8 Jervis, John Bloomfield
[br]b. 14 December 1795 Huntingdon, New York, USAd. 12 January 1885 Rome, New York, USA[br]American pioneer of civil engineering and locomotive design.[br]Jervis assisted in the survey and construction of the Erie Canal, and by 1827 was Chief Engineer of the Delaware \& Hudson Canal and, linked with it, the Carbondale Railroad. He instructed Horatio Allen to go to England to purchase locomotives in 1828, and the locomotive Stourbridge Lion, built by J.U. Rastrick, was placed on the railway in 1829. It was the first full-size locomotive to run in America, but the track proved too weak for it to be used regularly. In 1830 Jervis became Chief Engineer to the Mohawk \& Hudson Rail Road, which was the first railway in New York State and was opened the following year. In 1832 the 4–2–0 locomotive Experiment was built to his plans by West Point Foundry: it was the first locomotive to have a leading bogie or truck. Jervis was subsequently associated with many other extensive canals and railways and pioneered economic analysis of engineering problems to enable, for example, the best choice to be made between two possible routes for a railroad.[br]Bibliography1861, Railway Property, New York.Further ReadingJ.H.White Jr, 1979, A History of the American Locomotive-Its Development: 1830–1880, New York: Dover Publications Inc.J.K.Finch, 1931, "John Bloomfield Jervis, civil engineer", Transactions of the Newcomen Society, 11.PJGRBiographical history of technology > Jervis, John Bloomfield

12 Spooner, Charles Easton
[br]b. 1818 Maentwrog, Merioneth (now Gwynedd), Walesd. 18 November 1889 Portmadoc (now Porthmadog), Wales[br]English engineer, pioneer of narrow-gauge steam railways.[br]At the age of 16 Charles Spooner helped his father, James, to build the Festiniog Railway, a horse-and-gravity tramroad; they maintained an even gradient and kept costs down by following a sinuous course along Welsh mountainsides and using a very narrow gauge. This was probably originally 2 ft 1 in. (63.5 cm) from rail centre to rail centre; with the introduction of heavier, and therefore wider, rails the gauge between them was reduced and was eventually standardized at 1 ft 11 1/2 in (60 cm). After James Spooner's death in 1856 Charles Spooner became Manager and Engineer of the Festiniog Railway and sought to introduce steam locomotives. Widening the gauge was impracticable, but there was no precedent for operating a public railway of such narrow gauge by steam. Much of the design work for locomotives for the Festiniog Railway was the responsibility of C.M.Holland, and many possible types were considered: eventually, in 1863, two very small 0–4–0 tank locomotives, with tenders for coal, were built by George England.These locomotives were successful, after initial problems had been overcome, and a passenger train service was introduced in 1865 with equal success. The potential for economical operation offered by such a railway attracted widespread attention, the more so because it had been effectively illegal to build new passenger railways in Britain to other than standard gauge since the Gauge of Railways Act of 1846.Spooner progressively improved the track, alignment, signalling and rolling stock of the Festiniog Railway and developed it from a tramroad to a miniaturized main line. Increasing traffic led to the introduction in 1869 of the 0–4–4–0 double-Fairlie locomotive Little Wonder, built to the patent of Robert Fairlie. This proved more powerful than two 0–4–0s and impressive demonstrations were given to engineers from many parts of the world, leading to the widespread adoption of narrow-gauge railways. Spooner himself favoured a gauge of 2 ft 6 in. (76 cm) or 2 ft 9 in. (84 cm). Comparison of the economy of narrow gauges with the inconvenience of a break of gauge at junctions with wider gauges did, however, become a continuing controversy, which limited the adoption of narrow gauges in Britain.Bogie coaches had long been used in North America but were introduced to Britain by Spooner in 1872, when he had two such coaches built for the Festiniog Railway. Both of these and one of its original locomotives, though much rebuilt, remain in service.Spooner, despite some serious illnesses, remained Manager of the Festiniog Railway until his death.[br]Bibliography1869, jointly with G.A.Huddart, British patent no. 1,487 (improved fishplates). 1869, British patent no. 2,896 (rail-bending machinery).1871, Narrow Gauge Railways, E. \& F.N.Spon (includes his description of the Festiniog Railway, reports of locomotive trials and his proposals for narrow-gauge railways).Further ReadingJ.I.C.Boyd, 1975, The Festiniog Railway, Blandford: Oakwood Press; C.E.Lee, 1945, Narrow-Gauge Railways in North Wales, The Railway Publishing Co.

13 Sprague, Frank Julian
[br]b. 25 July 1857 Milford, Connecticut, USAd. 25 October 1934 New York, USA[br]American electrical engineer and inventor, a leading innovator in electric propulsion systems for urban transport.[br]Graduating from the United States Naval Academy, Annapolis, in 1878, Sprague served at sea and with various shore establishments. In 1883 he resigned from the Navy and obtained employment with the Edison Company; but being convinced that the use of electricity for motive power was as important as that for illumination, in 1884 he founded the Sprague Electric Railway and Motor Company. Sprague began to develop reliable and efficient motors in large sizes, marketing 15 hp (11 kW) examples by 1885. He devised the method of collecting current by using a wooden, spring-loaded rod to press a roller against the underside of an overhead wire. The installation by Sprague in 1888 of a street tramway on a large scale in Richmond, Virginia, was to become the prototype of the universally adopted trolley system with overhead conductor and the beginning of commercial electric traction. Following the success of the Richmond tramway the company equipped sixty-seven other railways before its merger with Edison General Electric in 1890. The Sprague traction motor supported on the axle of electric streetcars and flexibly mounted to the bogie set a pattern that was widely adopted for many years.Encouraged by successful experiments with multiple-sheave electric elevators, the Sprague Elevator Company was formed and installed the first set of high-speed passenger cars in 1893–4. These effectively displaced hydraulic elevators in larger buildings. From experience with control systems for these, he developed his system of multiple-unit control for electric trains, which other engineers had considered impracticable. In Sprague's system, a master controller situated in the driver's cab operated electrically at a distance the contactors and reversers which controlled the motors distributed down the train. After years of experiment, Sprague's multiple-unit control was put into use for the first time in 1898 by the Chicago South Side Elevated Railway: within fifteen years multiple-unit operation was used worldwide.[br]Principal Honours and DistinctionsPresident, American Institute of Electrical Engineers 1892–3.
