Railway Line 272

Rail replacement on railway line No. 272, section Kluczbork – Poznań. The work package comprised modernisation of the railway line, track No. 1, from km 131.500 to km 133.918 and from km 150.160 to km 166.653. This primarily involved replacement of the rails over the track distance of 18.900 km (including replacement of the subgrade over the stretch of about 7.500 km and 10 crossovers at the stations in Jarocin and Sulęcinek), and the paving on 14 road-rail crossings. The platforms of the Sulęcinek and Jarocin stations were modernised. The same goes for the platforms of the Solec Wielkopolski stop, and 24 engineering devices over the section subject to modernisation. Redevelopment covered the traction network, automatic signalling system at road crossings, traffic control devices, and drainage.
