Description: George Stephenson George Stephenson (9 June 1781 – 12 August 1848) was an English civil engineer and mechanical engineer during the Industrial Revolution. Renowned as the "Father of Railways", Stephenson was considered by the Victorians as a great example of diligent application and thirst for improvement. His chosen rail gauge, sometimes called "Stephenson gauge",[i] was the basis for the 4-foot-8+1⁄2-inch (1.435 m) standard gauge used by most of the world's railways. George Stephenson Born 9 June 1781 Wylam, Northumberland, England Died 12 August 1848 (aged 67) Chesterfield, Derbyshire, England Resting place Holy Trinity Church, Chesterfield Spouse(s) Frances Henderson (1802–1806) Elizabeth Hindmarsh (1820–1845) Ellen Gregory (1848) Children Robert Stephenson Frances Stephenson (died in infancy) Pioneered by Stephenson, rail transport was one of the most important technological inventions of the 19th century and a key component of the Industrial Revolution. Built by George and his son Robert's company Robert Stephenson and Company, the Locomotion No. 1 was 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 locomotives, the Liverpool and Manchester Railway, which opened in 1830.

(June 2021) Further information: Safety lamp Stephenson's safety lamp shown with Davy's lamp on the left In 1815, aware of the explosions often caused in mines by naked flames, Stephenson began to experiment with a safety lamp that would burn in a gaseous atmosphere without causing an explosion. At the same time, the eminent scientist and Cornishman Humphry Davy was also looking at the problem. Despite his lack of scientific knowledge, Stephenson, by trial and error, devised a lamp in which the air entered via tiny holes, through which the flames of the lamp could not pass. A month before Davy presented his design to the Royal Society, Stephenson demonstrated his own lamp to two witnesses by taking it down Killingworth Colliery and holding it in front of a fissure from which firedamp was issuing. The two designs differed; Davy's lamp was surrounded by a screen of gauze, whereas Stephenson's prototype lamp had a perforated plate containing a glass cylinder. For his invention Davy was awarded £2000, whilst Stephenson was accused of stealing the idea from Davy, because he was not seen as an adequate scientist who could have produced the lamp by any approved scientific method. Stephenson, having come from the North-East, spoke with a broad Northumberland accent and not the 'Language of Parliament,' which made him seem lowly. Realizing this, he made a point of educating his son Robert in a private school, where he was taught to speak in Standard English with a Received Pronunciation accent. It was due to this, in their future dealings with Parliament, that it became clear that the authorities preferred Robert to his father. A local committee of enquiry gathered in support of Stephenson, exonerated him, proved he had been working separately to create the 'Geordie Lamp', and awarded him £1,000, but Davy and his supporters refused to accept their findings, and would not see how an uneducated man such as Stephenson could come up with the solution he had. In 1833 a House of Commons committee found that Stephenson had equal claim to having invented the safety lamp. Davy went to his grave believing that Stephenson had stolen his idea. The Stephenson lamp was used almost exclusively in North East England, whereas the Davy lamp was used everywhere else. The experience gave Stephenson a lifelong distrust of London-based, theoretical, scientific experts. In his book George and Robert Stephenson, the author L.T.C. Rolt relates that opinion varied about the two lamps' efficiency: that the Davy Lamp gave more light, but the Geordie Lamp was thought to be safer in a more gaseous atmosphere. He made reference to an incident at Oaks Colliery in Barnsley where both lamps were in use. Following a sudden strong influx of gas the tops of all the Davy Lamps became red hot (which had in the past caused an explosion, and in so doing risked another), whilst all the Geordie Lamps simply went out. There is a theory that it was Stephenson who indirectly gave the name of "Geordies" to the people of the North East of England. By this theory, the name of the Geordie Lamp attached to the North East pit men themselves. By 1866 any native of Newcastle upon Tyne could be called a Geordie. Locomotives Cornishman Richard Trevithick is credited with the first realistic design for a steam locomotive, the "Puffing Devil", in 1801.[11][12] Later, he visited Tyneside and built an engine there for a mine-owner. Several local men were inspired by this, and designed their own engines.