History
The Voss Line

The first documented proposal for building a railway between Norway's two largest cities was announced by
Andreas Tanberg Gløersen on 24 August 1871 in ''
Bergensposten''. The forest supervisor in Voss suggested building the railway via Voss and

, connecting with the
Krøderen Line. In 1866, Gløersen had come up with the idea of the
Jæren Line. Within days of his proposal for the Bergen Line, the city council expressed support for the suggestion. In 1872, the railway director
Carl Abraham Pihl and two engineers went on a survey tour along suggested line. At the time it was common that proposals for railways came from local initiative, and that local municipalities and private investors would then pay for about 20% of the investments, the state covering the rest, mostly through
foreign debt.
Political processes
On 20 October 1871 two engineers traversed the two possible routes from Bergen to Voss; the one via
Fana,
Os and

Sørfjord. Though covering a less populated area, the latter would be cheaper to build, and have less elevation. A railway committee was created on 25 January 1872 with a limited mandate, which was expanded on 20 December. At the same time there was a dispute between the
Ministry of Labour and Pihl about whether to prioritize the Bergen Line, but in July 1872 surveys were performed in person by Pihl and two engineers, and their report was positive. At the same time he launched the idea of a branch line up

By 1873, an agreement had been reached as to the
right-of-way to Voss, but not onwards towards Oslo. On 13 January 1874, the Bergen city council started issuing stock for the Voss Line, to begin with 400,000
Norwegian speciedaler (NOK 1.6 million) were issued. In the
1873 parliamentary election the railway supporter
Peter Jebsen was elected, spending the next few years furiously defending the railway.

chose to not issue new railway projects in the 1874 session, and instead adopt a complete plan for all railway construction in the country—to be proposed by a committee. When the committee reported on 20 March 1875, the Voss Line was not included since it could not show a higher profitability than 1%. During the 1875 session there was not a majority for the Voss Line, partially due to the lack of capital available from local investors. This was based on a claim from
Johan Jørgen Schwartz, the chairman of the committee, that the investment costs were underestimated. This was countered by
Nils Henrik Bruun
Nils Henrik Bruun (1832–1916) was a Norway, Norwegian engineer.
Biography
Nils Henrik Bruun was born in Tønsberg in 1832. Educated at Chalmers University of Technology, Chalmers in Gothenburg, and in Germany, Bruun moved to Bergen in 1863 wher ...
, a constructor from Bergen, who was willing to construct all tunnels on the railway for less than the budgeted sum. When Jebsen in addition was willing to act as personal guarantee for Bruun in case of his death, the majority in the parliament shifted. On 9 June 1875 parliament voted with 61 against 42 to build the Voss Line.
Construction
The Voss Line was built with narrow gauge, . The first parts of the construction started in December 1875, while the largest part started in March 1876. During the winter the engineers had done the last finesses on the plans. At any given time at least 800 men worked on construction, and at the peak 1,800 men were employed. They worked 12 hours per day, for which they had a daily wage of NOK 2.55, the highest wage for
navvies in the country. To a large extent the labor came from Sweden, who had just finished the
Norway/Vänern Line and had an excess of skilled labor for construction. This import of labor had the effect of pumping money into the local economy, and several taverns were built along the line. There were some accidents, and several deaths among the workers.
The construction work was finished in 1882 and some test services began, though not scheduled until the spring of 1883. Official opening commenced on 11 July 1883. Many of the navvies settled on Vossebanen after construction, and started working for the

Construction of the Bergen Line

. Parliament was not willing to give more money to railways, and the country had to make do with a transport plan launched in 1886 that did not follow up with any funding. On 1 March 1894 parliament after five days of debate chose, with 60 against 53 votes, to build the Bergen Line. Several different routes had been proposed, including over
Krøderen, or down
Numedal

