Sick staff and problems with a new planning system that takes time to solve continue to cause train problems.
Several scheduled departures will be canceled from Monday until April.
It is above all the Uppsala-Stockholm section that is affected, where the number of departures decreases by about ten departures a day, including Mälartåg's traffic.
- The number of departures between Uppsala and Stockholm is still more than in, for example, October last year.
In December, we made an offensive investment together with Mälartåg and based on that we have to reduce traffic because we have a lot of staff away, says Jan Kyrk, business manager at SJ.
"SJ must steer this"
This week, Mälartåg has also had to cancel departures due to sick leave among train drivers and train hosts, and several passengers that SVT spoke to testify about the train noise.
- When I went before, first the train between Uppsala and Stockholm was delayed, then another train was delayed so I missed a connecting bus.
Then I had to take a taxi and then my father-in-law had to pick me up, so it got a little awkward.
You can not have it this way, SJ can control this, says Sebastian Ibstedt.
