After private education and an engineering apprenticeship, Crampton worked under Marc Brunel, Daniel Gooch and the Rennie brothers before setting up as a civil engineer in 1848. His developing ideas on locomotive design were expressed through a series of five patents taken out between 1842 and 1849, each making a multiplicity of claims. The most typical feature of the Crampton locomotive, however, was a single pair of driving wheels set to the rear of the firebox. This meant they could be of large diameter, while the centre of gravity of the locomotive remained low, for the boiler barrel, though large, had only small carrying-wheels beneath it. The cylinders were approximately midway along the boiler and were outside the frames, as was the valve gear. The result was a steady-riding locomotive which neither pitched about a central driving axle nor hunted from side to side, as did other contemporary locomotives, and its working parts were unusually accessible for maintenance. However, adhesive weight was limited and the long wheelbase tended to damage track. Locomotives of this type were soon superseded on British railways, although they lasted much longer in Germany and France. Locomotives built to the later patents incorporated a long, coupled wheelbase with drive through an intermediate crankshaft, but they mostly had only short lives. In 1851 Crampton, with associates, laid the first successful submarine electric telegraph cable. The previous year the brothers Jacob and John Brett had laid a cable, comprising a copper wire insulated with gutta-percha, beneath the English Channel from Dover to Cap Gris Nez: signals were passed but within a few hours the cable failed. Crampton joined the Bretts' company, put up half the capital needed for another attempt, and designed a much stronger cable. Four gutta-percha-insulated copper wires were twisted together, surrounded by tarred hemp and armoured by galvanized iron wires; this cable was successful.

Crampton was also active in railway civil engineering and in water and gas engineering, and c. 1882 he invented a hydraulic tunnel-boring machine intended for a Channel tunnel.

Hackworth trained under his father, who was Foreman Blacksmith at Wylam colliery, and succeeded him upon his death in 1807. Between 1812 and 1816 he helped to build and maintain the Wylam locomotives under William Hedley. He then moved to Walbottle colliery, but during 1824 he took temporary charge of Robert Stephenson \& Co.'s works while George Stephenson was surveying the Liverpool \& Manchester Railway and Robert Stephenson was away in South America. In May 1825 Hackworth was appointed to the Stockton \& Darlington Railway (S \& DR) "to have superintendence of the permanent (i.e. stationary) and locomotive engines". He established the workshops at Shildon, and when the railway opened in September he became in effect the first locomotive superintendent of a railway company. From experience of operating Robert Stephenson \& Co.'s locomotives he was able to make many detail improvements, notably spring safety valves. In 1827 he designed and built the locomotive Royal George, with six wheels coupled and inverted vertical cylinders driving the rear pair. From the pistons, drive was direct by way of piston rods and connecting rods to crankpins on the wheels, the first instance of the use of this layout on a locomotive. Royal George was the most powerful and satisfactory locomotive on the S \& DR to date and was the forerunner of Hackworth's type of heavy-goods locomotive, which was built until the mid-1840s.

For the Rainhill Trials in 1829 Hackworth built and entered the locomotive Sans Pareil, which was subsequently used on the Bol ton \& Leigh Railway and is now in the Science Museum, London. A working replica was built for the 150th anniversary of the Liverpool \& Manchester Railway in 1980. In 1833 a further agreement with the S \& DR enabled Hackworth, while remaining in charge of their locomotives, to set up a locomotive and engineering works on his own account. Its products eventually included locomotives for the London, Brighton \& South Coast and York, Newcastle \& Berwick Railways, as well as some of the earliest locomotives exported to Russia and Canada. Hackworth's son, John Wesley Hackworth, was also an engineer and invented the radial valve gear for steam engines that bears his name.

