The Chancellor is expected to announce new plans for a discount rail card for young people across the UK.
The announcement will come in Wednesday’s budget and could benefit around 200,000 young Welsh rail users.
There are 195,259 people aged 26-30 in Wales who will be eligible for the new railcard.
Combined with the current 16-25 railcard this means that 597,817 young people in Wales are eligible for discounted travel with a railcard.
It is expected the card will work on a similar basis to the one for 16-25 year olds, which has been active in one form or another since 1974.
Commenting on the announcement, Shadow Economy Secretary, Russell George, said:
“This announcement is great news for people under 30, who will now be able to enjoy cheaper fares on trains.
“The UK Government is taking steps to help keep the cost of living down and this would affect around 4.5 million young people.
“Rail fares have been a contentious issue for many years, and it’s good to see this issue being tackled head on by a Chancellor who understands the concerns of everyday commuters.
“This new discounted rail card will help young people who are feeling the squeeze to keep more of their hard earned cash.”
