The thread title was the headline of a Times article today. What's behind it is
ORR» pursuing
TOCs▸ and independent ticket sellers for not showing up-to-date information about trains not running, being altered, involving bustitution, etc. This arose partly from routine monitoring of their performance, partly from looking at the T-x issue which has meant more ticket sales are involved.
There is quite a lot of material on the ORR site about this:
The annual (or so it says)
report on consumer service performance.
There is not much to see yet about the May 2018 inquiry, but there is for the
timetabling inquiry (including T-12) which started earlier.
Within this, the
latest letter (10th July) is presumably the one the Times takes to be threatening legal action - I'm not sure it quite does that, though it does remind TOCs of their licence conditions.
You may find the
collation of industry responses to an earlier ORR letter interesting, as much for what it says about the TOCs booking engines as anything else.
There seems to be an implied judgement or assumption (or it may be explained somewhere I've not looked) that the
NRE‡ Journey Planner is kept up to date.
