Hull Trains need a quick fix ahead of a new fleet coming into use next year.
That's according to Hull North's MP as passengers continue to face delays.
Hull Trains have apologised and say they're still repairing the trains affected by the recent snow and ice.
Diana Johnson says something needs to be done before the 5 new hi-tech trains come into service.
She says: "In the short run they need to get four trains that work and are reliable and they can get back to running that service that people in Hull welcome - the fact we have that direct link with London. But they need to do it quickly."
