Transport for Wales have made significant progress upgrading the Core Valley Lines following our over £1bn investment. This has enabled brand-new electric trains to run on the network for the first time ever as part of our £800m investment in new rolling stock. Transport for Wales remain on course to increase service frequency on the Core Valley Lines following the roll-out of Stadler Class 398 tram-trains from next year.
