Orphaned as a child, Hamilton went to work for Southern Pacific Railroad in his teens, and then worked for several other companies. In his spare time he learned mathematics and physics from a retired professor. In 1911 he joined the White Motor Company, makers of road motor vehicles in Denver, Colorado, where he had gone to recuperate from malaria. He remained there until 1922, apart from an eighteenth-month break for war service.

Upon his return from war service, Hamilton found White selling petrol-engined railbuses with mechanical transmission, based on road vehicles, to railways. He noted that they were not robust enough and that the success of petrol railcars with electric transmission, built by General Electric since 1906, was limited as they were complex to drive and maintain. In 1922 Hamilton formed, and became President of, the Electro- Motive Engineering Corporation (later Electro-Motive Corporation) to design and produce petrol-electric rail cars. Needing an engine larger than those used in road vehicles, yet lighter and faster than marine engines, he approached the Win ton Engine Company to develop a suitable engine; in addition, General Electric provided electric transmission with a simplified control system. Using these components, Hamilton arranged for his petrol-electric railcars to be built by the St Louis Car Company, with the first being completed in 1924. It was the beginning of a highly successful series. Fuel costs were lower than for steam trains and initial costs were kept down by using standardized vehicles instead of designing for individual railways. Maintenance costs were minimized because Electro-Motive kept stocks of spare parts and supplied replacement units when necessary. As more powerful, 800 hp (600 kW) railcars were produced, railways tended to use them to haul trailer vehicles, although that practice reduced the fuel saving. By the end of the decade Electro-Motive needed engines more powerful still and therefore had to use cheap fuel. Diesel engines of the period, such as those that Winton had made for some years, were too heavy in relation to their power, and too slow and sluggish for rail use. Their fuel-injection system was erratic and insufficiently robust and Hamilton concluded that a separate injector was needed for each cylinder.

In 1930 Electro-Motive Corporation and Winton were acquired by General Motors in pursuance of their aim to develop a diesel engine suitable for rail traction, with the use of unit fuel injectors; Hamilton retained his position as President. At this time, industrial depression had combined with road and air competition to undermine railway-passenger business, and Ralph Budd, President of the Chicago, Burlington \& Quincy Railroad, thought that traffic could be recovered by way of high-speed, luxury motor trains; hence the Pioneer Zephyr was built for the Burlington. This comprised a 600 hp (450 kW), lightweight, two-stroke, diesel engine developed by General Motors (model 201 A), with electric transmission, that powered a streamlined train of three articulated coaches. This train demonstrated its powers on 26 May 1934 by running non-stop from Denver to Chicago, a distance of 1,015 miles (1,635 km), in 13 hours and 6 minutes, when the fastest steam schedule was 26 hours. Hamilton and Budd were among those on board the train, and it ushered in an era of high-speed diesel trains in the USA. By then Hamilton, with General Motors backing, was planning to use the lightweight engine to power diesel-electric locomotives. Their layout was derived not from steam locomotives, but from the standard American boxcar. The power plant was mounted within the body and powered the bogies, and driver's cabs were at each end. Two 900 hp (670 kW) engines were mounted in a single car to become an 1,800 hp (l,340 kW) locomotive, which could be operated in multiple by a single driver to form a 3,600 hp (2,680 kW) locomotive. To keep costs down, standard locomotives could be mass-produced rather than needing individual designs for each railway, as with steam locomotives. Two units of this type were completed in 1935 and sent on trial throughout much of the USA. They were able to match steam locomotive performance, with considerable economies: fuel costs alone were halved and there was much less wear on the track. In the same year, Electro-Motive began manufacturing diesel-electrie locomotives at La Grange, Illinois, with design modifications: the driver was placed high up above a projecting nose, which improved visibility and provided protection in the event of collision on unguarded level crossings; six-wheeled bogies were introduced, to reduce axle loading and improve stability. The first production passenger locomotives emerged from La Grange in 1937, and by early 1939 seventy units were in service. Meanwhile, improved engines had been developed and were being made at La Grange, and late in 1939 a prototype, four-unit, 5,400 hp (4,000 kW) diesel-electric locomotive for freight trains was produced and sent out on test from coast to coast; production versions appeared late in 1940. After an interval from 1941 to 1943, when Electro-Motive produced diesel engines for military and naval use, locomotive production resumed in quantity in 1944, and within a few years diesel power replaced steam on most railways in the USA.

