Arriva Train Wales ticket prices will rise by 3.3% from today, 2 January 2018, which will see a season ticket between Bangor and Llandudno increasing by £40.
The average rail ticket prices will rise by 3.4% across the UK, which is the biggest increase in five years.
Protests are planned at 40 stations across the UK. The National Union of Rail, Maritime and Transport Workers (RMT) called the rises “eye watering” but the Department for Transport said price rises were capped in line with inflation
RMT General Secretary Mick Cash said: “It’s another New Year and yet another hike in fares for passengers. These eye watering increases will make it even harder for workers to get by.”
Stephen Joseph, chief executive of the Campaign for Better Transport (CBT), accused the UK Government of choosing to “snub rail passengers” by continuing to raise fares while fuel duty is frozen for a 17th consecutive year.
But the Department for Transport said 97p out of every £1 paid by rail passengers went back into the railway.
“We are investing in the biggest modernisation of our railways since the Victorian times,” a spokesman added.