(where the
Numedal Line would later be built). In the end Hallingdal was chosen, connecting to Hønefoss and on to Oslo via Sandvika. To save costs a preliminary line would connect Hønefoss to
Roa with the branch
Roa–Hønefoss Line. The final line would run along the
Gjøvik Line to Oslo. The line would also connect to the rest of the network via the
Randsfjorden Line at Hønefoss.
Local financing was ready within a year, yet it took six years to survey the line properly, and construction start had to wait until 1901. Construction started with the building of roads to get in supplies to the construction sites, completed in 1902. The construction was exceptionally challenging, taking place at high altitudes in a region without roads and with a climate that saw many metres of snow in the winter and temperatures far below freezing. 113 tunnels, totaling had to be built; the longest, the
Gravehalsen Tunnel, alone costing NOK 3 million and was the longest tunnel north of the Alps. It took six years to build, and had to be excavated manually through solid

. Laying of track was started in 1906, and in 1907 the two groups, both having started at their own end, met at Ustaoset. A small celebration was held at the spot (see image).
It had been decided that the Bergen Line, unlike the Voss Line, was to be built with
standard gauge

. So, the newly laid line from Bergen to Voss had to be converted in time for the opening of the Bergen Line. This was especially challenging because of the continuous traffic on the line, with 36 departures per day to Nesttun, six to Garnes and four to Voss. In preparation a few curves had to be straightened, the tunnels widened and the bridges strengthened. On the night of 10–11 August 1904 all the track was changed and in the morning the trains could operate on standard gauge to Voss.
The first services started on 1 July 1907 from Voss to
Myrdal. An official opening train attempted to cross part of the line to
Gulsvik on 9 December 1907, but got stuck in heavy snow and had to return. The railway had to close and it took one and a half months to clear it of snow. Even a

Drammen Line via the
Krøder Line with ship over
Krøderen to Gulsvik. The first scheduled train from
Oslo West Station to Bergen departed on 10 June 1908.
On 25 November 1909 a train en route from Bergen rolled into
Oslo Østbanestasjon, and two days later the railway was officially opened at Voss.

. In 1939 a plan for national electrification was launched, and the Voss Line was top priority. But the breakout of World War II set the plans back, and not until the 1950s was it again possible to afford such investments. Vossebanen took electric traction into use on 2 July 1954.
The electricity is supplied via an overhead line.
In 1952 a new plan was launched by parliament to electrify of railway, with the line from Voss to Hønefoss prioritized fourth. This section of the line was considered "difficult" because of tight curves, difficult track alignment; and also that the

s with electric or
diesel traction. Since electrification was not imminent, the
NSB introduced diesel traction on the Bergen Line in 1958. The line was electrified in four stages, from Roa to Hønefoss on 1 February 1961, from Hønefoss to Ål on 1 December 1962, from Ål to Ustaoset on 15 December 1963 and finally from Ustaoset to Voss on 7 December 1964.
As the point of electrification moved across the mountain, so did the point NSB changed locomotive on the train. The new locomotive
El 13 was put into service on the electric parts. The electrification cost NOK 143 million.
The express trains have as one of the main lines always been allocated the newest locomotives by NSB. When the

Arna station had to be constructed adjacent to the tunnel mouth. This also opened in May 1964. The opening of this tunnel meant that it replaced part of the original and that part was no longer needed as a main line. It became a heritage line: the

It was to be constructed in a number of main contracts: the first was boring the single-bore ) tunnel, which began in January 2016, and was completed on 29 August 2017. The second was the installation of the infrastructure: installing the rails in the form of a cast

Because of space constraints at Arna station, due to the need to move trains between platforms within the station, the new tunnel has a double portal at Arna station and is double-tracked for a short distance, before combining into a single running track.

awarded a contract to Grupo Azvi to refurbish the old 1960s tunnel, with work due to start in February 2021 and due to finish in June 2023.
The requirement is do this refurbishment without lifting the existing rail track. As part of this work it will be fire-proofed; two diagonal tunnels at the Arna end are to be blasted between the old and the new tunnels to allow trains to switch from one to the other; as well as blasting 16 other common interconnections for escape and for installing infrastructure.
Double running will only be achieved when the refurbishment of the old 1960s tunnel is complete; and the second half of Arna station, linked to the old tunnel has been rebuilt. To obtain the full benefit of this work, it is intended to double the track all the way from the tunnel to Bergen.

