Construction work on additional tracks begins between Purola and Nuppulinna
The Finnish Transport Infrastructure Agencyu0026#x27;s Helsinki–Riihimäki railway project will see the construction of additional tracks between Purola and Nuppulinna begin in January 2026. The work is expected to continue until the end of 2028.
Work will begin in January with the construction of two new tracks between Purola and Nuppulinna, alongside the existing double track. The work includes, among other things, track foundation, substructure and superstructure work, electric track, high-voltage and lighting work, as well as switch installations and noise barrier construction. The work phase will also include the construction of bridges required for the additional tracks. Kreate Oy is responsible for the construction of the additional tracks between Purola and Nuppulinna.
“We will begin preparatory work in January and move on to actual construction in February. Construction will begin at several different sites within the contract area. We will provide separate information about noisy work and any temporary traffic arrangements during construction well in advance of the start of work,” says Riitta Parviainen, project manager at the Finnish Transport Infrastructure Agency.
Preload structures and excavation to be completed in January
Preparations for the construction of additional tracks between Purola and Nuppulinna have been underway since autumn 2024. The preload embankments that reinforce the soil and the excavations for the additional tracks will be completed in January.
“The completion of the preload embankments and excavations will help us stay on schedule. We will be able to start building the additional tracks quickly,” Parviainen continues.
Part of a larger whole
The construction of the section between Purola and Nuppulinna is part of the second phase of the Helsinki–Riihimäki railway project, in which two additional tracks will be built between Purola and Jokela alongside the existing double track between 2024 and 2028. The additional tracks will improve the capacity and reliability of the main line, which will facilitate the implementation of timetables for local, long-distance and freight traffic throughout the entire section.
