The inflation figure usually used to determine annual increases in some train fares has risen to its highest in nearly 40 years.
The Office for National Statistics data showed July’s Retail Prices Index (RPI) inflation was 12.3%, up from 11.8% the previous month and the highest since January 1982.
July’s RPI figure is traditionally used by the UK, Scottish and Welsh Governments to set the cap on the following year’s increase in regulated train fares, which include most season tickets on commuter routes.
