IF you were affected by train timetable chaos this year, the Transport Committee wants to hear from you.

The committee is keen to receive written evidence from passenger groups and industry stakeholders about what went wrong and how to put it right.

Lilian Greenwood MP, chair of the Transport Committee, said: "As if passengers had not been suffering enough with high fares and varying levels of service, the May 2018 timetable change caused additional upset and distress.

"Our inquiry aims to unpick what went wrong and where responsibility falls and consider how the industry can put things right.

"Before we look at steps taken to improve the situation and compensation, we want to hear the experiences of passengers themselves.

"I strongly encourage them to engage with us via the Committee’s Twitter account or submit written evidence to our inquiry."
