Sweden's already hard-pressed train travelers are weighed down by new burdens.Mälartåg basically cancels all departures between Uppsala and Gävle on Sunday due to holidays and sick leave.At the same time, the disturbances of recent days continue in Närke and Jämtland.Usually, one Mälartåg per hour goes from Uppsala to Gävle, and vice versa. But due to lack of staff, most trains are cancelled.- This is due to staff shortages due to vacations and cases of illness. We don't have enough train drivers or train attendants on the routes, says Rebecca Lundin who is a press spokesperson at the train operator MTR.At the moment, she can only say with certainty that Sunday's traffic will be affected.However, MTR has not yet made a decision on how to bring in more staff. Lundin says that they are in the process of reviewing the options available.- We will try to solve next week's traffic, hopefully we will be in a better position then."Short notice"TT: Is it possible to bring in personnel from other parts of the country?- It is difficult to do it at short notice. It would only be relevant later in the week if the situation does not look better.More of MTR's routes are also affected by staff shortages, although not to the same extent as the departures between Uppsala and Gävle.The routes Norrköping–Nyköping–Stockholm and Örebro–Eskilstuna–Stockholm–Uppsala also have canceled departures on Sunday.
