Main line development project progresses in Tuusula area
The development of the railway section between Helsinki and Riihimäki will also be strongly visible in the Tuusula area next year. The Finnish Transport Infrastructure Agency reports that additional tracks and bridge work will be carried out between Purola and Jokela, among other things. The Jokela station area will be renovated.
Two additional tracks will be built between Purola and Nuppulinna. Currently, the final preload embankments are being built to reinforce and stabilise the soil, and space is being excavated for the new track. According to the Finnish Transport Infrastructure Agency, this work will be completed by the end of this year.
The actual construction of the additional tracks will begin in January. The project also includes the bridges and smaller ancillary works required for the additional tracks.
The project includes the renovation of the Tyynelä underpass, which is a culturally and historically valuable site from the first construction phase of the main railway line. The bridge work will be carried out in such a way that the Tyynelä underpass will remain unchanged.
The construction of the Purola–Nuppulinna section is part of a larger project, in which two additional tracks will be built between Purola and Jokela alongside the existing double track between 2024 and 2028.
Work will also begin between Nuppulinna and Jokela with the construction of preload embankments and electric railway pole foundations. This work will precede the later construction of additional tracks. Next year, foundation work for the eastern additional track will also be carried out in the area, and work will begin on the Huikko railway bridge.
Jokela station will be renovated in 2026–2028 with a new eastern platform, an updated underpass and measures to improve accessibility. The appearance of the area will also be changed by the Tuusula municipality’s Blennerintie street project, which will enable a connection between the Peltokaaren residential area and the centre of Jokela under the railway line. Blennerintie and the associated bridges will be built in cooperation with the municipality of Tuusula.
Bridge and electric railway work will be carried out in the Jokela station area next year. The Palojoen railway bridge and the Jokela underpass will be widened to accommodate additional tracks. In addition, construction of the Blennerintie bridge will begin.
The aim of the main line development project is to improve traffic flow and enable an increase in the number of train services on the section.
