Cambrian Line

From Shrewsbury, the line heads west through northern Powys, serving the towns of Welshpool and Newtown, then continues further west calling at Caersws and then Machynlleth until reaching . At Dovey Junction, a short distance west of Machynlleth, the line splits into two branches: the southern branch goes to Aberystwyth, and the longer, northern branch continues to Pwllheli as the Cambrian Coast Line, crossing the River Mawddach by Barmouth Bridge. The section of the Cambrian Line between Shrewsbury and Aberystwyth may be called the Cambrian Main Line. ==History==

The line comprises: • Shrewsbury and Welshpool Railway between Shrewsbury and Buttington • Oswestry and Newtown Railway between Buttington Junction and Newtown • Llanidloes and Newtown Railway between Newtown and Moat Lane Junction • Newtown and Machynlleth Railway between Moat Lane Junction and Machynlleth • Aberystwith and Welsh Coast Railway between Machynlleth and Aberystwyth/Pwllheli. These lines were constructed between 1855 and 1869. The section west of Buttington Junction became part of the Cambrian Railways in 1864. The Cambrian Railways became part of the Great Western Railway under the Grouping Act of 1921. On nationalisation, these lines were operated first by the Western Region of British Railways and later by the London Midland Region. In a later reorganisation, passenger services were operated by the Regional Railways Central sector. Following privatisation in the mid 1990s, passenger services were first operated by Central Trains, then by Wales & Borders from 2001, Arriva Trains Wales from 2003, KeolisAmey Wales from 2018 and publicly-owned Transport for Wales from 2021. Closed stations Although the line survived the Beeching Axe, many stations were closed from the 1960s onwards: Shrewsbury to Dovey Junction: • • • • • • (connection with the Cambrian Railways line to Oswestry) • • • • • Moat Lane Junction (connection with Mid Wales Railway to Brecon) • • (reopening proposed, application at final stage) • • • • (connection with Mawddwy Railway to ) Dovey Junction to Aberystwyth: • • • • (reopened in 2021) Dovey Junction to Pwllheli: • • • • • (connection with the Carnarvonshire Railway to ) • The Ruabon bound platforms at were also closed in 1965 and the station renamed Morfa Mawddach. ==Politics==

The Cambrian line was not directly threatened with closure in the 1963 Beeching Report. Later threats to the coastal part of the route, from Dovey Junction to Pwllheli, were subsequently withdrawn. Its tourism role is as a scenic route, as well as linking many coastal resorts and connecting to five narrow-gauge tourist lines (these are the Talyllyn Railway, Welshpool and Llanfair Railway, Ffestiniog Railway, Welsh Highland Railway and the Vale of Rheidol Railway). ==Performance==

With long sections of single line and limited passing points, minor disruptions on the Cambrian Line quickly lead to compound delays and partial cancellations. This, combined with short turnaround times at each end of the route, led to severe unpunctuality during much of the first decade of the 21st century. The extension of the service to Birmingham International in late 2008 has helped address this by eliminating the tight turnarounds at the heavily congested Birmingham New Street station. Maintenance changes and additional padding in public timetables has also helped improve performance figures overall. In Arriva Trains Wales' performance statistics, the Cambrian Line was routinely the worst-performing service group between 2003 and 2008. Since early 2009, recorded timekeeping has improved – a considerable achievement, considering that the route has been the testing ground for brand new signalling technology previously unused on the British railway network. ==Line upgrade==

In October 2006, it was announced that Network Rail would pilot the European Rail Traffic Management System on the Cambrian Line. The ERTMS allows headways between trains using the same track to be reduced without affecting safety, allowing a more frequent service. Should the pilot scheme be successful, the system is expected to be rolled out on some other rural routes within the UK. The upgrade was expected to cost £59 million and was to be completed by December 2008, but the system was only released for limited testing, between Pwllheli and Harlech, in February 2010. Three signallers from the Machynlleth signalling centre and seven drivers were trained to operate the new equipment. Ansaldo STS were the principal contractors for the upgrade, with Thales as sub-contractors for the Telecomms and Eldin as installation subcontractors for all elements of UK infrastructure. Systra was in charge of testing and commissioning the ETCS and interlocking components of the signalling system. Ansaldo installed ERTMS In Cab ETCS (European Train Control System) level 2, class 1, specification V2.3.0 in 2011 (as noted below). As the name suggests, the driver receives the instructions for movement on the cab display. This level does not require conventional fixed signals – therefore all the existing signals and RETB boards have been removed. Additionally, the line side speed signs were made redundant – drivers are given the appropriate maximum speed on the cab display (in kilometres per hour). 2018 track upgrades In 2018, Network Rail began upgrading of track at a cost of £7.5 million. As well as improving reliability by replacing track, Network Rail and Powys County Council installed over a mile of new road and two road over rail bridges at Ystrad Fawr and Rallt. This has closed eight level crossings and improved safety for local residents. ETCS upgrade announcement 2020 The UK Government's Transport Secretary Grant Shapps announced on 21 August 2020 that £3m in funding had been authorised to advance plans to upgrade signalling on the Cambrian line from Shrewsbury Sutton Bridge Junction to Aberystwyth and Pwllheli. "The planned state-of-the-art digital signalling system will modernise the network, improving reliability of services, and supporting the introduction of a new fleet being rolled out across the network in December 2022", the minister said. == Accidents and incidents ==

