Long Boiler Locomotive
The Long Boiler locomotive was the object of a patent by Robert Stephenson and the name became synonymous with the pattern. Its defining feature is that the firebox is placed ''behind'' the rearmost driving axle. This gives a long boiler barrel, with long fire-tubes. There is thus a generous heating surface area, giving a boiler that is both powerful and efficient. It is generally perceived that it arose out of attempts to match the power of broad gauge locomotives within the limitations of the standard gauge of Stephenson railways. However, the patent originally arose from a problem which became apparent as trains travelled longer distances, specifically on the North Midland Railway in England around 1841, where fire tubes and smokeboxes were becoming destroyed by the heat. Experiments Experiments at the North Midland's Derby Works showed temperatures as high as , determined by placing a small cup of zinc within the smokebox beneath the chimney. Stephenson extended the boiler, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A No
A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish it fro ...

London And North Western Passenger Locomotive - Circa 1852 Illustration
London is the capital and largest city of England and the United Kingdom, with a population of just under 9 million. It stands on the River Thames in south-east England at the head of a estuary down to the North Sea, and has been a major settlement for two millennia. The City of London, its ancient core and financial centre, was founded by the Romans as ''Londinium'' and retains its medieval boundaries.See also: Independent city § National capitals The City of Westminster, to the west of the City of London, has for centuries hosted the national government and parliament. Since the 19th century, the name "London" has also referred to the metropolis around this core, historically split between the counties of Middlesex, Essex, Surrey, Kent, and Hertfordshire, which largely comprises Greater London, governed by the Greater London Authority.The Greater London Authority consists of the Mayor of London and the London Assembly. The London Mayor is distinguished from the Lord M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Driving Wheel
On a steam locomotive, a driving wheel is a powered wheel which is driven by the locomotive's pistons (or turbine, in the case of a steam turbine locomotive). On a conventional, non-articulated locomotive, the driving wheels are all coupled together with side rods (also known as coupling rods); normally one pair is directly driven by the main rod (or connecting rod) which is connected to the end of the piston rod; power is transmitted to the others through the side rods. On diesel and electric locomotives, the driving wheels may be directly driven by the traction motors. Coupling rods are not usually used, and it is quite common for each axle to have its own motor. Jackshaft drive and coupling rods were used in the past (e.g. in the Swiss Crocodile locomotive) but their use is now confined to shunting locomotives. On an articulated locomotive or a duplex locomotive, driving wheels are grouped into sets which are linked together within the set. Diameter Driving wheels ...

Crampton Locomotive
A Crampton locomotive is a type of steam locomotive designed by Thomas Russell Crampton and built by various firms from 1846. The main British builders were Tulk and Ley and Robert Stephenson and Company. Notable features were a low boiler and large driving wheels. The crux of the Crampton patent was that the single driving axle was placed behind the firebox, so that the driving wheels could be very large. This helped to give this design a low centre of gravity, so that it did not require a very broad-gauge track to travel safely at high speeds. Its wheel arrangement was usually or . Design variations Because the single driving axle was behind the firebox, Crampton locomotives usually had outside cylinders. However, some inside cylinder versions were built using indirect drive, then known as a ''jackshaft''. The inside cylinders drove a crankshaft located in front of the firebox and the crankshaft was connected to the driving wheels by outside rods. Some long-wheelbase s we ...

Thomas Russell Crampton
Thomas Russell Crampton, MICE, MIMechE (6 August 1816 – 19 April 1888) was an English engineer born at Broadstairs, Kent, and trained on Brunel's Great Western Railway. He is best known for designing the Crampton locomotive but had many engineering interests including the electric telegraph and the Channel Tunnel for which he designed a boring machine. His locomotives had much better success in France, Germany and Italy than they did in the UK. Personal life Born to John and Mary Crampton of Prospect Cottage (in what is now Dickens Walk), Broadstairs, on 6 August 1816, Crampton was the son of a plumber and architect. He was educated privately. Crampton married Louisa Martha Hall, who was a singer and a friend of Jenny Lind, on 25 February 1841. They had 8 children, six boys and two girls. The eldest girl, Ada Sarah, died aged 4 on 16 February 1857. and Crampton gifted a stained glass window in St. Peter's church, Broadstairs in her memory. Their youngest daughter, Louisa, wa ...

