Editing Cardiff (section)

===Metro===
The [[South Wales Metro]] is an integrated public transport system under development in south-east Wales, centered on Cardiff. The project is to include the electrification of some of the existing railway lines and the creation of multiple [[light rail]] and [[light rapid transit]] lines. Four lines are under construction with a further three planned. The first lines will link [[Penarth]] and [[Cardiff Bay]] to {{rws|Radyr}}, {{rws|Treherbert}}, {{rws|Aberdare}} and {{rws|Merthyr Tydfil}}, with plans to also serve [[Pontyclun]], [[St Mellons]] and [[Porth Teigr]]. Alongside this, current commuter services will be improved with a near-tripling in capacity on some routes to {{rws|Bridgend}} and {{rws|Rhymney}}.