[citation needed] Early Stephenson locomotive in Samuel Smiles' Lives of the Engineers (1862).[7] Called an 1816 Killingworth Colliery locomotive (often claimed to be Blücher), it looks more like the slightly later Hetton colliery railway locomotives whose 1852 replica Lyons was still operating in Smiles' time. Stephenson designed his first locomotive in 1814, a travelling engine designed for hauling coal on the Killingworth wagonway named Blücher after the Prussian general Gebhard Leberecht von Blücher (It was suggested the name sprang from Blücher's rapid march of his army in support of Wellington at Waterloo).[ii] Blücher was modelled on Matthew Murray's locomotive Willington, which George studied at Kenton and Coxlodge colliery on Tyneside, and was constructed in the colliery workshop behind Stephenson's home, Dial Cottage, on Great Lime Road. The locomotive could haul 30 tons of coal up a hill at 4 mph (6.4 km/h), and was the first successful flanged-wheel adhesion locomotive: its traction depended on contact between its flanged wheels and the rail. Altogether, Stephenson is said to have produced 16 locomotives at Killingworth, although it has not proved possible to produce a convincing list of all 16. Of those identified, most were built for use at Killingworth or for the Hetton colliery railway. A six-wheeled locomotive was built for the Kilmarnock and Troon Railway in 1817 but was withdrawn from service because of damage to the cast-iron rails. Another locomotive was supplied to Scott's Pit railroad at Llansamlet, near Swansea, in 1819 but it too was withdrawn, apparently because it was under-boilered and again caused damage to the track. Fishbelly rail with half-lap joint, patented by Stephenson 1816 The new engines were too heavy to run on wooden rails or plate-way, and iron edge rails were in their infancy, with cast iron exhibiting excessive brittleness. Together with William Losh, Stephenson improved the design of cast-iron edge rails to reduce breakage; rails were briefly made by Losh, Wilson and Bell at their Walker ironworks. According to Rolt, Stephenson managed to solve the problem caused by the weight of the engine on the primitive rails. He experimented with a steam spring (to 'cushion' the weight using steam pressure acting on pistons to support the locomotive frame), but soon followed the practice of 'distributing' weight by using a number of wheels or bogies. For the Stockton and Darlington Railway Stephenson used wrought-iron malleable rails that he had found satisfactory, notwithstanding the financial loss he suffered by not using his own patented design. Hetton Railway Stephenson was hired to build the eight-mile (13-km) Hetton colliery railway in 1820. He used a combination of gravity on downward inclines and locomotives for level and upward stretches. This, the first railway using no animal power, opened in 1822. This line used a gauge of 4 ft 8 in (1,422 mm) which Stephenson had used before at the Killingworth wagonway. Other locomotives include: 1817–1824 The Duke for the Kilmarnock and Troon Railway The First Railway Stockton and Darlington Railway The No. 1 engine, called Locomotion, for the Stockton & Darlington Railway In 1821, a parliamentary bill was passed to allow the building of the Stockton and Darlington Railway (S&DR). The 25-mile (40 km) railway connected collieries near Bishop Auckland to the River Tees at Stockton, passing through Darlington on the way. The original plan was to use horses to draw coal carts on metal rails, but after company director Edward Pease met Stephenson, he agreed to change the plans. Stephenson surveyed the line in 1821, and assisted by his 18-year-old son Robert, construction began the same year. Experiment, the first railway carriage A manufacturer was needed to provide the locomotives for the line. Pease and Stephenson had jointly established a company in Newcastle to manufacture locomotives. It was set up as Robert Stephenson and Company, and George's son Robert was the managing director. A fourth partner was Michael Longridge of Bedlington Ironworks.[8] On an early trade card, Robert Stephenson & Co was described as "Engineers, Millwrights & Machinists, Brass & Iron Founders". In September 1825, the works at Forth Street, Newcastle, completed the first locomotive for the railway: originally named Active, it was renamed Locomotion and was followed by Hope, Diligence and Black Diamond. The Stockton and Darlington Railway opened on 27 September 1825. Driven by Stephenson, Locomotion hauled an 80-ton load of coal and flour nine miles (14 km) in two hours, reaching a speed of 24 miles per hour (39 kilometres per hour) on one stretch. The first purpose-built passenger car, Experiment, was attached and carried dignitaries on the opening journey. It was the first time passenger traffic had been run on a steam locomotive railway.