The South Wales Metro (Welsh: Metro De Cymru) is an integrated heavy rail, light rail and bus-based public transport services and systems network being developed in South East Wales around the hub of Cardiff Central railway station.The development will also include the electrification of the core Valley Lines and new stations: all nine lines will be electrified.

The first phase was approved for development in October 2013. A new depot was constructed at Taff's Well and new trains were built by Stadler Rail in Switzerland. The first few of the new Stadler trains entered service late 2024, and the first tram-trains will enter service in the second half of 2025. The first phase of the service is expected to be fully in operation by the start of 2026.
