Grenland Line

The Grenland Line (Norwegian: Grenlandsbanen) is a proposed high-speed railway line that would connect Grenland and Gjerstad in Norway. Specifically, the line would connect the Sørlandet Line at Skorstøl to the Vestfold Line at either Porsgrunn or Skien, allowing passenger trains from Stavanger and Kristiansand to be routed on the Vestfold Line through Grenland and Vestfold. The Grenland Line is proposed built with double track and with a speed of 250 km/h (160 mph). Three routes have been proposed, varying in length between 64 and 70 kilometers (40 and 43 mi). A prerequisite is that the Vestfold Line be upgraded to double track and high-speed, a process that started in the mid-1990s and which is scheduled for completion in 2032. A completion of the upgraded Vestfold Line and the Grenland Line would reduce travel time for passenger trains between Gjerstad and Oslo by about 70 minutes.
