In 1910, the Parliament of Norway announced a competition for the redesign of the station since it had been decided that the Dovre Line would be built to Trondheim, including the line from Støren to Trondheim being converted to standard gauge.
On 18 August 1913 construction of a new station and port was started.
Traffic had increased to the limits of capacity; there were too few tracks and too small cargo buildings.
By 1912 some freight cars were stopping at Hommelvik and Storlien; a counting showed 900 cars at the station.
The construction removed a gap filled by the canal between the two stations—filling up the canal in the process.
Instead the 92 metres (302 ft) Skansen Bridge was built on the west side of the station, along with a double track to Marienborg where the new depot would be located.
The main station building designed by Lange remained the passenger and administration building, with the conversion of the smaller, western one into cargo facilities.

The amount of trackage for cargo was increased, with a wide section of land mass being filled into the sea to create a larger rail and port facility at Brattøra, though the filling of a large part of the seabed to create artificial land.
The railways allowed the transshipment of cargo from ships from Northern Norway to rail, as well as from rail from Central Sweden to ships to the British Isles.
The port was supplemented by a new line to Ilsvika would allow the loading of ore there.
The suggestion to build double track to Leangen was dropped.

While the original plans for the Dovre Line involved completion in 1916, it was not until 1921 the first train could travel from Oslo to Trondheim via Dovre, mostly due to the First World War.
The new depot opened in 1916, and in 1917 the double track and dual gauge to Marienborg as well as the new freight terminal was finished.
Instead of using one track for each direction on the double track, the Dovre Line would use the one line while the other would be used for transport from the station to the depot.
Skansen Bridge opened on 22 March 1918.
In 1922, Norsk Spisevognselskap established a kiosk, and on 1 October 1925, they took over the station restaurant.

The main building designed by Lange is in historicism and was originally built in two stories in brick.
A third was added in the 1950s, some with some of the original feel being lost in the addition, since it was not stylistically true.
In 1965 two annexes were built, one on each side and in two stories.
The western was used for offices and the other as part of the waiting area—these were both in line with the historicist style.
They replaced a cargo expedition and a restaurant building, respectively.
In 1995 the bus station was moved from the city center at Leüthenhaven to the central station, and the eastern annex was razed in favor of a postmodernistic glass and concrete building.
In addition to the bus station it features and extension of the waiting area, offices, a restaurant and a parking lot.
