Rail thumb|Rail network of Wales, 2021|226x226px Rail transport in Wales includes the Wales & Borders franchise, which is overseen by the Welsh Government with most passenger services operated by Transport for Wales Rail. The Cardiff region has its own urban rail network.

Services between north and south Wales operate through the English cities of Chester and Hereford and towns of Shrewsbury, Gobowen for Oswestry and along the Welsh Marches Line, with trains on the Heart of Wales Line from Swansea to Llandovery, Llandrindod and Knighton, connecting with the Welsh Marches line at Craven Arms. Trains in Wales are mainly diesel-powered but the South Wales Main Line branch of the Great Western Main Line used by services from London Paddington to Cardiff is undergoing electrification, although the programme has experienced significant delays and cost overruns.; ; A North-South railway has been suggested to better link North and South Wales.
