#Steam train trial#

On 21 February 1804, the first recorded steam-hauled railway journey took place as another of Trevithick's locomotives hauled a train along the 4 ft 4 in ( 1,321 mm)-wide tramway from the Pen-y-darren ironworks, near Merthyr Tydfil, to Abercynon in South Wales.

It was constructed for the Coalbrookdale ironworks in Shropshire in the United Kingdom though no record of it working there has survived. The first full-scale working railway steam locomotive was the 3 ft ( 914 mm) gauge Coalbrookdale Locomotive, built by Trevithick in 1802. Trevithick's 1802 Coalbrookdale locomotive The authenticity and date of this locomotive is disputed by some experts and a workable steam train would have to await the invention of the high-pressure steam engine by Richard Trevithick, who pioneered the use of steam locomotives.

The model still exists at the Ohio Historical Society Museum in Columbus, US. His steam locomotive used interior bladed wheels guided by rails or tracks. An early working model of a steam rail locomotive was designed and constructed by steamboat pioneer John Fitch in the US during 1794. A full-scale rail steam locomotive was proposed by William Reynolds around 1787. In 1784, William Murdoch, a Scottish inventor, built a small-scale prototype of a steam road locomotive in Birmingham. The earliest railways employed horses to draw carts along rail tracks.

In the United States, larger loading gauges allowed the development of very large, heavy locomotives such as the Union Pacific Big Boy, which weighed 540 long tons (550 t 600 short tons) and had a tractive effort of 135,375 pounds-force (602,180 newtons). Towards the end of the steam era, a longstanding British emphasis on speed culminated in a record, still unbroken, of 126 miles per hour (203 kilometres per hour) by LNER Class A4 4468 Mallard. Robert Stephenson and Company was the pre-eminent builder of steam locomotives in the first decades of steam for railways in the United Kingdom, the United States, and much of Europe. Rapid development ensued in 1830 George Stephenson opened the first public inter-city railway, the Liverpool and Manchester Railway, after the success of Rocket at the 1829 Rainhill Trials had proved that steam locomotives could perform such duties. 1, built by George Stephenson and his son Robert's company Robert Stephenson and Company, was the first steam locomotive to haul passengers on a public railway, the Stockton and Darlington Railway, in 1825. Salamanca, built in 1812 by Matthew Murray for the Middleton Railway, was the first commercially successful steam locomotive.

Richard Trevithick built the first steam locomotive known to have hauled a load over a distance at Pen-y-darren in 1804, although he produced an earlier locomotive for trial at Coalbrookdale in 1802. Steam locomotives were first developed in the United Kingdom during the early 19th century and used for railway transport until the middle of the 20th century. Variations in this general design include electrically-powered boilers, turbines in place of pistons, and using steam generated externally. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a tender coupled to it. In most locomotives, the steam is admitted alternately to each end of its cylinders in which pistons are mechanically connected to the locomotive's main wheels. Functionally, it is a steam engine on wheels. : 80 It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times. 41 018 climbing the Schiefe Ebene was pusher locomotive (video 34.4 MB)Ī steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. LNER Class A3 4472 Flying Scotsman was the first steam locomotive to officially reach 100 mph (160 km/h), on 30 November 1934. LNER Class A4 4468 Mallard is officially the fastest steam locomotive, reaching 126 mph (203 km/h) on 3 July 1938.
