Railway line 201 Kościerzyna – Somonino – Gdynia Główna (modernisation, electrification and second track) and Pomorska Kolej Metropolitalna line 248

Works contract "Odcinek A" of the project "Prace na odcinku Kościerzyna – Gdynia": about 27 km of line 201 plus 8 km of line 214, PLN 1.275 billion net (1.559 billion gross), signed on 12 December 2024 (gov.pl). Rail traffic on Kościerzyna – Somonino – Gdańsk Osowa has been stopped since 30 June 2025. PLK plans to resume trains Kościerzyna – Somonino in December 2027 and to finish all works on this stretch by the end of 2027. The drawn line follows the existing track (24.7 km measured from OpenStreetMap), shorter than the 27 km PLK figure; the sourced length is kept.

Works contract "Odcinek B", PLN 1,253,589,722.58 net (1.541 billion gross), for more than 28 km of line 201 with a second track and electrification, plus electrification of line 229 Glincz – Kartuzy. PLK gives the end of works as 2027 (without acceptance), passenger speeds up to 140 km/h after approvals. Traffic has been stopped since 30 June 2025; PLK plans to resume trains Somonino – Gdańsk Osowa in December 2026. The drawn line follows the existing track (25.8 km measured from OpenStreetMap), shorter than the PLK figure; the sourced length is kept.

PLK plans one contract for this section, with works in 2026–2031 and the whole project, including permits, to be completed by 2032. No tender, contractor or value is recorded. Length measured from OpenStreetMap geometry.

Built by Pomorska Kolej Metropolitalna S.A. (a Pomeranian Voivodeship company): a 17 km double-track line from Gdańsk Wrzeszcz plus a 1.4 km connector to line 201 towards Kościerzyna, joining it at Rębiechowo; trains then use line 201 to Gdynia Główna. Works contract PLN 716,136,838.06 including VAT. Wikipedia gives the total project as PLN 907 million net including PLN 186.5 million of land, and PLN 949 million with the Gdańsk Osowa station and two Gdynia stops; these cover more than the line and are not recorded as cost. Wikipedia also records a PLN 106 million connection works contract won in 2014 by a Rubau-led consortium. PKM's own 2013 release gives the contract as PLN 582.2 million net (716.3 million gross).
