The Transport Select Committee are asking people who were caught up in the recent rail fiasco to send in written evidence that will be considered as part of an enquiry.
It all began when a new timetable was introduced in May but immediately collapsed meaning hundreds of trains were cancelled every day.
Passengers were left on platforms and even if they did manage to get on a train were often crammed in.
Eventually an emergency timetable was introduced which led to some trains in the Lake District being completely cancelled.
The Transport Select Committee are now looking into the fiasco and are collecting evidence.
Chair of the Committee, Lilian Greenwood MP, 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. What are the key lessons and who needs to learn them? We have already taken evidence from Northern, GTR and Network Rail and are holding a further session on Monday with the Thameslink 2018 Industry Readiness Board.
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."
