Later proposals have been launched, and parliament has voted over it in 1954, 1978, 1984 and 1992; only the last being passed, but not followed up by funding, and Bane NOR has not allocated any date to start construction; detailed plans have however been produced.

Current plans are to build the line as double track for a speed of 250 km/h, permitting both freight and passenger trains through 22.5 tonne axle load and maximum 1.2% gradient; electrification would be at the Norwegian standard 15 kV  16.7 Hz AC.

[9] The Norwegian National Rail Administration has proposed a number of upgrades to the Bergen Line that would allow total travel time between the termini to reduce to four and a half hours.

The Ringerike Line is seen as the hallmark of this attempt, that was first launched by the director of NSB in 1954; sixty years later travel time remains at six and a half hours.

[14] Reducing travel time from Hønefoss to Oslo to 30 minutes would probably cause larger population growth in Ringerike.

Drammenbanen, that connected Sandvika to Oslo, was narrow gauge, as was most of the rest of the western network, including the Vestfold Line; hundreds of kilometers of railway would have to be converted.

Private financing would be provided through a dedicated limited company taking a surcharge on tickets, equal to the reduction in fare induced by the shorter line; within twenty years the debt would be covered.

[4] Director of the Rail Administration, Steinar Killi, stated in 2008 that the period 2010-19 would be a natural time for completion, but only if more overall funding for railway infrastructure is provided.

It would involve increasing from two to four lanes on the first 17 kilometres (11 mi) from Bjørum to Hvervenmoen, estimating to cost NOK 3.5 billion;[20] local politicians have suggested toll road financing.

[21] The Ministry of Transport and Communications started an evaluation of the Ringerike Line, carried out by the National Rail Administration, in 2006.
