The construction of Kaisantunneli tunnel at Helsinki Central Railway Station is progressing – new platforms at tracks 1–3 to open on 19 August
New access routes to platforms 1–3 will be opened for passenger use at the Helsinki Central Railway Station on 19 August. The changes are due to the construction of the Kaisantunneli tunnel.
The Kaisantunneli tunnel is a tunnel for pedestrian and bicycle traffic that will be built under the railway yard, below the rails of the Central Railway Station. The ends of the tunnel will be located on Töölönlahdenkatu and the southwest corner of Kaisaniemenpuisto. The tunnel will streamline the east–west bicycle traffic considerably.
The work begun in the winter of 2020–2021. During the first phase of the project, fences were set up around tracks and platforms 1–3. Due to the ongoing temporary arrangements, trains arriving at tracks 1–3 will continue to stop approximately 50 meters north of the station. During the last week of September, test runs will be carried out in train traffic on tracks 1–3 and on tracks 10–13 on the Töölönlahti side. Once the test runs have been completed, it will be possible to relocate the stopping points for trains closer to the station.
Construction sites will remain at both ends of the tunnel with the purpose of finalizing the entrances and pavement work. All the underground concrete structures have already been molded, and the project is about to progress to the next phase in which lighting, painting and tiling work will begin inside the tunnel.
