The arts minister had a last-minute rush to announce the next UK City of Culture after the train he was on was stranded for hours.
Dozens of passengers were aboard the 09:48 service, with Hull Trains blaming a "catastrophic engine failure".
Hull Trains apologised to those on board the service.

Engineers initially thought the train had struck something, but it later emerged it had suffered engine problems.
A Hull Trains spokesperson said:"We have now been able to move passengers on to another train which will take them to Peterborough and on to their destinations."
In a tweet, the Conservative MP for Salisbury praised the staff onboard the service for being "magnificent" and said he had filled his time by writing Christmas cards.;