Jenny Lind Locomotive
Jenny Lind was the first of a class of ten steam locomotives built in 1847 for the London, Brighton and South Coast Railway (LB&SCR) by E. B. Wilson and Company of Leeds, named after Jenny Lind, who was a famous Swedish opera singer of the period. The general design proved to be so successful that the manufacturers adopted it for use on other railways, and it became the first mass-produced locomotive type. The "Jenny Lind" type was also widely copied during the late 1840s and 1850s, and into the 1860s. History David Joy, the Chief Draughtsman of E. B. Wilson and Company, was asked to visit Brighton railway works to make tracings of the drawings of a locomotive designed by John Gray for the railway so that ten further examples could be built. However, before he had completed the task, Gray had been dismissed from his post of Locomotive Superintendent, and his successor Thomas Kirtley did not favour Gray's complicated horse-leg motion. As a result it was left to Joy and James F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London And Brighton Railway
The London and Brighton Railway (L&BR) was a railway company in England which was incorporated in 1837 and survived until 1846. Its railway ran from a junction with the London and Croydon Railway (L&CR) at Norwood – which gives it access from London Bridge, just south of the River Thames in central London. It ran from Norwood to the South Coast at Brighton, together with a branch to Shoreham-by-Sea. Background During the English Regency, and particularly after the Napoleonic Wars, Brighton rapidly became a fashionable social resort, with more than 100,000 passengers being carried there each year by coach. Early schemes A proposal by William James in 1823 to connect London "with the ports of Shoreham (Brighton), Rochester (Chatham) and Portsmouth by a line of Engine Railroad" was largely ignored. However, about 1825 a company called The Surrey, Sussex, Hants, Wilts & Somerset Railway employed John Rennie to survey a route to Brighton, but again the proposal came to nothing. ...

John Gray (locomotive Engineer)
John Gray was an early English steam locomotive engineer who introduced several innovations in locomotive design during the 1830s and 1840s. John Gray's origins were thought to be unknown but he appears to have originated from Newcastle. John Gray was born 29 August 1810 in Newcastle upon Tyne, Northumberland, England. Career Innovations In 1838 he was working for the Liverpool and Manchester Railway where he was the first engineer to use the balanced slide valve on locomotives, and later applied a form of expansion gear. In 1840 he was appointed locomotive superintendent of the Hull and Selby Railway where he became the first locomotive engineer to use long-travel valve motion. Locomotive superintendent In 1845 he was appointed locomotive superintendent of the Croydon Dover and Brighton Joint Committee, which then operated the pooled locomotive fleets of the London and Croydon Railway, the South Eastern Railway and the London and Brighton Railway. On the dissolution of this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NER 1001 Class
The North Eastern Railway (NER) 1001 Class was a class of long-boiler 0-6-0 steam locomotive designed by William Bouch. Technical data A NER 1001 class locomotive weighed about , with a wheelbase of and diameter driven wheels. Its diameter boiler produced over of tractive effort at . History The "long boiler" design dated back to a Stephenson design of 1842. At that time there was a controversy about keeping the centre of gravity low. Another point of view was espoused by John Gray who set out to improve efficiency and increase the pressure in shorter boilers using single drivers instead of coupled wheels. His ideas led to the design of the highly successful Jenny Lind locomotive. The long boiler design with coupled wheels continued for slower heavier work. A total of 192 NER 1001 class locomotives were built from 1852 by a number of private manufacturers, as well as the NER's own works at Darlington and Shildon. The small size of the firebox would seem remarkable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Rail Transport In Great Britain 1830–1922
The history of rail transport in Great Britain 1830–1922 covers the period between the opening of the Liverpool and Manchester Railway (L&MR), and the Grouping, the amalgamation of almost all of Britain's many railway companies into the Big Four by the Railways Act 1921. The 1830s As Manchester had grown on cotton spinning, so Leeds had a growing trade in weaving. The Pennines restricted canal development, so the railway provided a realistic alternative, especially with the growth in coal usage from the mines in the North East and Yorkshire. A number of lines were approved in the area, such as the Leeds and Selby Railway, in 1830, which would link the former to the port of Hull, via the River Ouse. While the L&MR had not ousted the Lancashire canal system from the transport of goods, there was an unexpected enthusiasm for passenger travel. The financial success of these lines was beyond all expectations, and interests in London and Birmingham soon planned to build li ...

4-2-0
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of four leading wheels on two axles, two powered driving wheels on one axle and no trailing wheels. This type of locomotive is often called a Jervis type, the name of the original designer. Overview The wheel arrangement type was common on United States railroads from the 1830s through the 1850s. The first to be built was the ''Experiment'', later named ''Brother Jonathan'', for the Mohawk and Hudson Railroad in 1832. It was built by the West Point Foundry based on a design by John B. Jervis. Having little else to reference, the manufacturers patterned the boiler and valve gear after locomotives built by Robert Stephenson of England. A few examples of Stephenson locomotives were already in operation in America, so engineers did not have to travel too far to get their initial ideas. In England, the was developed around 1840 from the 2-2-2 design of Stephenson's first Long ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
