George Stephenson
George Stephenson was a British civil engineer and mechanical engineer. 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", was the basis for the standard gauge used by most of the world's railways.
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. Following this, according to Encyclopedia Britannica, "Stephenson continued as the chief guide of the revolutionary transportation medium, solving problems of roadway construction, bridge design, and locomotive and rolling-stock manufacture. He built many other railways in the Midlands, and he acted as consultant on many railroad projects at home and abroad."
Childhood
George Stephenson was born on 9 June 1781 in Wylam, Northumberland, which is 9 miles west of Newcastle upon Tyne. He was the second child of Robert and Mabel Stephenson, neither of whom could read or write. Robert was the fireman for Wylam Colliery pumping engine, earning a very low wage, so there was no money for schooling. At 17, Stephenson became an engineman at Water Row Pit in Newburn nearby. George realised the value of education and paid to study at night school to learn reading, writing and arithmetic – he was illiterate until the age of 18.In 1801 he began work at Black Callerton Colliery south of Ponteland as a 'brakesman', controlling the winding gear at the pit. In 1802 he married Frances Henderson and moved to Willington Quay, east of Newcastle. There he worked as a brakesman while they lived in one room of a cottage. George made shoes and mended clocks to supplement his income.
Their first child Robert was born in 1803, and in 1804 they moved to Dial Cottage at West Moor, near Killingworth where George worked as a brakesman at Killingworth Pit. Their second child, a daughter, was born in July 1805. She was named Frances after her mother. The child died after just three weeks and was buried in St Bartholomew's Church, Long Benton north of Newcastle.
In 1806 George's wife Frances died of consumption, which would nowadays be termed as tuberculosis. She was buried in the same churchyard as their daughter on 16 May 1806, though the location of the grave is lost.
George decided to find work in Scotland and left Robert with a local woman while he went to work in Montrose in Scotland. After a few months he returned, probably because his father had been blinded in a mining accident. He moved back into a cottage at West Moor and his unmarried sister Eleanor moved in to look after Robert. In 1811 the pumping engine at High Pit, Killingworth was not working properly and Stephenson offered to improve it. He did so with such success that he was promoted to enginewright for the collieries at Killingworth, responsible for maintaining and repairing all the colliery engines. He became an expert in steam-driven machinery.
Early projects
The Safety Lamp
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, 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 steam engine research and development, leading to what has been variously described as "the first steam-powered passenger vehicle", or "his first high-pressure steam locomotive", in both cases referring to his unveiling and testing of the "Puffing Devil" on 24 December 1801. This was a result of his refinements of the steam engine of James Watt toward "strong steam", Watt believing this direction of development too dangerous. Evident from both accounts is that this first strong steam "locomotive" operated without tracks, because it was three years later that Trevithick was successful in producing a steam engine that operated on rails. 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.File:Killingworth-locomotive.jpg|thumb|234px|Early Stephenson locomotive in Samuel Smiles' Lives of the Engineers. Called an 1816 Killingworth Colliery locomotive, 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. 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, 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.
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, 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 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 which Stephenson had used before at the Killingworth wagonway.Other locomotives include:
