Three sets of modern Mark 4 carriages are being introduced on Cardiff-Holyhead services, taking in stations in the county.
The will include the “Gerald of Wales” Premier Services which the train company says will give travellers an intercity experience.
As part of the distinctive branding of the trains, each of the end carriages – known as the Driving Van Trailers, will feature a livery promoting a charity.
Two will be Alzheimer’s Society Cymru and Ty Gobaith/Hope House Children’s Hospice. For the third charity, TfW is running a public poll to choose between three nominated charities: Mind Cymru, the Royal National Lifeboat Institution (RNLI), and Wales Air Ambulance
The poll will run between until February 17 on Twitter.
James Price, Transport for Wales chief executive, said: “The introduction of new rolling stock to our fleet is always a landmark moment, but I’m delighted that we are making it a little more special by using this as an opportunity to celebrate and promote the great work that our leading charities do.
“This is particularly important during this challenging time when so many people are reliant on the support that these charities provide. It will undoubtedly be a very competitive poll, and all three nominated charities will be worthy winners. I wish everyone involved the very best of luck.”
Transport for Wales will be introducing Mark 4 carriages on Cardiff-Holyhead services from the May timetable change. These will replace the older Mark 3 carriages which currently operate on a limited number of services.
