Trains and stations

While Metro is more than just rail, our rail services will play a key role in the South Wales Metro and we’re investing in new faster, greener trains to provide a modern, turn-up-and-go Metro service.  We’re also updating our stations.

We’re busy behind the scenes building the new, more comfortable trains that will provide our customers with a modern, effective, turn-up-and-go Metro service and you’ll start to see these in service from 2022.
These trains will significantly increase our capacity and transform our customers’ travelling experiences.  They’ll also offer lots of new features including level boarding, increased bicycle storage space and air conditioning.
