Answer the following question: Information:  - William Bouch ( / bat / ; 1813 -- 1876 ) is famous for the steam locomotives he designed for the Stockton and Darlington Railway . In 1860 , Bouch designed the first British standard gauge locomotives to use a 4 - 4 - 0 wheel layout which had earlier become popular in the United States .  - On a steam locomotive, a trailing wheel or trailing axle is generally an unpowered wheel or axle (wheelset) located behind the driving wheels. The axle of the trailing wheels is usually located in a trailing truck. On some large locomotives, a booster engine was mounted on the trailing truck to provide extra tractive effort when starting a heavy train and at low speeds on gradients.  - George Stephenson (9 June 1781  12 August 1848) was an English civil engineer and mechanical engineer who built the first public inter-city railway line in the world to use steam locomotives, the Liverpool and Manchester Railway which opened in 1830. Renowned as the "Father of Railways", the Victorians considered him a great example of diligent application and thirst for improvement, with self-help advocate Samuel Smiles particularly praising his achievements. His rail gauge of , sometimes called "Stephenson gauge", is the standard gauge by name and by convention for most of the world's railways.  - 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.  - Shildon is a town in County Durham, in England. The population taken at the 2011 Census was 9,976. It is situated south east of Bishop Auckland, north of Darlington, from Durham, from Sunderland and from Newcastle upon Tyne. Shildon is part of the Bishop Auckland parliamentary constituency, which has been represented since 2005 by Helen Goodman MP for the Labour Party.  - The Whyte notation for classifying steam locomotives by wheel arrangement was devised by Frederick Methvan Whyte, and came into use in the early twentieth century following a December 1900 editorial in "American Engineer and Railroad Journal". The notation counts the number of leading wheels, then the number of driving wheels, and finally the number of trailing wheels, groups of numbers being separated by dashes. Other classification schemes, like UIC classification and the French, Turkish and Swiss systems for steam locomotives, count axles rather than wheels.  - Middlesbrough is a large industrial town on the south bank of the River Tees in North East England, founded in 1830. The local council, a unitary authority, is Middlesbrough Borough Council. In 2011 it had a total resident population of 138,400 for the borough and 174,700 for the wider Middlesbrough built-up area subdivision, which itself is part of the larger built-up area of Teesside and had an overall population of 376,333 at the 2011 census.  - The standard gauge (also Stephenson gauge after George Stephenson, International gauge, or normal gauge) is a widely used railway track gauge. Approximately 55% of the lines in the world are this gauge. All high-speed rail lines (except those in Russia, Uzbekistan, and Finland) are standard gauge. The distance between the inside edges of the rails is defined to be (except in the United States, where it is still defined in Imperial and US customary units as ). It is also called the UIC gauge or UIC track gauge, the European gauge in the EU and Russia, or uniform gauge in Queensland, Australia.  - Stockton-on-Tees is a market town in the ceremonial county of County Durham, North East England. It is the major settlement in the borough of Stockton-on-Tees. The town sits within the Tees Valley region of the North East of England, and the wider borough had a population of 191,000 in 2011 estimates.  - Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of two leading wheels on one axle, four powered and coupled driving wheels on two axles and no trailing wheels. The wheel arrangement is known as a Porter.  - Under the Whyte notation for the classification of steam locomotives by wheel arrangement, represents the arrangement of four leading wheels on two axles, usually in a leading bogie, four powered and coupled driving wheels on two axles, and no trailing wheels. Almost every major railroad that operated in North America in the first half of the 19th century owned and operated locomotives of this type. Due to the large number of the type that were produced and used in the United States, the is most commonly known as the American type, but the type subsequently also became popular in the United Kingdom, where large numbers were produced. Overview. The first use of the name "American" to describe locomotives of this wheel arrangement was made by "Railroad Gazette" in April 1872. Prior to that, this wheel arrangement was known as a "standard" or "eight-wheeler". This locomotive type was so successful on railroads in the United States of America that many earlier 4-2-0 and 2-4-0 locomotives were rebuilt as 4-4-0s by the middle of the 19th century.  - The Stockton and Darlington Railway (S&DR) was a railway company that operated in north-east England from 1825 to 1863. The world's first public railway to use steam locomotives, its first line connected collieries near Shildon with Stockton-on-Tees and Darlington, and was officially opened on 27 September 1825. The movement of coal to ships rapidly became a lucrative business, and the line was soon extended to a new port and town at Middlesbrough. While coal waggons were hauled by steam locomotives from the start, passengers were carried in coaches drawn by horses until carriages hauled by steam locomotives were introduced in 1833.