Drammen Line and the Randsfjord Line to Hønefoss. This allows the trains to pass through more densely populated areas and on trackage with more capacity. However, the change of route actually increased the length between the two termini by . But the better track standard via Drammen results in about the same travel time. Freight trains still goes via Roa.

and the station itself. Part of the snow tunnel caught fire in 1948 and spread to the station; and, there was another fire in the snow tunnel in 1953. Yet another fire in 1960, this time external to the tunnel, caused the loss of the snow tunnel; the railway station, which was rebuilt in 1970; and the station hotel, which was not replaced.
On 16 June 2011, a possible welding accident may have been the "cause behind a fire" in the snow tunnel at

Express trains operated by NSB have always been the primary passenger service on Bergensbanen. Passenger trains follow the Drammen Line and the Asker Line to Drammen, before heading north to Hønefoss on the Randsfjord Line. The express trains offer both transport from villages along the line to either Bergen or Oslo, as well travel between Norway's two largest cities. Expresses are

Future propositions
A call for more investment in railways
In 2002 the Norwegian National Rail Administration warned that lack of funding might lead to a closure of all long-distance passenger trains in Norway, including the Bergen Line.
Torild Skogsholm,
Minister of Transport and Communications assured that it was not the government's policy to close railway lines. In 2004 the
Progress Party suggested closing down the railway line and replacing it with a motorway between Bergen and Oslo, arguing that the railway was unprofitable, and that bus transport was cheaper while easier truck transport would aid business. Other political parties rejected the proposal pointing out the better environmental performance of the railway and that the railway transports large volumes of freight.
Upgrades
The original plans for Bergensbanen from 1894 included the construction of a new line—the
Ringerike Line—from Hønefoss to
Sandvika
Sandvika () is the administrative centre of the municipality of Bærum in Norway. It was declared a List of cities in Norway, city by the municipal council (Norway), municipal council in Bærum on 4 June 2003.

just west of Oslo. This line would reduce the distance on Bergensbanen by and 50 minutes travel time. There has been a continual decision to build this railway line, but it has never received any funding. These plans were discussed more after 2000, and a detailed plan has been done. Combined with other improvements totaling investments of NOK 7 billion, travel time could be reduced to four and a half hours. The project is scheduled to be started in 2024, and finished around 2030, now at a cost of 36 billion NOK including 20 km motorway.
Arne-Stanghelle Joint Project
In January 2025, a contract was put out to tender for a project constructing a series of new rail and road tunnels near the western end of the line. Starting north-east of Bergen at Arna, the proposed route continues through a newly constructed station at Vaksdal, to finally rejoin the existing alignment at Stanghelle. The project would bypass the existing stretch of winding single-track rail skirting the South-Eastern shore of
Veafjorden, with around of new double-track rail and parallel road tunnels. The new tunnel would support train speed up to 200 km/h, reducing travel time between Arna and Stanghelle stations from an average of 28 minutes to under 14 minutes. The Arne-Stanghelle Joint Project is funded by Bane NOR and the

as part of the 2025-2036 Norwegian
National Transport Plan, and is projected to take 12 to 14 years to complete, with an initial forecast budget of 40 billion kroner.
High-speed rail
Several suggestions for high-speed rail from Oslo to Bergen have been launched. Preliminary studies performed for the National Rail Administration suggested a positive
cost-benefit ratios on building high-speed rail from Oslo to Bergen. The most suitable route would approximately follow the existing route (but with a new tunnel Oslo–Hønefoss). Oslo–Trondheim and Oslo–Halden are assumed to be built earlier because of lower cost. Two lobbyist suggestions to the route have also been launched. The one involves a "high-speed ring" from Oslo, via Numedal to Geilo, then following Bergensbanen to Bergen and continuing south to

.
Norsk Bane has launched the idea of building a common line from Oslo to
Haukeli and then branching off to Bergen and Stavanger.
Such long-distance high-speed railways are not included in the preliminary long-term plan for 2010–2040, and it is likely that railways Hamar–Trondheim and Drammen–Kristansand will be built first since they are easier to build. It is likely that a high-speed railway to Bergen will be built sometime in the period 2030–2060.
