![]() Small numbers were built in other European countries, including in France, Belgium, Spain, and Hungary, also at Dannemora, Sweden. By the time of his death, Newcomen and others had installed over a hundred of his engines, not only in the West Country and the Midlands but also in north Wales, near Newcastle and in Cumbria. "Although its first use was in coal-mining areas, Newcomen's engine was also used for pumping water out of the metal mines in his native West Country, such as the tin mines of Cornwall. Both of these steam engines were used to pump out water-filled coal mines.īecause Savery held a general patent covering all imagined uses of steam power, Newcomen and his partner John Calley persuaded Savery to join forces with them to exploit their invention until the expiration of Savery's patent in 1733. It is possible that Newcomen's Dudley engine was preceded by an engine Newcomen built a mile and a half east of Wolverhampton. Since the steam was under such low pressure, there was no risk of a dangerous boiler explosion. Newcomen engines were successful partly because they were very safe to operate. Newcomen's Dudley Castle beam engine is generally accepted as the first successful Newcomen engine. In 1712 Newcomen and his partner John Calley produced the first working atmospheric reciprocating engine, or Newcomen steam engine, for pumping water at the Conygree Coalworks near Dudley, England. ![]() Newcomen's reciprocating engine could pump water far higher than was possible using Savery's steam pump. The railway age had begun and George Stephenson was its guiding spirit.Around 1710 English ironmonger, Baptist lay preacher, and inventor Thomas Newcomen developed the atmospheric reciprocating engine, which unlike the steam pump ("The Miner's Friend") developed by Thomas Savery in 1698, employed a piston in a cylinder, the vacuum pulling the piston down to the bottom of the cylinder when water was injected into it, cooling the steam. By 1830 Stephenson’s new locomotive, the Rocket, which could achieve a speed of 36 miles per hour, was operating on the Liverpool and Manchester Railway in Lancashire with other ‘iron horses’ built in the factory he had now opened in Newcastle. This was the first outing of the world’s first public passenger steam train. In 1825 the engine, later called Locomotion, took 450 people 25 miles from Darlington to Stockton at 15 miles per hour. He was becoming a respected figure and in 1821 he persuaded a businessman who was planning a horse-drawn railway from Stockton-on-Tees to Darlington in County Durham to order a steam locomotive for the line. Stephenson went on to devise an improved type of railway track and he built more locomotives for Killingworth and other collieries. ![]() It was this that made Blucher the first fully effective steam railway locomotive. Not content with that, he soon dramatically improved the engine’s steam system to give it greater pulling power. There in 1814 he built a locomotive called Blucher (often spelled Blutcher) in honour of the Prussian general, which could haul eight waggons loaded with 30 tons of coal at a speed of four miles per hour. He worked at various other collieries in the area in the early 1800s, including the one at Killingworth north of Newcastle, and developed such skill with engines that in 1812 he was appointed ‘engine wright’, or chief mechanic, at Killingworth. He never went to school, but at 18 he was teaching himself to read and write (though writing would never be his strong suit) and was also getting basic tuition in arithmetic. His father worked in the Wylam colliery and so did young George from his early teens. ![]() He was born at Wylam in Northumberland in 1781, the son of illiterate working-class parents. Father or midwife, George Stephenson rose to fame from humble beginnings. Others followed his lead and Christian Wolmar in his book The Great Railway Revolution suggests that Stephenson, who had a talent for improving other people’s ideas, was not so much the father of the railways as their midwife. The most notable was Robert Trevithick, a Cornishman, who in 1803 built the first steam locomotive to run on rails, which were essential because an adequately powerful engine was too heavy for roads or wooden tracks. Within a few years of his death in 1848 George Stephenson was called ‘the father of the railways’, but that accolade has been challenged because there were other engineers involved in the development of the world’s first railway system.
