The Great Western main line
Great Western main line
is a main line railway in England, that runs westwards from London Paddington
London Paddington
to Bristol
Bristol
Temple Meads. Opened in 1841, it was the original route of the pre-1948 Great Western Railway
Railway
which was merged into the Western Region of British Railways and is now a part of the national rail system managed by Network Rail. The line is currently being electrified. It was electrified from Paddington to Heathrow Airport
Heathrow Airport
in the late 1990s. Work to electrify the remainder of the route started in 2011 with an initial aim to complete the work all the way to Bristol
Bristol
by 2016.[2] The programme however has been deferred with no end completion forecast because costs have tripled. The four sections deferred are: Didcot

History[edit] See also: Great Western Railway The line was built by the Great Western Railway
Railway
and engineered by Isambard Kingdom Brunel
Isambard Kingdom Brunel
as a dual track line using a wider 7 ft (2,134 mm) broad gauge and was opened in stages between 1838 and 1841. The final section, between Chippenham
Chippenham
and Bath, was opened on completion of the Box Tunnel
Box Tunnel
in June 1841.[5] The alignment was so level and straight it was nicknamed "Brunel's billiard table". It was supplemented with a third rail for dual gauge operation, allowing standard gauge 4 ft 8 1⁄2 in (1,435 mm) trains to also operate on the route, in stages between 1854 and 1875. Dual gauge

station area (May 1854). The broad gauge remained in use until 1892. Evidence of the original broad gauge can still be seen at many places where bridges are a wider than usual, or where tracks are ten feet apart instead of the usual six.[citation needed] The original dual tracks were widened to four in places, mainly in the east half, between 1877 and 1899: Paddington to Southall

and Swindon, and at Bristol.[citation needed] Following the Slough rail accident in 1900 when five passengers were killed, improved vacuum braking systems were used on locomotives and passenger rolling stock and Automatic Train Control (ATC) was introduced in 1908. Further widenings of the line took place between 1903 and 1910 and more widening work took place between 1931 and 1932.[6] At the outbreak of World War I
World War I
in 1914, the Great Western Railway
Railway
was taken into government control, as were most major railways in Britain and were reorganised after the war into the "big four" companies, of which the Great Western Railway
Railway
was one. The railways returned to direct government control during World War II
World War II
before being nationalised to form British Railways (BR) in 1948.[relevant? – discuss] The line speed was upgraded in the 1970s to support the introduction of the InterCity 125
InterCity 125
(HST).[7] In 1977 the Parliamentary Select Committee on Nationalised Industries recommended considering electrification of more of Britain's rail network, and by 1979 BR presented a range of options that included electrifying the line from Paddington to Swansea by 2000.[8] Under the 1979–90 Conservative governments that succeeded the 1976–79 Labour government, the proposal was not implemented. In August 2008 it was announced that a number of speed limits on the relief lines between Reading and London
London
had been raised, so that 86% of the line could be used at 90 miles per hour (140 km/h).[9] Heritage[edit] The route of the GWML includes dozens of listed buildings and structures, including tunnel portals, bridges and viaducts, stations, and associated hotels.[10] Part of the route passes through and contributes to the Georgian Architecture

three times, including on the famous Maidenhead Railway
Railway
Bridge. After Swindon, trains pass the Swindon
Swindon
Steam Railway Museum. From Wootton Bassett there are two different routes to Bristol, firstly via Box Tunnel
Box Tunnel
and secondly via Bristol
Bristol
Parkway. It is also possible to run via the Wessex Main Line, but this involves a reversal at Bradford Junction, so is only really suitable for multiple unit trains or via Reading to Bath via Newbury. Trains on the Great Western main line
Great Western main line
are sometimes diverted from Reading along the Reading to Taunton line, as far as Westbury, from where they can use the Wessex Main Line

trains continue to Pembroke Dock on weekends during the Summer season to connect with ferry services to Ireland. Infrastructure[edit] Between London
London
and Didcot
Didcot
there are four tracks, two for each direction. The main lines are mostly used by the faster trains and are on the south side of the route. The relief lines on the north side are used for slower services and those that need to call at all stations as only London
London
Paddington, Slough, Maidenhead, Twyford, Reading and Didcot
Didcot
Parkway stations have platforms on the main lines (although a few others have main line platforms that can be used in an emergency). Between Didcot
Didcot
and Royal Wootton Bassett
Royal Wootton Bassett
there are a series of passing loops lines to allow fast trains to overtake slower ones. This section is also signalled for bi-directional running on each line but this facility is usually only used during engineering working or when there is significant disruption to traffic in one direction.[15] The line is electrified between Paddington and Didcot
Didcot
Parkway using 25 kV AC overhead supply lines.[16] The line speed is 125 miles per hour (201 km/h).[17] The relief lines from Paddington to Didcot
Didcot
are limited to 90 miles per hour (140 km/h) as far as Reading, and then 100 miles per hour (160 km/h) to Didcot. Lower restrictions apply at various locations.[15] The line is one of two Network Rail-owned lines equipped with the Automatic Train Protection
Automatic Train Protection
(ATP) system, the other being the Chiltern Main Line.[18] Tunnels, viaducts and major bridges[edit] Major civil engineering structures on the Great Western main line include the following.[19]