Hal Hamilton remained President of Electro-Motive Corporation until 1942, when it became a division of General Motors, of which he became Vice-President.

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.

Lartigue worked as a civil engineer in Algeria and while there invented a simple monorail for industrial or agricultural use. It comprised a single rail carried on trestles; vehicles comprised a single wheel with two tubs suspended either side, like panniers. These were pushed or pulled by hand or, occasionally, hauled by mule. Such lines were used in Algerian esparto-grass plantations.

In 1882 he patented a monorail system based on this arrangement, with important improvements: traction was to be mechanical; vehicles were to have two or four wheels and to be able to be coupled together; and the trestles were to have, on each side, a light guide rail upon which horizontal rollers beneath the vehicles would bear. Early in 1883 the Lartigue Railway Construction Company was formed in London and two experimental prototype monorails were subsequently demonstrated in public. One, at the Paris Agricultural Exhibition, had an electric locomotive that was built in two parts, one either side of the rail to maintain balance, hauling small wagons. The other prototype, in London, had a small, steam locomotive with two vertical boilers and was designed by Anatole Mallet. By now Lartigue had become associated with F.B. Behr. Behr was Managing Director of the construction company and of the Listowel \& Ballybunion Railway Company, which obtained an Act of Parliament in 1886 to built a Lartigue monorail railway in the South West of Ireland between those two places. Its further development and successful operation are described in the article on Behr in this volume.

A much less successful attempt to establish a Lartigue monorail railway took place in France, in the départment of Loire. In 1888 the council of the département agreed to a proposal put forward by Lartigue for a 10 1/2 mile (17 km) long monorail between the towns of Feurs and Panissières: the agreement was reached on the casting vote of the Chairman, a contact of Lartigue. A concession was granted to successive companies with which Lartigue was closely involved, but construction of the line was attended by muddle, delay and perhaps fraud, although it was completed sufficiently for trial trains to operate. The locomotive had two horizontal boilers, one either side of the track. But the inspectors of the department found deficiencies in the completeness and probable safety of the railway; when they did eventually agree to opening on a limited scale, the company claimed to have insufficient funds to do so unless monies owed by the department were paid. In the end the concession was forfeited and the line dismantled. More successful was an electrically operated Lartigue mineral line built at mines in the eastern Pyrenees.

It appears to have reused equipment from the electric demonstration line, with modifications, and included gradients as steep as 1 in 12. There was no generating station: descending trains generated the electricity to power ascending ones. This line is said to have operated for at least two years.

Gresley was the son of the Rector of Netherseale, Derbyshire; he was educated at Marlborough and by the age of 13 was skilled at making sketches of locomotives. In 1893 he became a pupil of F.W. Webb at Crewe works, London \& North Western Railway, and in 1898 he moved to Horwich works, Lancashire \& Yorkshire Railway, to gain drawing-office experience under J.A.F.Aspinall, subsequently becoming Foreman of the locomotive running sheds at Blackpool. In 1900 he transferred to the carriage and wagon department, and in 1904 he had risen to become its Assistant Superintendent. In 1905 he moved to the Great Northern Railway, becoming Superintendent of its carriage and wagon department at Doncaster under H.A. Ivatt. In 1906 he designed and produced a bogie luggage van with steel underframe, teak body, elliptical roof, bowed ends and buckeye couplings: this became the prototype for East Coast main-line coaches built over the next thirty-five years. In 1911 Gresley succeeded Ivatt as Locomotive, Carriage \& Wagon Superintendent. His first locomotive was a mixed-traffic 2–6–0, his next a 2–8–0 for freight. From 1915 he worked on the design of a 4–6–2 locomotive for express passenger traffic: as with Ivatt's 4 4 2s, the trailing axle would allow the wide firebox needed for Yorkshire coal. He also devised a means by which two sets of valve gear could operate the valves on a three-cylinder locomotive and applied it for the first time on a 2–8–0 built in 1918. The system was complex, but a later simplified form was used on all subsequent Gresley three-cylinder locomotives, including his first 4–6–2 which appeared in 1922. In 1921, Gresley introduced the first British restaurant car with electric cooking facilities.

