Make of this trend what you will.
Fare increases have vastly slowed (versus inflation) since British Rail. https://books.google.co.uk/books?id=vAlCWxoV1NYC&lpg=PA277&p... shows average annual fare increase and RPI for the last 14 years of British Rail.
Over the last ten years of BR, fares increased 102% versus RPI of 62% (thus increasing 25% in real terms based on RPI; CPI didn't exist till the final five years of BR).
Over the past ten years, fares have increased 40% versus RPI of 31% (thus increasing 7% in real terms based on RPI, or 16% based on CPI).
