The '''Merthyr line''' is a [[Commuter rail in the United Kingdom|suburban rail line]] in [[South Wales]]; it connects {{rws|Cardiff Central}} with {{rws|Merthyr Tydfil}} and {{rws|Aberdare}}. The line is part of the Cardiff suburban rail network, known as the ''[[Valley Lines]]''.

==History==
Historically, the line was the [[Taff Vale Railway]] (TVR), the first rail development in the [[South Wales Valleys|Valleys]] in the 1840s. It was associated with the notorious [[Taff Vale Railway Co v Amalgamated Society of Railway Servants|Taff Vale Judgment]] in 1901, when the courts penalised trade unions for losses caused by strikes.

The Aberdare line was closed in 1964 under the [[Beeching Axe]]. The line was reopened in 1988, in an attempt to stimulate jobs and employment in the valley in response to the closure of the last few coal mines.

In 2005, following further grant from the Welsh Assembly, the stations at {{rws|Abercynon}}, {{rws|Penrhiwceiber}}, {{rws|Fernhill}}, {{rws|Cwmbach}} and {{rws|Aberdare}} were extended to four-car length to accommodate longer peak trains in an initiative to relieve overcrowding; train leasing/running costs were funded by the [[Welsh Assembly Government]].

==Route==
The line follows the [[Rhondda line]] as far as {{rws|Pontypridd}}, serving {{rws|Cathays}}, {{rws|Llandaf}}, {{rws|Radyr}}, {{rws|Taffs Well}} and {{rws|Treforest}}. It then divides at Abercynon, with separate branches to Merthyr and Aberdare up diverging valleys.

The Merthyr branch serves {{rws|Quakers Yard}}, {{rws|Merthyr Vale}}, {{rws|Troed-y-rhiw}}, {{rws|Pentre-bach}} and Merthyr Tydfil. The Welsh Assembly confirmed in February 2007 that it was grant funding a scheme to upgrade the line north of Abercynon, in conjunction with [[European Union]] Objective 1 assistance. This included reinstatement of two miles of double track, to enable the introduction of a half-hourly train service; the revenue costs of which the Welsh Assembly also met. The enhanced service was said to commence in 2008 but was postponed to May 2009.<ref>{{cite web |url=http://www.walesonline.co.uk/news/south-wales-news/merthyr/2009/04/02/half-hourly-trains-to-the-capital-91466-23285668 |website=Wales Online |title=Half-hourly trains to the capital |date=2 April 2009 |access-date=14 May 2009}}</ref>

The Aberdare branch serves {{rws|Penrhiwceiber}}, {{rws|Mountain Ash}}, {{rws|Fernhill}}, {{rws|Cwmbach}} and Aberdare. Although following the original TVR route, beyond the former {{rws|Abercwmboi Halt}} to access [[Tower Colliery]], the line diverts onto the route of the former [[Vale of Neath Railway]]. The line continues beyond Aberdare, for goods purposes only, to serve Tower Colliery, which was the last deep coal mine to remain open in South Wales. Mountain Ash station was redeveloped with a grant from the Welsh Assembly Government in the early part of the decade, the scheme including the provision of a new station and a passing loop to permit an upgrade of the passenger service to two trains per hour from late 2003. There are a few gaps in the half-hourly service to enable coal/stone trains to run to/from Tower Colliery/Hirwaun.

==Services==
The line is currently operated by [[Transport for Wales Rail|Transport for Wales]] (TfW), as part of the ''[[Valley Lines]]'' network.

Both the Merthyr and Aberdare branch lines have a half-hourly service during the day, which decreases to hourly in the evening. The Sunday service frequency decreases to hourly.<ref>{{Cite web |title=Timetables |work=Transport for Wales |date=2 June 2024 |access-date=13 October 2024 |url=https://tfw.wales/service-status/timetables}}</ref>

In December 2017, the-then operator [[Arriva Trains Wales]] introduced extra Sunday morning services on the Aberdare line on a trial basis. This was in response to demand from the local [[Member of the National Assembly for Wales|Assembly Member]].<ref>{{cite web|url=https://arrivatrainswales-newsroom.prgloo.com/news/christmas-boost-for-cynon-valley-as-arriva-trains-wales-confirms-pilot-of-extra-sunday-services|title=Christmas boost for Cynon Valley as Arriva Trains Wales confirms pilot of extra Sunday services|website=Arriva Trains Wales News|access-date=6 December 2017|archive-url=https://web.archive.org/web/20171207014940/https://arrivatrainswales-newsroom.prgloo.com/news/christmas-boost-for-cynon-valley-as-arriva-trains-wales-confirms-pilot-of-extra-sunday-services|archive-date=7 December 2017|url-status=dead}}</ref> The trial was deemed a success and the extra Sunday services were made permanent from April 2018.<ref>{{Cite web |url=https://arrivatrainswales-newsroom.prgloo.com/news/extra-sunday-aberdare-services-confirmed-after-successful-trial |title=Extra Sunday Aberdare services confirmed after successful pilot |access-date=28 April 2018 |archive-url=https://web.archive.org/web/20180428182030/https://arrivatrainswales-newsroom.prgloo.com/news/extra-sunday-aberdare-services-confirmed-after-successful-trial |archive-date=28 April 2018 |url-status=dead }}</ref>

==Extension to Hirwaun==
[[File:Coal from the Tower Mine heads away towards Aberdare. - geograph.org.uk - 804398.jpg|thumb|left|EWS [[British Rail Class 66|Class 66]] moves coal from Tower Colliery towards Aberdare, 2006]]
Since its termination at Aberdare, following the [[Beeching cuts|Beeching Axe]], there have been various proposals to extend the line northwards towards Hirwaun again. In recent years, these have been driven by the Welsh Assembly Government.

