GWR 633 Class
The GWR 633 Class were s designed by George Armstrong and built at the Wolverhampton railway works of the Great Western Railway between November 1871 and April 1872. These were always southern division locomotives but over the years some were fitted to work the metropolitan lines and played a large role in the transportation of goods from Acton to Smithfield. Unusually, they had side (not saddle) tanks, and inside frames, with wheels of in diameter and a wheelbase of . The weight was 34 tons 12 cwt. There were twelve locomotives, numbered 633–644.Smith, Martin, ''Steam on the Underground'', Ian Allan Publishing 1994, p.22, Modifications Nos. 643 and 644 were fitted with condensing apparatus when built, for working on the Metropolitan Railway Widened Lines and this was added to some others in the 1890s. These were the first size-coupled engines to be accepted for the widened lines. From 1887 they were reboilered with Dean pattern boilers and the wheels were enlarged by ...

Belpaire Firebox
The Belpaire firebox is a type of firebox used on steam locomotives. It was invented by Alfred Belpaire of Belgium in 1864. Today it generally refers to the shape of the outer shell of the firebox which is approximately flat at the top and square in cross-section, indicated by the longitudinal ridges on the top sides. However, it is the similar square cross-section inner firebox which provides the main advantages of this design i.e. it has a greater surface area at the top of the firebox where the heat is greatest, improving heat transfer and steam production, compared with a round-top shape. The flat firebox top would make supporting it against pressure more difficult (e.g. by means of girders, or stays) compared to a round-top. However, the use of a similarly shaped square outer boiler shell allows simpler perpendicular stays to be used between the shells. The Belpaire outer firebox is, nevertheless, more complicated and expensive to manufacture than a round-top version. D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Locomotives Introduced In 1871
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facilit ...

Railway Correspondence And Travel Society
The Railway Correspondence and Travel Society (RCTS) is a national society founded in Cheltenham, England in 1928 to bring together those interested in rail transport and locomotives. Since 1929 the Society has published a regular journal ''The Railway Observer'' which records the current railway scene. It also has regional branches which organise meetings and trips to places of interest and an archive & library. It has published definitive multi-volume locomotive histories of the Great Western, Southern and London & North Eastern Railways, and has in progress similar works on the London, Midland & Scottish Railway and British Railways standard steam locomotives. It also has published many other historical railway books since the mid-1950s. On 2 November 2016, the RCTS become a Charitable Incorporated Organisation (CIO), registered number 1169995. Its new Archive and Library (located within the former station-master's house at Leatherhead station) was opened on 6 Octobe ...

South Wales
South Wales ( cy, De Cymru) is a loosely defined region of Wales bordered by England to the east and mid Wales to the north. Generally considered to include the historic counties of Glamorgan and Monmouthshire, south Wales extends westwards to include Carmarthenshire and Pembrokeshire. In the western extent, from Swansea westwards, local people would probably recognise that they lived in both south Wales and west Wales. The Brecon Beacons National Park covers about a third of south Wales, containing Pen y Fan, the highest British mountain south of Cadair Idris in Snowdonia. A point of some discussion is whether the first element of the name should be capitalised: 'south Wales' or 'South Wales'. As the name is a geographical expression rather than a specific area with well-defined borders, style guides such as those of the BBC and ''The Guardian'' use the form 'south Wales'. In a more authoritative style guide, the Welsh Government, in their international gateway w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neath
Neath (; cy, Castell-nedd) is a market town and community situated in the Neath Port Talbot County Borough, Wales. The town had a population of 50,658 in 2011. The community of the parish of Neath had a population of 19,258 in 2011. Historically in Glamorgan, the town is located on the River Neath, east-northeast of Swansea. Etymology The town's English name ultimately derives from "" the original Welsh name for the River Neath and is known to be Celtic or Pre-Celtic. A meaning of 'shining' or 'brilliant' has been suggested, as has a link to the older Indo-European root ' (simply meaning 'river'). As such, the town may share its etymology with the town of Stratton, Cornwall and the River Nidd in Northern England. History Roman fort The town is located at a ford of the River Neath and its strategic situation is evident by a number of Celtic hill forts, surrounding the town. The Romans also recognised the area's strategic importance and built an Auxiliary Fort o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Railway Tire
The steel wheel of a steam locomotive and other older types of rolling stock were usually fitted with a steel tire (American English) or tyre (in British English, Australian English and others) to provide a replaceable wearing element on a costly wheel. Installation Replacing a whole wheel because of a worn contact surface was expensive, so older types of railway wheels were fitted with a replaceable steel tire. The tire is a hoop of steel that is fitted around the steel wheel centre. The tire is machined with a shoulder on its outer face to locate it on the wheel centre, and a groove on the inside diameter of the flange face. The inside diameter of the tire is machined to be slightly less than the diameter of the wheel centre on which it is mounted, to give an interference fit. The tire is fitted by heating to a controlled temperature, avoiding overheating. This causes the tire to expand. The wheel centre, usually already mounted on the axle, is lowered into the tire which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Armstrong (engineer)
George Armstrong (5 April 1822 – 11 July 1901) was an English railway engineer. He was in charge of standard gauge steam locomotives for the Great Western Railway at Stafford Road Works, Wolverhampton, from 1864 to 1897. He was the younger brother of his colleague Joseph Armstrong, but thanks to the special requirements of the GWR at a time when it was split in two by the broad and standard gauges, the brothers were able to work largely independently of each other. George is best remembered for his 0-4-2 and 0-6-0 tank engines; these were long-lived, and even when life-expired they were replaced by Collett and Hawksworth with remarkably similar locomotives, the well-known 1400, 5700 and 1600 classes. Biography George Armstrong was born on 5 April 1822. His gravestone states that the place was Bewcastle, Cumberland, and this information is repeated by Marshall. However, Holcroft writes that the family went to Canada in 1817, not returning until 1824, and that consequent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
