The railways in Stockholm-Mälardalen are continuously being maintained and improved. This means that parts of the railway network periodically need to be completely, or partially shut down.

The information about planned track work is preliminary, exactly how the trains will run during this time is determined in more detail closer to that period. 

Search your trip in the app Mälardalstrafik and on Mälardalstrafik.se to see the updated timetable.

Please note that travel time may be longer than usual when trains are replaced by buses.
