The new trains, many made in Wales, are part of the Welsh Government’s £800m investment to transform rail services in Wales.
Offering increased capacity, improved seating, modern air conditioning, power sockets, Wi-Fi and up-to-the minute passenger travel information screens, customers are already reaping the benefits of these improvements.
As a result, two thirds of passenger journeys in Wales are now on new and improved trains.
Speaking on a visit to the CAF depot where some of the brand-new trains are made, Cabinet Secretary for Transport, Ken Skates said: “This is a significant milestone on our mission to transform our railways.
“These brand-new, modern trains are transforming passenger experiences on Wales and the Border lines with faster and more frequent services thanks to our unprecedented £800 million investment.
