introduced, leading to electrification jul of tramways and rapid transit systems. Starting during the 1940s, the non-electrified railways in most countries had their steam locomotives replaced by diesel -electric locomotives, with the process being almost complete by the 2000s. During the 1960s, electrified high-speed railway systems were introduced in Japan and later in some other countries. Many countries are in process of replacing diesel locomotives with electric locomotives, mainly due to environmental concerns, a notable example being Switzerland, which has completely electrified its network. Other forms of guided ground transport outside the traditional railway definitions, such as monorail or maglev, have been tried but have seen limited use.
robert Stephenson and Company, the locomotion. 1 is the first steam locomotive to carry passengers on a public rail line, the Stockton and Darlington railway in 1825. George also built the first public inter-city railway line in the world to use only the steam locomotives all the time, the liverpool and Manchester railway which opened in 1830. With steam engines, one could construct mainline railways, which were a key component of the Industrial revolution. Also, railways reduced the costs of shipping, and allowed for fewer lost goods, compared with water transport, which faced occasional sinking of ships. The change from canals to railways allowed for "national markets" in which prices varied very little from city to city. The spread of the railway network and the use of railway timetables, led to the standardisation of time (railway time) in Britain based on Greenwich mean Time.
Columbus, Ohio in the United States, a gwr 7800 Class steam locomotive hauling the cambrian coast Express between. London and, pwllheli in the United Kingdom, rolling stock in a rail transport business system generally encounters lower frictional resistance than 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 facilities. Power is provided by locomotives which either draw electric power from a railway electrification system or produce their own power, usually by diesel engines. Most tracks are accompanied by a signalling system. Railways are a safe land transport system when compared to other forms of transport. Nb 1 railway transport is capable of high levels of passenger and cargo utilization and energy efficiency, but is often less flexible and more capital -intensive than road transport, when lower traffic levels are considered. The oldest known, man/animal-hauled railways date back to the 6th century bc in Corinth, greece. Rail transport then commenced in mid 16th century in Germany in form of horse-powered funiculars and wagonways.

Rail transport is a means of transferring of passengers and goods on essays wheeled vehicles running on rails, also known as tracks. It is also commonly referred to as train transport. In contrast to road transport, where 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 ties (sleepers) and ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as slab track, where the rails are fastened to a concrete foundation resting on a prepared subsurface.
