Don't be silly. I am sure you can understand what I'm saying. Trying to claim that because some marketing drivel might mean that anything that NRE says is law is incorrect as the terms and conditions state.
Hum, I must disagree that NRE is "marketing drivel". It is what ATOC tells the consumer is the definitive source of advice. While it is not, as you say, law the Unfair Terms in Consumer Contracts Regulations (1999) certainly is. That clearly states that if a contractual term creates an unfair balance in detriment to the consumer it can be suppressed. By definition the accuracy exclusion hidden in the small print of NRE falls foul of this.
Now it may be that the railway industry is exempt from the Regulations but I think any TOC taking legal action and relying on that exclusion (ATOC - a group of TOCs- telling you where to go and look for information and then one of those very same TOCs penalising you whan that very same information is inaccurate.....) would be opening themselves and ATOC to a whole mountain of grief, including demands for a revisit to the legally obsolescent consumer unfriendly legislation around railway fares - the Daily Mail and/or Express will mount a new campaign!!!
Will they open that Pandora's box? Not a chance.
