The railway line itself allows 250 km/h.
When the speed limit is raised above 200 km/h, it will be the fastest single-track railway in the world.
The trains will run at 180–200 km/h for the first few years, with a speed increase in the future.

The Transitio leasing company owned by the counties signed a contract in October 2008 to buy Alstom Coradia trains.
These trains were delivered in 2011, and they have a top speed of 180 km/h.
For long-distance trains from Stockholm, SJ runs X55 trains, with a top speed of 200 km/h.
So far the suppliers cannot guarantee winter characteristics above 200 km/h, since there is no experience operating at such speeds in the northern Swedish climate.
Still 2017, no trains run above 200 km/h since operator hasn't bought faster trains considering the only 200 km long distance allowing it and the fact that air travel is much faster Stockholm-Umeå anyway.

The Bothnia Line will also be the first line in Sweden equipped with the signalling system ERTMS (Level 2) and has been tested at 289 km/h on the southern part of the Bothnia Line.
Currently, Swedish signalling and its ATP safety system (ATC - Automatic Train Control) is only validated up to 210 km/h.

Parts of the  railway started to be used by freight trains on 16 October 2008, but with manual train protection control.

No Alstom train was delivered for the traffic opening in August 2010, since the delivery time is at least two years.
One train of the type Regina was rented from southern Sweden for the Umeå-Örnsköldsvik traffic, with a top speed of 200 km/h.
Traffic to and from Sundsvall started autumn 2012.
SJ ran the Stockholm-Narvik and Göteborg-Luleå night trains over Långsele-Mellansel-Örnsköldsvik-Umeå from August 2010, and from 2012 the shorter way Sundsvall-Kramfors-Umeå.
