The station features two island platforms, of which one functions as the regional commuter SKM stop and the other for long-distance services.

In 1909 Sopot had direct train connections from Berlin, Bydgoszcz, Konigsberg, St. Petersburg, Poznan, Szczecin, Torun and Warsaw.

In 1912 the first work began for the construction of a separate pair of tracks for urban traffic from Gdańsk Główny towards Sopot.

[3] Identical or similar stations were built in Gdańsk-Wrzeszcz, Gdańsk Oliwa, Gdynia Chylonia, Reda, Wejherowo and probably in Lębork.

In 1945, the original station building was burned down by Soviet troops advancing along the railway tracks on Danzig (Gdansk) from Gdynia in the northwest.

The functionalist 1970s ticket building was torn down in 2013 to make way for a complete redevelopment of the entire station and its surrounding area.
