Nearly two-thirds (70%) of Transport for Wales services will be operated on new trains following timetable changes this weekend.
Brand new class 756 trimode trains will also be introduced onto the Coryton and Penarth lines later this summer, further increasing the number of new trains providing services on the Wales and Borders network.
Rail customers across Wales and the Borders network are being urged to check their journey details prior to travel with a new rail timetable coming into effect on Sunday.
On the core Valley Lines the first of 36 new tram-trains will be pressed into service later this year and will be fully operational next year in a phased introduction.
Transport for Wales’ planning and performance director Colin Lea said: “We’re pleased to be delivering a number of small, but important changes across our network that we think will make a big difference for customers.
“Some later services on busy routes, longer trains in the summer to holiday destinations and the continued roll out of brand-new trains as part of an £800m investment by the Welsh Government are among the key highlights.
Also on Sunday a new second platform will open at Aberdare station, This will enable more services to run on the Aberdare line once £1bn South Wales Metro electrification programme is complete.
Alongside the new platform, a new track loop has been installed. This new infrastructure is crucial for increasing the frequency of trains from Aberdare to Cardiff, to deliver four trains per hour when all the new tram-trains are in service.
