[1] Around 1867, in the area of today's main railway station (Główny) a small, temporary passenger terminal Danzig Hohes Tor (Gdańsk Brama Wyżynna) was built.

On 2 January 1952 the SKM Trojmiasto suburban railway was opened, parallel to the existing line between Gdańsk and Gdynia.

Connecting tunnels enable access to the station building and tram stops, and contain shops, fast food bars, newsagents, and other kiosks.

The work aimed to remove changes made to the northern part of the building, replace windows and doors, update the passenger information system, security systems, introduce escalators, renewed lifts and an extension of the tunnel located to the east of the station.

The project also included the restoration and reintroduction of the details that had been lost or damaged as a result of World War II.

[5] In terms of the reconstruction of the railway infrastructure, PKP PLK plans to overhaul long-distance platforms 1 and 2 and the tunnels, replace lighting (preserving their historical shapes) and installation of passenger information systems, elevators and escalators.
