Eighteen-year-olds in the UK will be able to buy half-price train tickets on most services after the Department for Transport changes railcard rules later this month, according to BBC. From 17 August, the 16-17 Saver railcard will be valid for a full year from the date of purchase, meaning 17-year-olds can buy it until the day before they turn 18 and use it until the day before they turn 19. The DfT said the change will help more than 70,000 students a year who were previously an average of £175 worse off once they turned 18. The railcard costs £35 a year and gives 50% off most train fares. Rail minister Lord Hendy said the move was a “common sense change”, while the government also plans to cut the cap on most single bus fares in England from £3 to £2 next year.
