Track work related to the Finnish Transport Infrastructure Agency’s Espoo Rail Line project will cause disruptions to train services on the Coastal Line in spring, summer and autumn this year. In autumn, services will be disrupted on five weekends in September and October. Two-day disruptions from Saturday morning to Monday morning will take place on 5–7 September, 19–21 September and 3–5 October. One-day disruptions will take place on Sundays 13 September and 27 September. Train services on the Coastal Line were disrupted for five weeks starting on 23 June. In spring, disruptions lasting about a day occurred mainly on weekends in May.
During the service disruptions in autumn, A trains will run between Helsinki and Leppävaara every 10 minutes at peak times. All up-to-date timetables are available in the Journey Planner.
The Finnish Transport Infrastructure Agency’s Espoo Rail Line Project involves constructing two new tracks between Leppävaara and Kauklahti. Once completed, the rail link will improve the punctuality of commuter train services in Kirkkonummi and Espoo as well as the punctuality of long-distance train services in the direction of Turku. In addition, improvements are being made to Kilo, Kera, Kaunainen, Koivuhovi, Tuomarila and Kauklahti stations. The project started in spring 2021 and is scheduled to be completed in 2029.
