How traffic is affected
On Monday, trains will run on a single track between Knivsta and Uppsala. This means fewer departures, a risk of crowding, and slightly longer travel times.
Important to know
- Since trains are operating on a single track, delays of up to 15 minutes per departure may occur.
- If you have a Mälartåg single ticket or a Movingo period ticket, you can also travel with SL commuter trains between Stockholm C and Uppsala.

Train service schedule
- Once per hour: Mälartåg between Stockholm and Uppsala via Märsta and Knivsta, in both directions (Mälartåg train numbers 8xx).
- Once per hour: SL commuter trains between Stockholm and Uppsala. Other departures turn around at Upplands Väsby (commuter train numbers 22xx).
- Mälartåg from Örebro–Eskilstuna that usually continue to Uppsala (Mälartåg train numbers 9xx) will terminate in Stockholm. If you’re traveling onward to Uppsala, you’ll need to change trains at Stockholm C.