Abermule 1921 The worst accident on the Cambrian Line – and the worst on the former Cambrian Railways system – occurred on 26 January 1921 on the single-tracked line between and . A westbound stopping train from set off from Abermule without the correct authority, and collided head-on with an eastbound express from . Seventeen people were killed, including the driver and fireman of the stopping train. 2009 level crossing incident On 2 September 2009, a Class 97/3 locomotive, operated by Network Rail, collided with a Fiat Punto on a user worked crossing near Penrhyndeudraeth. The driver of the car, an 83-year-old local resident, was killed in the collision. Prior to her death, the victim had been a regular user of the level crossing for more than 40 years, and relied on her knowledge of passenger train timetables to determine when it was safe to cross. On the day of the collision, she had not used the telephone prior to crossing. Llanbadarn level-crossing incident Shortly before 22:00 on Sunday 19 June 2011, a passenger train from to ran onto the level crossing at Llanbadarn while the barriers at the crossing were raised, and came to a stop with the front of the train about beyond the crossing. There were no road vehicles or pedestrians on the crossing at the time. The immediate cause of the incident was that the train driver did not notice that the indicator close to the crossing was flashing red until it was too late for him to stop the train before it reached the crossing. Factors behind this included the driver's "workload" (his need to observe a screen in the cab at the same time as he should also be observing a lineside indicator), the design of the equipment associated with the operation of the level crossing, and the re-setting of the signalling system on board the train before it could depart from Aberystwyth. An underlying cause of the incident was that the signalling system now in use on the lines from Shrewsbury to Aberystwyth and Pwllheli did not interface with the automatic level crossings on these routes. The incident resulted in one death and fifteen injuries. Initial inspections by the RAIB found evidence of low rail head adhesion. ==Services==

As of May 2023, the Aberystwyth line has a near-hourly service and twelve direct trains between Aberystwyth and Shrewsbury daily, with several extended to or from Birmingham International. Trains to Pwllheli typically operate once every two hours, either as separate connecting services running to/from Machynlleth, or as portions attached to Aberystwyth services with trains dividing or joining at Machynlleth as necessary. Trains now run more frequently than before: resignalling of the railway and other infrastructure changes have allowed more trains to run to and from Aberystwyth since 2015. Connections are better too, as some trains run through from Birmingham New Street to Birmingham International. From the 1990s until 2015, a service had typically been provided between Birmingham and Aberystwyth every two hours, with a reduced service on Sundays. From December 2009 to December 2022, connections were available through calls at . Freight services over the line were absent for many years, after regular oil trains were halted in 1993. However, trials in 2003 and again in 2022 have led to the introduction of a regularly weekly train transporting timber from Aberystwyth to the Kronospan woodchip factory in Chirk. Trains are operated by Colas Rail but are hauled by Class 97 locomotives belonging to Network Rail, due to the need for trains on the route to be compatible with the ETCS signalling used on the line (97/37 combinations with the 97 in front of the 37 can also be used). The 2003 trial, by contrast, had used a pair of British Rail MPV units sandwiched around a rake of seven open-sided timber wagons. ==Steam workings==

In 2007, West Coast Railways took over operation of the Cambrian Coast Express which ran over the Cambrian Coast Line from Machynlleth to Porthmadog and Pwllheli, the train was also renamed to The Cambrian. The service would run from the last week of July until the end of August between 2007 and 2010. Before the 2011 season, WCR issued a statement stating that due to Network Rail's implementation of the new European Rail Traffic Management System (ERTMS) signalling on the Cambrian Coast, which necessitated new in-cab signalling equipment, the seasonal steam services had to cease running because no system was yet available for fitment in steam locomotives. No steam loco owners were planning to upgrade their locos to work under the system in the then-near future, owing to costs and the amount of equipment that was required. Locos that have visited the route over the years include: 7802 Bradley Manor, 7819 Hinton Manor, 44871, 46443, 75069 & 76079. Following an absence of 14 years, it was announced, in February 2024, that as part of trials for the fitment of the new ETCS signalling system to steam locomotives, 60163 Tornado is to run overnight testing trains between Shrewsbury and Newtown. The trains will be run during night-time to avoid affecting passenger services. These trials are also being undertaken as part of Network Rail's East Coast Digital Programme & Pathfinder Project. ==Coast Line infrastructure problems==

Major structural problems with Barmouth Bridge resulted in the withdrawal of services between 1980 and 1986 and the line was threatened with closure before ultimately being repaired and reopened. Work began in March 2013 to replace the wooden Pont Briwet viaduct over the Afon Dwyryd near . The new bridge now carries two lanes of road traffic and the single track railway, and opened in 2015. It was hoped that, apart from a four-week period where power cables had to be moved, the old viaduct could remain open throughout the works. However, the bridge was found to have been affected by the piling work for the new bridge, and was declared structurally unsafe and closed in December 2013. This necessitated a diversion via Maentwrog for road users and caused rail services to terminate at . A new temporary bridge was due to open in Spring 2014, but this plan had been scrapped in favour of running a convoy system on the A496 road that served as the diversionary route. Work then focused on completing the main railway and road bridge by the end of the year. In January 2014, the Coast line from Dovey Junction was closed to all trains after two sections of track between and were severely damaged by storm-force winds and tidal surges at the beginning of the month. Part of the sea wall protecting the trackbed at Llanaber near Barmouth was washed away, resulting in some 300 tons of ballast being lost and the formation covered in debris, whilst further south a section of embankment at Tonfanau was washed out. Two of Arriva Trains Wales's trains were trapped at Barmouth, and were removed by road. Network Rail described the damage suffered by the line as "devastating", but stated the line to Barmouth could be reopened , which it was. Repairs north of Barmouth were completed, and the line reopened to Harlech on 1 May 2014, two weeks ahead of schedule. The full line reopened on 1 September 2014. ==See also==