Planned developments[edit] Main article: 21st-century modernisation of the Great Western main line Since 2011, the Great Western has been undergoing a £5 billion modernisation by Network Rail.[21] Reading railway station
Reading railway station
saw a major redevelopment with new platforms, a new entrance, footbridge and lifts; the work was completed a year ahead of schedule[22] in July 2014.[23][24] Electrification from Airport Junction to the west[edit] The Crossrail
Crossrail
project covered electrification of the line from Airport Junction to Maidenhead
Maidenhead
and, following a number of announcements and delays, the government announced in March 2011 that it would electrify the line between London
London
and Cardiff together with the section linking Bristol
Bristol
Parkway and Bristol
Bristol
Temple Meads.[25][26] In July 2012, the government announced that the final portion of the Great Western, from Cardiff to Swansea, would be electrified.[27] Following delays to the original plan, and a major escalation of costs, the Conservative government announced in July 2017[28] that, for the time being, the electrification would only be completed as far as Thingley Junction, two miles west of Chippenham
Chippenham
on the Swindon
Swindon
to Bristol
Bristol
Temple Meads section of the route. At the same time the Cardiff to Swansea section, that from Bristol
Bristol
Parkway to Bristol Temple Meads, and Didcot
Didcot
to Oxford were also postponed. The government argued that bi-mode trains will fill in the gaps pending completion of electrification, although the Class 800 trains are much slower in diesel mode than under electric power. The electrification as far as Didcot
Didcot
Parkway was completed in December 2017. In addition to allowing Crossrail
Crossrail
services with the new Class 345 EMUs, the electrification allowed the introduction of Class 387 EMUs by GWR. It was originally planned to bring second-hand Class 365s from Great Northern after the arrival of their new Class 700 trains[29] but it was later decided to order new Class 387s for GWR instead. Eight were delivered during 2016, with more on order to bring the total to 45. Some of the Class 165 and Class 166 DMUs currently used by GWR for Thames Valley
Thames Valley
services will be displaced to services on the lines around Cardiff and Bristol.[30] The line will also be used by the new Hitachi Super Express
Hitachi Super Express
high speed trains – the Class 800s and Class 802s – which will gradually replace the InterCity 125
InterCity 125
and Class 180 sets currently used for the long-distance services. Other proposals[edit] Network Rail
Network Rail
plans to install European Rail Traffic Management System (ERTMS) in-cab signalling on the Great Western line;[31][32] this is a pre-requisite for the Super Express trains to run at 140 mph (225 km/h).[33] Some or all of the resignalling work will be undertaken during the electrification work.[31] Further capacity improvements are also scheduled at Swindon, adding to recent changes and the new Platform 4. Crossrail
Crossrail
services are planned to terminate at Reading. Some of the current suburban services into London Paddington
London Paddington
are planned to be transferred to the new Crossrail
Crossrail
service, which will in turn free up some surface-level capacity at London
London
Paddington.[31] Other more distant aspirations include resignalling and capacity improvements at Reading; the provision of four continuous tracks between Didcot
Didcot
and Swindon
Swindon
(including a grade-separated junction at Milton, where westbound relief line switches from the north side of the line to the south); and resignalling between Bath and Bristol
Bristol
to enable trains to run closer together. Access to Heathrow Airport
Heathrow Airport
from the west remains an aspiration and the 2009 Heathrow Airtrack
Heathrow Airtrack
scheme, abandoned in 2011, proposed a route south of the Great Western main line
Great Western main line
to link the airport with Reading. Plans for electrification of the line will make it easier to access Heathrow from Reading, since lack of electrification between Reading station and Airport Junction (near West Drayton
West Drayton
station) was a limiting factor.[31] Plans under consideration in 2014 included new tunnels between Heathrow and Langley.[34] Network Rail
Network Rail
intends to replace the ATP system with ETCS – Level 2[35] from 2017 to 2035 along with the introduction of the new IEP trains. Signalling Solutions is to resignal the 12 miles from Paddington to West Drayton, including the Airport branch, as part of the Crossrail project.[36] Calls for station reopenings[edit] There are calls for the reintroduction of Corsham station due to recent growth of the town.[37] The original station was closed to passengers in 1965. A local group is campaigning for the reopening of Saltford station between Bath and Bristol, to coincide with electrification.[38] There have also been calls to reopen the former Wantage Road station.[39] Oxfordshire County Council
Oxfordshire County Council
include a proposal for a new station to serve for Wantage and Grove in their 2015-2031 local transport plan.[40] Major incidents[edit]

Slough rail accident - 16 June 1900 - An express train from Paddington to Falmouth Docks ran through two sets of signals at danger and collided with a local train heading for Windsor. Five passengers were killed and 35 seriously injured. Ealing
Ealing
rail crash - 19 December 1973 - A train from Paddington to Oxford derailed after a loose battery box cover on the Class 52 "Western" locomotive hauling the train struck lineside equipment, causing a set of points to move under the train. Ten passengers were killed and 94 injured. Southall
Southall
rail crash - 19 September 1997 - An InterCity 125
InterCity 125
service from Swansea to Paddington, operated by Great Western Trains, failed to stop at a red signal and collided with a freight train entering Southall
Southall
goods yard. Seven people were killed and 139 were injured. The incident severely damaged public confidence in the safety of the rail system. It was found that the train's AWS was faulty, and the driver had been distracted (he had bent down to pack his bag). Great Western Trains was fined £1.5 million for violations of health and safety law in connection with the accident. Ladbroke Grove rail crash
