Länsimetro, superstructure and conductor rail system contract

The superstructure contract includes the construction of the metro track in tunnels. The contract consists of the supply of the backing layer of crushed stone and the installation of railway sleepers, tracks and switches. The purchase and installation of ground-borne noise insulation is also part of the superstructure contract. After installation, the rails are welded together to form a continuous rail, and the track is supported several times, ensuring a soft and smooth metro ride for future passengers. The contract includes the construction of the superstructure for 17.2 kilometres. In total, 42 switches will be installed, and a conductor rail system will be built for the entire work area.
