The project, in spite of its hefty price tag at between SEK 110-170 billion, would pay off and ultimately benefit the national economy, says the Transport Administration's Director General, Gunnar Malm.
"The largest socio-economic gain comes from shorter travel times. That's what really stands out in our calculations," Malm says.
The proposed project would be financed in part by considerably higher fees for rail operators to use the railway networks but also in part by local governments and regions.
The government will vote on a new national railway plan for the coming 10 years this spring.
