As we reported earlier, transport secretary Chris Grayling has been heavily criticised by MPs for not being proactive enough in preventing the chaos following May's new timetables.
In a scathing report on May's timetable changes, the Transport Committee said "genuine change" was needed to restore trust in the railways.
Chair Lilian Greenwood says Mr Grayling still "hasn't got the message".
She is urging ministers to act on the committee's recommendation that 2019 fares are discounted for passengers who've suffered the worse disruption.
"Ministers need to listen and think again, urgently," she says.
