Rail commuters are being warned of cancellations on Hull Trains this week because of routine maintenance.
Half a dozen services have been either cancelled or altered today and tomorrow.
Hull Trains say they hope to be back to normal again next week.
A spokesman says: "Having had a period of improved performance in the last few weeks, one of our trains has had to go in for some routine maintenance and we are operating a slightly reduced timetable at the moment. We anticipate being back to normal again next week."
