The first railway station to be built in Trondheim was located at Kalvskinnet, to serve the narrow gauge Trondhjem–Støren Line railway that was completed in 1864.
The station was designed by Georg Andreas Bull, and still exists as a synagogue.
In 1877 the state and city made an agreement to build a new station at Brattøra to serve the new Meråker Line that was being built to Sweden.
Brattøra was chosen because it was located directly beside the port, and would allow direct transshipment from ships to the railway of both goods and passengers.
The station would become the main station for both railways; this caused a major protest among the local population, who felt it was necessary to have two terminal stations, one for each line, and the city brought the matter before the courts—the case was settled in 1895 in favor of one station.
The lack of planning and coordination between the two lines made the new station a large budget cost for the Meråker Line; and described as one of few exceptions to the small-and-cheap policy dominating the state railways i Norway at the time.

Two lots were sold to the state railways from the city, allowing the building of two station buildings, the eastern cargo building for the Meråker Line and the western for Røros Line.
The main station in the east served all passenger trains, and was designed by the architect Balthazar Lange.
A new route for Røros Line was built from Sluppen to Skansen, along the west side of Nidelva, and the old station taken into disuse after the Røros Line reached the central station on 24 June 1884.
To solve the challenge of the break-of-gauge, the entire station area had dual gauge with both 1,435 mm (4 ft 8 ¹⁄₂ in) and 1,067 mm (3 ft 6 in).

The station at Brattøra has had four names, following the name changes of the city.
It was opened as Throndhjem, changed in 1894 to Trondhjem, on 1 January 1930 to Nidaros and to Trondheim on 6 March 1931.
The station at Brattøra is physically divided in two parts by the bridge over Ravnkloa.
From 1884, the western part was officially called Throndhjem V and the eastern part Throndhjem Ø. The freight station for the Røros Line was located at Throndhjem V, while the passenger station for both lines was located at Throndhjem Ø, just like today.
While there were two stations in 1882–84, they were 'probably' referred to as Brattøra and Kalvskinnet.

On 23 April 1888 a landslide hit the station, with 180 metres (590 ft) of track—three wide and including the main Rørosbanen line—was washed into the sea.
The slide was caused by the seabed sinking about seven meters, and it was followed by several smaller slides.