The Wylam wagonway passed Newburn, and Hedley, who went to school at Wylam, must have been familiar with this wagonway from childhood. It had been built c.1748 to carry coal from Wylam Colliery to the navigable limit of the Tyne at Lemington. In 1805 Hedley was appointed viewer, or manager, of Wylam Colliery by Christopher Blackett, who had inherited the colliery and wagonway in 1800. Unlike most Tyneside wagonways, the gradient of the Wylam line was insufficient for loaded wagons to run down by gravity and they had to be hauled by horses. Blackett had a locomotive, of the type designed by Richard Trevithick, built at Gateshead as early as 1804 but did not take delivery, probably because his wooden track was not strong enough. In 1808 Blackett and Hedley relaid the wagonway with plate rails of the type promoted by Benjamin Outram, and in 1812, following successful introduction of locomotives at Middleton by John Blenkinsop, Blackett asked Hedley to investigate the feasibility of locomotives at Wylam. The expense of re-laying with rack rails was unwelcome, and Hedley experimented to find out the relationship between the weight of a locomotive and the load it could move relying on its adhesion weight alone. He used first a model test carriage, which survives at the Science Museum, London, and then used a full-sized test carriage laden with weights in varying quantities and propelled by men turning handles. Having apparently satisfied himself on this point, he had a locomotive incorporating the frames and wheels of the test carriage built. The work was done at Wylam by Thomas Waters, who was familiar with the 1804 locomotive, Timothy Hackworth, foreman smith, and Jonathan Forster, enginewright. This locomotive, with cast-iron boiler and single cylinder, was unsatisfactory: Hackworth and Forster then built another locomotive to Hedley's design, with a wrought-iron return-tube boiler, two vertical external cylinders and drive via overhead beams through pinions to the two axles. This locomotive probably came into use in the spring of 1814: it performed well and further examples of the type were built. Their axle loading, however, was too great for the track and from about 1815 each locomotive was mounted on two four-wheeled bogies, the bogie having recently been invented by William Chapman. Hedley eventually left Wylam in 1827 to devote himself to other colliery interests. He supported the construction of the Clarence Railway, opened in 1833, and sent his coal over it in trains hauled by his own locomotives. Two of his Wylam locomotives survive— Puffing Billy at the Science Museum, London, and Wylam Dilly at the Royal Museum of Scotland, Edinburgh—though how much of these is original and how much dates from the period 1827–32, when the Wylam line was re-laid with edge rails and the locomotives reverted to four wheels (with flanges), is a matter of mild controversy.

Stevens, a wealthy landowner with an estate at Hoboken on the Hudson River, had his attention drawn to the steamboat of John Fitch in 1786, and thenceforth devoted much of his time and fortune to developing steamboats and mechanical transport. He also had political influence and it was at his instance that Congress in 1790 passed an Act establishing the first patent laws in the USA. The following year Stevens was one of the first recipients of a US patent. This referred to multi-tubular boilers, of both watertube and firetube types, and antedated by many years the work of both Henry Booth and Marc Seguin on the latter.

A steamboat built in 1798 by John Stevens, Nicholas J.Roosevelt and Stevens's brother-in-law, Robert R.Livingston, in association was unsuccessful, nor was Stevens satisfied with a boat built in 1802 in which a simple rotary steam-en-gine was mounted on the same shaft as a screw propeller. However, although others had experimented earlier with screw propellers, when John Stevens had the Little Juliana built in 1804 he produced the first practical screw steamboat. Steam at 50 psi (3.5 kg/cm²) pressure was supplied by a watertube boiler to a single-cylinder engine which drove two contra-rotating shafts, upon each of which was mounted a screw propeller. This little boat, less than 25 ft (7.6 m) long, was taken backwards and forwards across the Hudson River by two of Stevens's sons, one of whom, R.L. Stevens, was to help his father with many subsequent experiments. The boat, however, was ahead of its time, and steamships were to be driven by paddle wheels until the late 1830s.

In 1807 John Stevens declined an invitation to join with Robert Fulton and Robert R.Living-ston in their development work, which culminated in successful operation of the PS Clermont that summer; in 1808, however, he launched his own paddle steamer, the Phoenix. But Fulton and Livingston had obtained an effective monopoly of steamer operation on the Hudson and, unable to reach agreement with them, Stevens sent Phoenix to Philadelphia to operate on the Delaware River. The intervening voyage over 150 miles (240 km) of open sea made Phoenix the first ocean-going steamer.

From about 1810 John Stevens turned his attention to the possibilities of railways. He was at first considered a visionary, but in 1815, at his instance, the New Jersey Assembly created a company to build a railway between the Delaware and Raritan Rivers. It was the first railway charter granted in the USA, although the line it authorized remained unbuilt. To demonstrate the feasibility of the steam locomotive, Stevens built an experimental locomotive in 1825, at the age of 76. With flangeless wheels, guide rollers and rack-and-pinion drive, it ran on a circular track at his Hoboken home; it was the first steam locomotive to be built in America.

Churchward was articled to the Locomotive Superintendent of the South Devon Railway in 1873, and when the South Devon was absorbed by the Great Western Railway in 1876 he moved to the latter's Swindon works. There he rose by successive promotions to become Works Manager in 1896, and in 1897 Chief Assistant to William Dean, who was Locomotive Carriage and Wagon Superintendent, in which capacity Churchward was allowed extensive freedom of action. Churchward eventually succeeded Dean in 1902: his title changed to Chief Mechanical Engineer in 1916.

