GWR 6400 Class
The Great Western Railway (GWR) 6400 Class is a class of 0-6-0 pannier tank steam locomotive introduced by Charles Collett in 1932. All 40 examples were 'auto-fitted' – equipped with the remote-control equipment needed for working GWR Autotrain, autotrains. The 1936 GWR 7400 Class was a similar class, without the autotrain apparatus, but with a higher boiler pressure of 180 psi, providing a small but useful increase in power. An initial build of 30 in 1936-1937 was added to by British Railways in two batches each of ten locos in 1948 and 1950. These were destined for a short life, the briefest being only nine years. A minor visual difference between the 5400 and earlier 6400, and the later series of 6400, with the 7400 classes was at the join between cab and bunker. The 5400 and early 6400 had an arc whereas the later 6400 and the 7400 class was straight. The early locos also had a lip at the leading edge of the cab roof, whereas the later locos had a plain corner edge. Both ...

Aberdare Low Level Railway Station
Aberdare Low Level railway station served the town of Aberdare in Wales. Opened by the Taff Vale Railway, it became part of the Great Western Railway during the Grouping of 1923. Passing to the Western Region of British Railways on nationalisation in 1948, it was then closed by the British Railways Board in 1964 when the passengers service from was withdrawn as a result of the Beeching Axe. The site today Aberdare is now served by Aberdare railway station, a new station opened on the site of the former high level station in 1988. The station here was demolished after the line through it closed in 1973; coal traffic from Tower Colliery at Hirwaun was then re-routed over a new connection onto the former Vale of Neath Railway line near to allow for the removal of the busy level crossing A level crossing is an intersection where a railway line crosses a road, Trail, path, or (in rare situations) airport runway, at the same level, as opposed to the railway line cross ...

Lostwithiel And Fowey Railway
The Lostwithiel and Fowey Railway opened in 1869 as a broad gauge railway linking the port of Fowey in Cornwall with the Cornish Main Line at Lostwithiel. Its main traffic was china clay. The company ran into financial difficulties and closed in 1880, but the line was purchased by the Cornwall Minerals Railway and reopened in 1895. A passenger service operated, but it was withdrawn in 1965, and the line reverted to the conveyance of china clay; it remains open for that traffic at the present day. Chronology * 1862 Lostwithiel and Fowey Railway Act * 1869 Line opened * 1874 Cornwall Minerals Railway opens from Par to Fowey * 1880 Service suspended * 1892 Lostwithiel and Fowey Railway Company dissolved * 1895 Reopened by Cornwall Minerals Railway * 1968 Par to Fowey line closed History Promoters of an independent company conducted negotiations with the Cornwall Railway in 1861, regarding the construction of a branch line from that railway at Lostwithiel to a location at Caffa ...

Laira Traction & Rolling Stock Maintenance Depot
Laira T&RSMD is a railway traction and rolling stock maintenance depot situated in Plymouth, Devon, England. The depot is operated by Great Western Railway and is mainly concerned with the overhaul and daily servicing of their fleet of High Speed Trains and also the DMUs used on local services. The depot code "LA" is used to identify rolling stock based there. After sixty years as a steam depot, servicing locomotives used on the Exeter to Plymouth line that runs past the shed as well as local lines, diesels started to arrive in 1958. A diesel depot opened in 1962 and was expanded in 1981 to accommodate the High Speed Trains. History Steam shed Laira was the location of the temporary terminus of the South Devon Railway from 5 May 1848 when a small engine shed would have been provided. With the completion of the line to Plymouth Millbay railway station on 2 April 1849 a new shed was provided there and the facilities at Laira dismantled, although it remained a junction for ...

Gloucestershire And Warwickshire Railway
The Gloucestershire Warwickshire Steam Railway (GWR, GWSR or Gloucs-Warks Steam Railway) is a volunteer-run heritage railway which runs along the Gloucestershire/Worcestershire border of the Cotswolds, England. The GWSR has restored and reopened around of track, operating between and . The most recent extension to Broadway (completed in 2018) involved the company raising £1.38 million. The 28 mile round trip on steam and heritage diesel trains follows part of the route of the former Great Western main line from Birmingham to Cheltenham. The GWSR has a long-term aim of extending a further from Broadway to the national rail network at (where one half of an island platform has since been partly rebuilt for future use). Overview The line was originally part of the Great Western Railway's Cheltenham– Stratford-upon-Avon–Birmingham line, known as the Honeybourne Line, built in 1900–1906, and runs through the Cotswold towns of Winchcombe and Bishop's Cleeve.

