Rapid Railway of Gdańsk, Gdynia and Sopot (SKM) is very similar to a typical German S-Bahn, so it can be classified as a metro-like line. Line S1 uses separate tracks along most of its route and has a dense interval (trains every 7-8 min. during rush hours and every 10 min. during the rest of the day; 10-20 min at weekends).

The line starts at Gdańsk Glowny (Gdansk main railway station) and runs on dedicated tracks through Sopot, Gdynia up to Rumia station. Then it shares tracks with other long distance and suburban trains. Total length of the line is approx. 46 km and it is the only real S-Bahn system in Poland.

Trains used are the typical Polish suburban train sets EN57 or newer. During recent years some trains were modernised. SKM train run Mon-Fri every 7-8 minutes during rush hours, and every 10 minutes at other times; Saturday & Sunday - every 10-20 minutes.

Gdańsk also has a quite well developed tram network, but trams don't go to the neighbouring towns of Sopot and Gdynia.