[8] The rails used for the line were wrought-iron, produced by John Birkinshaw at the Bedlington Ironworks. Wrought-iron rails could be produced in longer lengths than cast-iron and were less liable to crack under the weight of heavy locomotives. William Losh of Walker Ironworks thought he had an agreement with Stephenson to supply cast-iron rails, and Stephenson's decision caused a permanent rift between them. The gauge Stephenson chose for the line was 4 feet 8+1⁄2 inches (1,435 mm) which subsequently was adopted as the standard gauge for railways, not only in Britain, but throughout the world. Liverpool and Manchester Railway Statue of George Stephenson at the National Railway Museum, York First passenger railway, L&MR Stephenson had ascertained by experiments at Killingworth that half the power of the locomotive was consumed by a gradient as little as 1 in 260.[19] He concluded that railways should be kept as level as possible. He used this knowledge while working on the Bolton and Leigh Railway, and the Liverpool and Manchester Railway (L&MR), executing a series of difficult cuttings, embankments and stone viaducts to level their routes. Defective surveying of the original route of the L&MR caused by hostility from some affected landowners meant Stephenson encountered difficulty during Parliamentary scrutiny of the original bill, especially under cross-examination by Edward Hall Alderson. The bill was rejected and a revised bill for a new alignment was submitted and passed in a subsequent session. The revised alignment presented the problem of crossing Chat Moss, an apparently bottomless peat bog, which Stephenson overcame by unusual means, effectively floating the line across it.[8] The method he used was similar to that used by John Metcalf who constructed many miles of road across marshes in the Pennines, laying a foundation of heather and branches, which became bound together by the weight of the passing coaches, with a layer of stones on top. As the L&MR approached completion in 1829, its directors arranged a competition to decide who would build its locomotives, and the Rainhill Trials were run in October 1829. Entries could weigh no more than six tons and had to travel along the track for a total distance of 60 miles (97 km). Stephenson's entry was Rocket, and its performance in winning the contest made it famous. George's son Robert had been working in South America from 1824 to 1827 and returned to run the Forth Street Works while George was in Liverpool overseeing the construction of the line. Robert was responsible for the detailed design of Rocket, although he was in constant postal communication with his father, who made many suggestions. One significant innovation, suggested by Henry Booth, treasurer of the L&MR, was the use of a fire-tube boiler, invented by French engineer Marc Seguin that gave improved heat exchange. The opening ceremony of the L&MR, on 15 September 1830, drew luminaries from the government and industry, including the Prime Minister, the Duke of Wellington. The day started with a procession of eight trains setting out from Liverpool. The parade was led by Northumbrian driven by George Stephenson, and included Phoenix driven by his son Robert, North Star driven by his brother Robert and Rocket driven by assistant engineer Joseph Locke. The day was marred by the death of William Huskisson, the Member of Parliament for Liverpool, who was struck by Rocket. Stephenson evacuated the injured Huskisson to Eccles with a train, but he died from his injuries. Despite the tragedy, the railway was a resounding success. Stephenson became famous, and was offered the position of chief engineer for a wide variety of other railways. Stephenson's skew arch bridge Stephenson's bridge A close-up of the technique 1830 also saw the grand opening of the skew bridge in Rainhill over the Liverpool and Manchester Railway. The bridge was the first to cross any railway at an angle.[20] It required the structure to be constructed as two flat planes (overlapping in this case by 6 ft (1.8 m)) between which the stonework forms a parallelogram shape when viewed from above. It has the effect of flattening the arch and the solution is to lay the bricks forming the arch at an angle to the abutments (the piers on which the arches rest). The technique, which results in a spiral effect in the arch masonry, provides extra strength in the arch to compensate for the angled abutments. The bridge is still in use at Rainhill station, and carries traffic on the A57 (Warrington Road). The bridge is a listed structure.
