Construction of the Kaisa Tunnel to begin – Changes for passengers using Helsinki Central Railway Station from January 2021
The construction of Kaisa Tunnel, a pedestrian and cycle tunnel from Töölönlahdenkatu to Kaisaniemi Park, will affect passengers using Helsinki Central Railway Station from Sunday 3 January 2021. The stopping points for trains on platforms 18 and 19 on the Töölönlahti side of the station will change.
Works on the site will begin at the start of 2021 on the Töölönlahdenkatu side of the station. The tunnel is constructed by the City of Helsinki.
The stopping points for trains on platforms 18 and 19 on the Töölönlahti side of the station will change
- From Sunday 3 January 9.15am, trains will stop about 100 meters further up the track, away from the station, on platforms 18 and 19. Consequently, walking distances will increase. The platforms are served by I, P and A trains.
Fencing of the construction site, phase 1 (at the west end)
- The fencing works will begin on 4 January.
- Fencing will be erected between Töölönlahdenkatu and platform 19. Access to platform 19 will be via stairs at the corner of Töölönlahdenkatu 3. At this point, access to the station from platform 19 will remain open.
- From Monday 4 January, step-free access from Töölönlahdenkatu to the platforms and the station will be via Elielinaukio.
Fencing of the construction site, phase 2 (at the west end)
- The construction site will expand in January. The end of platform 19 (on the station side) will be fenced off and a fence will be erected on platforms 17 and 18.
- A pedestrian route will be built over tracks 18 and 19 in the end of January.
The figure below shows routes to platforms 17, 18 and 19 at the end of January. The fencing and signs will direct passengers. Soil removal work will begin once the fencing is in place, to be followed by excavation.