In locomotive design, Churchward adopted the flat-topped firebox invented by A.J.Belpaire of the Belgian State Railways and added a tapered barrel to improve circulation of water between the barrel and the firebox legs. He designed valves with a longer stroke and a greater lap than usual, to achieve full opening to exhaust. Passenger-train weights had been increasing rapidly, and Churchward produced his first 4–6– 0 express locomotive in 1902. However, he was still developing the details—he had a flair for selecting good engineering practices—and to aid his development work Churchward installed at Swindon in 1904 a stationary testing plant for locomotives. This was the first of its kind in Britain and was based on the work of Professor W.F.M.Goss, who had installed the first such plant at Purdue University, USA, in 1891. For comparison with his own locomotives Churchward obtained from France three 4–4–2 compound locomotives of the type developed by A. de Glehn and G. du Bousquet. He decided against compounding, but he did perpetuate many of the details of the French locomotives, notably the divided drive between the first and second pairs of driving wheels, when he introduced his four-cylinder 4–6–0 (the Star class) in 1907. He built a lone 4–6–2, the Great Bear, in 1908: the wheel arrangement enabled it to have a wide firebox, but the type was not perpetuated because Welsh coal suited narrow grates and 4–6–0 locomotives were adequate for the traffic. After Churchward retired in 1921 his successor, C.B.Collett, was to enlarge the Star class into the Castle class and then the King class, both 4–6–0s, which lasted almost as long as steam locomotives survived in service. In Church ward's time, however, the Great Western Railway was the first in Britain to adopt six-coupled locomotives on a large scale for passenger trains in place of four-coupled locomotives. The 4–6–0 classes, however, were but the most celebrated of a whole range of standard locomotives of advanced design for all types of traffic and shared between them many standardized components, particularly boilers, cylinders and valve gear.

George Stephenson was the son of the fireman of the pumping engine at Wylam colliery, and horses drew wagons of coal along the wooden rails of the Wylam wagonway past the house in which he was born and spent his earliest childhood. While still a child he worked as a cowherd, but soon moved to working at coal pits. At 17 years of age he showed sufficient mechanical talent to be placed in charge of a new pumping engine, and had already achieved a job more responsible than that of his father. Despite his position he was still illiterate, although he subsequently learned to read and write. He was largely self-educated.

In 1801 he was appointed Brakesman of the winding engine at Black Callerton pit, with responsibility for lowering the miners safely to their work. Then, about two years later, he became Brakesman of a new winding engine erected by Robert Hawthorn at Willington Quay on the Tyne. Returning collier brigs discharged ballast into wagons and the engine drew the wagons up an inclined plane to the top of "Ballast Hill" for their contents to be tipped; this was one of the earliest applications of steam power to transport, other than experimentally.

In 1804 Stephenson moved to West Moor pit, Killingworth, again as Brakesman. In 1811 he demonstrated his mechanical skill by successfully modifying a new and unsatisfactory atmospheric engine, a task that had defeated the efforts of others, to enable it to pump a drowned pit clear of water. The following year he was appointed Enginewright at Killingworth, in charge of the machinery in all the collieries of the "Grand Allies", the prominent coal-owning families of Wortley, Liddell and Bowes, with authorization also to work for others. He built many stationary engines and he closely examined locomotives of John Blenkinsop's type on the Kenton \& Coxlodge wagonway, as well as those of William Hedley at Wylam.

It was in 1813 that Sir Thomas Liddell requested George Stephenson to build a steam locomotive for the Killingworth wagonway: Blucher made its first trial run on 25 July 1814 and was based on Blenkinsop's locomotives, although it lacked their rack-and-pinion drive. George Stephenson is credited with building the first locomotive both to run on edge rails and be driven by adhesion, an arrangement that has been the conventional one ever since. Yet Blucher was far from perfect and over the next few years, while other engineers ignored the steam locomotive, Stephenson built a succession of them, each an improvement on the last.

During this period many lives were lost in coalmines from explosions of gas ignited by miners' lamps. By observation and experiment (sometimes at great personal risk) Stephenson invented a satisfactory safety lamp, working independently of the noted scientist Sir Humphry Davy who also invented such a lamp around the same time.

In 1817 George Stephenson designed his first locomotive for an outside customer, the Kilmarnock \& Troon Railway, and in 1819 he laid out the Hetton Colliery Railway in County Durham, for which his brother Robert was Resident Engineer. This was the first railway to be worked entirely without animal traction: it used inclined planes with stationary engines, self-acting inclined planes powered by gravity, and locomotives.

