The Bothnia Line ends near the Höga Kusten Airport at the existing Ådalen Line, which runs Långsele–Kramfors–Härnösand–Sundsvall.
The distance from the connection to Sundsvall is 101 km (63 mi).
This railway was built from 1890–1925, and is rather curvy and in poor condition.
From 2003 to 2012, the Ådalen Line was improved along the existing route to allow higher speeds than before, with a maximum speed of 150 km/h (93 mph).
The improvements included new rails, new catenary, a new signalling system (ERTMS) and better and fewer road crossings.
A few parts of it north of Härnösand (totalling 30 km (19 mi)) were replaced with a new route, built to the same standard as the Bothnia Line, with a maximum speed of 200 km/h (120 mph).
The reason for keeping most of the existing route is that the advantage of building a new railway is smaller when there already is a railway, but the costs for a new railway would be the same as if there was no railway, which is the case along the Bothnia Line.
The total improvement cost for the Ådalen Line was 6 billion SEK.
