The eight-station double-track line branches off the Gdansk – Gdynia line west of Gdansk Wrzeszcz station, turning south through Bretowo and Jasien before crossing the S6 highway to reach a park-and-ride station at Matarnia. From here it continues west to Port Lotniczy, which will serve the airport, before joining the existing Koscierzyna – Gdynia line at a triangular junction south of Osowa station.
A 15-minute interval service operates over the new line at peak times with a journey time of 18 minutes between Gdansk Wrzeszcz and the airport station at Port Lotniczy. Services are operated by a fleet of 10 Pesa Bydgoszcz DMUs ordered by PKM last year at a cost of €27.5m.
The line is part of the SKM Tricity regional rail network and is expected to carry around 12.5 million passengers per year.