On 19 April 1821 Stephenson was introduced to Edward Pease, one of the main promoters of the Stockton \& Darlington Railway (S \& DR), which by coincidence received its Act of Parliament the same day. George Stephenson carried out a further survey, to improve the proposed line, and in this he was assisted by his 18-year-old son, Robert Stephenson, whom he had ensured received the theoretical education which he himself lacked. It is doubtful whether either could have succeeded without the other; together they were to make the steam railway practicable.

At George Stephenson's instance, much of the S \& DR was laid with wrought-iron rails recently developed by John Birkinshaw at Bedlington Ironworks, Morpeth. These were longer than cast-iron rails and were not brittle: they made a track well suited for locomotives. In June 1823 George and Robert Stephenson, with other partners, founded a firm in Newcastle upon Tyne to build locomotives and rolling stock and to do general engineering work: after its Managing Partner, the firm was called Robert Stephenson \& Co.

In 1824 the promoters of the Liverpool \& Manchester Railway (L \& MR) invited George Stephenson to resurvey their proposed line in order to reduce opposition to it. William James, a wealthy land agent who had become a visionary protagonist of a national railway network and had seen Stephenson's locomotives at Killingworth, had promoted the L \& MR with some merchants of Liverpool and had carried out the first survey; however, he overreached himself in business and, shortly after the invitation to Stephenson, became bankrupt. In his own survey, however, George Stephenson lacked the assistance of his son Robert, who had left for South America, and he delegated much of the detailed work to incompetent assistants. During a devastating Parliamentary examination in the spring of 1825, much of his survey was shown to be seriously inaccurate and the L \& MR's application for an Act of Parliament was refused. The railway's promoters discharged Stephenson and had their line surveyed yet again, by C.B. Vignoles.

The Stockton \& Darlington Railway was, however, triumphantly opened in the presence of vast crowds in September 1825, with Stephenson himself driving the locomotive Locomotion, which had been built at Robert Stephenson \& Co.'s Newcastle works. Once the railway was at work, horse-drawn and gravity-powered traffic shared the line with locomotives: in 1828 Stephenson invented the horse dandy, a wagon at the back of a train in which a horse could travel over the gravity-operated stretches, instead of trotting behind.

Meanwhile, in May 1826, the Liverpool \& Manchester Railway had successfully obtained its Act of Parliament. Stephenson was appointed Engineer in June, and since he and Vignoles proved incompatible the latter left early in 1827. The railway was built by Stephenson and his staff, using direct labour. A considerable controversy arose c. 1828 over the motive power to be used: the traffic anticipated was too great for horses, but the performance of the reciprocal system of cable haulage developed by Benjamin Thompson appeared in many respects superior to that of contemporary locomotives. The company instituted a prize competition for a better locomotive and the Rainhill Trials were held in October 1829.

Robert Stephenson had been working on improved locomotive designs since his return from America in 1827, but it was the L \& MR's Treasurer, Henry Booth, who suggested the multi-tubular boiler to George Stephenson. This was incorporated into a locomotive built by Robert Stephenson for the trials: Rocket was entered by the three men in partnership. The other principal entrants were Novelty, entered by John Braithwaite and John Ericsson, and Sans Pareil, entered by Timothy Hackworth, but only Rocket, driven by George Stephenson, met all the organizers' demands; indeed, it far surpassed them and demonstrated the practicability of the long-distance steam railway. With the opening of the Liverpool \& Manchester Railway in 1830, the age of railways began.

Stephenson was active in many aspects. He advised on the construction of the Belgian State Railway, of which the Brussels-Malines section, opened in 1835, was the first all-steam railway on the European continent. In England, proposals to link the L \& MR with the Midlands had culminated in an Act of Parliament for the Grand Junction Railway in 1833: this was to run from Warrington, which was already linked to the L \& MR, to Birmingham. George Stephenson had been in charge of the surveys, and for the railway's construction he and J.U. Rastrick were initially Principal Engineers, with Stephenson's former pupil Joseph Locke under them; by 1835 both Stephenson and Rastrick had withdrawn and Locke was Engineer-in-Chief. Stephenson remained much in demand elsewhere: he was particularly associated with the construction of the North Midland Railway (Derby to Leeds) and related lines. He was active in many other places and carried out, for instance, preliminary surveys for the Chester \& Holyhead and Newcastle \& Berwick Railways, which were important links in the lines of communication between London and, respectively, Dublin and Edinburgh.

He eventually retired to Tapton House, Chesterfield, overlooking the North Midland. A man who was self-made (with great success) against colossal odds, he was ever reluctant, regrettably, to give others their due credit, although in retirement, immensely wealthy and full of honour, he was still able to mingle with people of all ranks.