With the grouping of 1923, the Great Northern Railway was absorbed into the London \& North Eastern Railway and Gresley was appointed Chief Mechanical Engineer. More 4–6– 2s were built, the first British class of such wheel arrangement. Modifications to their valve gear, along lines developed by G.J. Churchward, reduced their coal consumption sufficiently to enable them to run non-stop between London and Edinburgh. So that enginemen might change over en route, some of the locomotives were equipped with corridor tenders from 1928. The design was steadily improved in detail, and by comparison an experimental 4–6–4 with a watertube boiler that Gresley produced in 1929 showed no overall benefit. A successful high-powered 2–8–2 was built in 1934, following the introduction of third-class sleeping cars, to haul 500-ton passenger trains between Edinburgh and Aberdeen.

In 1932 the need to meet increasing road competition had resulted in the end of a long-standing agreement between East Coast and West Coast railways, that train journeys between London and Edinburgh by either route should be scheduled to take 8 1/4 hours. Seeking to accelerate train services, Gresley studied high-speed, diesel-electric railcars in Germany and petrol-electric railcars in France. He considered them for the London \& North Eastern Railway, but a test run by a train hauled by one of his 4–6–2s in 1934, which reached 108 mph (174 km/h), suggested that a steam train could better the railcar proposals while its accommodation would be more comfortable. To celebrate the Silver Jubilee of King George V, a high-speed, streamlined train between London and Newcastle upon Tyne was proposed, the first such train in Britain. An improved 4–6–2, the A4 class, was designed with modifications to ensure free running and an ample reserve of power up hill. Its streamlined outline included a wedge-shaped front which reduced wind resistance and helped to lift the exhaust dear of the cab windows at speed. The first locomotive of the class, named Silver Link, ran at an average speed of 100 mph (161 km/h) for 43 miles (69 km), with a maximum speed of 112 1/2 mph (181 km/h), on a seven-coach test train on 27 September 1935: the locomotive went into service hauling the Silver Jubilee express single-handed (since others of the class had still to be completed) for the first three weeks, a round trip of 536 miles (863 km) daily, much of it at 90 mph (145 km/h), without any mechanical troubles at all. Coaches for the Silver Jubilee had teak-framed, steel-panelled bodies on all-steel, welded underframes; windows were double glazed; and there was a pressure ventilation/heating system. Comparable trains were introduced between London Kings Cross and Edinburgh in 1937 and to Leeds in 1938.

Gresley did not hesitate to incorporate outstanding features from elsewhere into his locomotive designs and was well aware of the work of André Chapelon in France. Four A4s built in 1938 were equipped with Kylchap twin blast-pipes and double chimneys to improve performance still further. The first of these to be completed, no. 4468, Mallard, on 3 July 1938 ran a test train at over 120 mph (193 km/h) for 2 miles (3.2 km) and momentarily achieved 126 mph (203 km/h), the world speed record for steam traction. J.Duddington was the driver and T.Bray the fireman. The use of high-speed trains came to an end with the Second World War. The A4s were then demonstrated to be powerful as well as fast: one was noted hauling a 730-ton, 22-coach train at an average speed exceeding 75 mph (120 km/h) over 30 miles (48 km). The war also halted electrification of the Manchester-Sheffield line, on the 1,500 volt DC overhead system; however, anticipating eventual resumption, Gresley had a prototype main-line Bo-Bo electric locomotive built in 1941. Sadly, Gresley died from a heart attack while still in office.

England trained with John Penn \& Sons, marine engine and boilermakers, and set up his own business at Hatcham Iron Works, South London, in about 1840. This was initially a general engineering business and made traversing screw jacks, which England had patented, but by 1850 it was building locomotives. One of these, Little England, a 2–2– 2T light locomotive owing much to the ideas of W.Bridges Adams, was exhibited at the Great Exhibition of 1851, and England then prospered, supplying many railways at home and abroad with small locomotives. In 1863 he built two exceptionally small 0–4–0 tank locomotives for the Festiniog Railway, which enabled the latter's Manager and Engineer C.E. Spooner to introduce steam traction on this line with its gauge of just under 2 ft (60 cm). England's works had a reputation for good workmanship, suggesting he inspired loyalty among his employees, yet he also displayed increasingly tyrannical behaviour towards them: the culmination was a disastrous strike in 1865 that resulted in the loss of a substantial order from the South Eastern Railway. From 1866 George England became associated with development of locomotives to the patent of Robert Fairlie, but in 1869 he retired due to ill health and leased his works to a partnership of his son (also called George England), Robert Fairlie and J.S.Fraser under the title of the Fairlie Engine \& Steam Carriage Company. However, George England junior died within a few months, locomotive production ceased in 1870 and the works was sold off two years later.