In 2006, a study by local transport alliance [[Sewta]] appeared to rule out any such extension for the foreseeable future.

In November 2009, the Welsh Assembly sponsored [[Network Rail]] in a feasibility study to reopening both the section to Hirwaun, and parts of the former [[Anglesey Central Railway]] between {{rws|Llangefni}} on [[Anglesey]], and {{rws|Bangor|Gwynedd}}. Network Rail began work on gathering evidence for its study, beginning with cutting away vegetation on track sections to examine the condition of rails and track bedding. Its report was expected to be published in early 2010, before any business case to reopen the lines can be developed.<ref>{{cite news |url=http://news.bbc.co.uk/1/hi/wales/8346748.stm |title=Old tracks could see trains again  |date=5 March 2009 |access-date=6 November 2009 |work=BBC News}}</ref>

It was announced in March 2011 that the Welsh Assembly Government's 2011–12 capital programme would include the reopening of the line to {{rws|Hirwaun}} as part of the Cynon Valley Scheme<ref>{{cite web |url=http://www.walesonline.co.uk/news/local-news/aberdare/2011/03/24/aberdare-to-hirwaun-rail-line-set-to-reopen-91466-28381233/ |title=Aberdare-to-Hirwaun rail line set to reopen |website=WalesOnline |date=24 March 2011| publisher=walesonline.co.uk}}</ref> although the project appears to have advanced little at that time. In 2019-2020, the [[Cardiff Capital Region|Cardiff Capital Region's]] transport authority secured £100,000 of funding from the Welsh Government's Local Transport Fund to undertake a Welsh Transport Appraisal Guidance (WelTAG) 1 study into the feasibility of extending Aberdare Line passenger services through reopened {{rws|Trecynon Halt}} and Hirwaun stations to a new terminus serving the [[Tower Colliery|Tower strategic development site]].<ref>{{Cite web |last=Gupwell |first=Katie-Ann |date=2 July 2020 |title=Brand new train station to be built as part of £2m valleys railway line improvements |url=https://www.walesonline.co.uk/news/local-news/brand-new-train-station-built-18526685 |archive-url=|archive-date=|access-date=23 December 2020 |website=Wales Online}}</ref>

As already noted, the line is now closed above Aberdare, but the aspiration to reopen with a passenger service remains and so the track is being retained in situ.

==Electrification==
On 16 July 2012,  plans to electrify the line were announced by the Government as part of a £9.4bn package of investment of the railways in England and Wales.<ref>{{cite news| url=https://www.bbc.co.uk/news/uk-18851907 |work=BBC News| title=£9bn Railway Investment Announced By Coalition |date=16 July 2012}}</ref>

The announcement was made as an extension of the electrification of the [[South Wales Main Line]] from Cardiff to {{rws|Swansea}}; the electrification of the south Wales [[Valleys & Cardiff Local Routes|Valley Lines]] at a total cost of £350&nbsp;million. The investment requires new trains and should result in reduced journeys times and cheaper maintenance. Work was expected to start between 2014 and 2019.<ref>{{cite news| url=https://www.bbc.co.uk/news/uk-wales-18852955 |work=BBC News| title=Rail electrification to Swansea and south Wales valleys welcomed | date=16 July 2012}}</ref>

However, as part of Welsh Government's [[South Wales Metro]] this line has been taken over,<ref>{{Cite web |title=Impact of Core Valley Lines divestment on the Wales & Western region |url=https://www.orr.gov.uk/sites/default/files/2020-09/divestment-of-core-valley-lines-in-the-wales-and-western-region-2020-07-15.pdf |access-date=23 April 2022 |website=orr.gov.uk}}</ref> and is now being electrified<ref>{{Cite web |title=Core Valley Lines Transformation {{!}} Transport for Wales |url=https://tfw.wales/projects/metro/south-wales-metro/work-progress |access-date=23 April 2022 |website=tfw.wales}}</ref> in preparation for new [[British Rail Class 398|Class 398]] tram-train rolling stock.<ref>{{Cite web |title=Transport for Wales: meet the fleet |url=https://railcolornews.com/2019/12/04/uk-transport-for-wales-meet-the-fleet/#:~:text=These%20Class%20398%20tram%2Dtrains%20will%20stretch%20their%20wheels%20on%20the%20Treherbert%2C%20Aberdare%2C%20and%20Merthyr%20lines. |access-date=2022-04-23 |website=Railcolornews}}</ref>
