The initial service will call at Cardiff Central, Newport, Severn Tunnel Junction and Bristol Parkway, then express to London Paddington. The service will also stop at Cardiff Parkway once it is opened.
We propose to extend the service in 2023, which will extend the calling points from Cardiff Central to Bridgend, Port Talbot Parkway, Neath, Swansea, Gowerton and Llanelli.
