Not sure if it's been brought up, but Britain Runs on Rail are looking at changing the
UK▸ rail fare structure.
Some interesting ideas, including rail fare caps for season ticket passengers, and bringing it even higher prices for peak services and lowering further off peak services
I found it on the
LNER» website, Not many
TOC▸ 's seem to making the public aware of it.
Here's the link for those who want to have a say.