GWR Autocoach
The GWR Autocoach (or auto-trailer) is a type of coach that was used by the Great Western Railway for push-pull trains powered by a steam locomotive. The distinguishing design feature of an autocoach is the driving cab at one end, allowing the driver to control the train without needing to be located in the cab of the steam locomotive. This eliminates the need to run the engine round to the other end of the coach at the end of each journey. When one or more autocoaches are connected to a suitably equipped steam locomotive, the combination is known as an auto-train, or, historically, a railmotor train. A steam locomotive provided with the equipment to be used as an autotrain is said to be auto-fitted. The autocoach is the forerunner of the driving trailer used with push–pull trains. Design features A locomotive fitted with additional control equipment is used to power the autotrain. When running 'autocoach first', the regulator is operated by a linkage to a rotating shaft ...

Tavistock, Devon
Tavistock ( ) is an ancient stannary and market town within West Devon, England. It is situated on the River Tavy from which its name derives. At the 2011 census the three electoral wards (North, South and South West) had a population of 13,028. It traces its recorded history back to at least 961 when Tavistock Abbey, whose ruins lie in the centre of the town, was founded. Its most famous son is Sir Francis Drake. History Middle Ages The area around Tavistock (formerly Tavistoke), where the River Tavy runs wide and shallow allowing it to be easily crossed, and near the secure high ground of Dartmoor, was inhabited long before historical records. The surrounding area is littered with archaeological remains from the Bronze and Iron Ages and it is believed a hamlet existed on the site of the present town long before the town's official history began, with the founding of the Abbey. The abbey of Saint Mary and Saint Rumon was founded in 961 by Ordgar, Earl of Devon. After destruct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Multiple Unit
A diesel multiple unit or DMU is a multiple-unit train powered by on-board diesel engines. A DMU requires no separate locomotive, as the engines are incorporated into one or more of the carriages. Diesel-powered single-unit railcars are also generally classed as DMUs. Diesel-powered units may be further classified by their transmission type: diesel–mechanical DMMU, diesel–hydraulic DHMU, or diesel–electric DEMU. Design The diesel engine may be located above the frame in an engine bay or under the floor. Driving controls can be at both ends, on one end, or in a separate car. Types by transmission DMUs are usually classified by the method of transmitting motive power to their wheels. Diesel–mechanical In a diesel–mechanical multiple unit (DMMU), the rotating energy of the engine is transmitted via a gearbox and driveshaft directly to the wheels of the train, like a car. The transmissions can be shifted manually by the driver, as in the great majority of first-gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Devon
Devon ( , historically known as Devonshire , ) is a ceremonial and non-metropolitan county in South West England. The most populous settlement in Devon is the city of Plymouth, followed by Devon's county town, the city of Exeter. Devon is a coastal county with cliffs and sandy beaches. Home to the largest open space in southern England, Dartmoor (), the county is predominately rural and has a relatively low population density for an English county. The county is bordered by Somerset to the north east, Dorset to the east, and Cornwall to the west. The county is split into the non-metropolitan districts of East Devon, Mid Devon, North Devon, South Hams, Teignbridge, Torridge, West Devon, Exeter, and the unitary authority areas of Plymouth, and Torbay. Combined as a ceremonial county, Devon's area is and its population is about 1.2 million. Devon derives its name from Dumnonia (the shift from ''m'' to ''v'' is a typical Celtic consonant shift).

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 website, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cylinder (locomotive)
The cylinder is the power-producing element of the steam engine powering a steam locomotive. The cylinder is made pressure-tight with end covers and a piston; a valve distributes the steam to the ends of the cylinder. Cylinders were cast in iron and later made of steel. The cylinder casting includes other features such as (in the case of the early Rocket locomotive) valve ports and mounting feet. The last big American locomotives incorporated the cylinders as part of huge one-piece steel castings that were the main frame of the locomotive. Renewable wearing surfaces were needed inside the cylinders and provided by cast-iron bushings. The way the valve controlled the steam entering and leaving the cylinder was known as steam distribution and shown by the shape of the indicator diagram. What happened to the steam inside the cylinder was assessed separately from what happened in the boiler and how much friction the moving machinery had to cope with. This assessment was known as "e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stroke (engine)
In the context of an internal combustion engine, the term stroke has the following related meanings: * A phase of the engine's cycle (e.g. compression stroke, exhaust stroke), during which the piston travels from top to bottom or vice versa. * The type of power cycle used by a piston engine (e.g. two-stroke engine, four-stroke engine). * "Stroke length", the distance travelled by the piston during each cycle. The stroke length––along with bore diameter––determines the engine's displacement. Phases in the power cycle Commonly used engine phases or strokes (i.e. those used in a four-stroke engine) are described below. Other types of engines can have very different phases. Induction-intake stroke The induction stroke is the first phase in a four-stroke (e.g. Otto cycle or Diesel cycle) engine. It involves the downward movement of the piston, creating a partial vacuum that draws a air-fuel mixture (or air alone, in the case of a direct injection engine) into the combus ...
