The I, P, K and N commuter trains will have altered schedules until 16 July due to rail yard improvement work.
K trains will not service the Central Railway Station in Helsinki. Instead, K trains will leave from and terminate in Pasila at all hours.
N trains will leave from and terminate in Pasila during the day. N trains will not run between Helsinki and Pasila during daytime.
I trains will run from Helsinki-Vantaa airport to Helsinki's Central Railway Station while P trains from the airport will terminate at Pasila.
At night I, P and N services, other commuter trains, and long-distance trains will run as usual.
Further service disruptions are expected later in the summer as maintenance projects continue until early August.
More information is available on the Finnish Transport Agency's website. From 16 July until 5 August a different set of diversions and alterations will be in force as track work switches to the western side of the rail yard.
