Dear Pinocchio,
the route in question, Malmbanan, has already been build in its entirty for OpenRails.
It is part of a lager route network stretching from Norway and Finland down through Sweden and Denmark to Germany.
At present the route, hence denoted as "Route Scandinavia/Stockholmsrutten" has not been released yet. You can however follow our progress on our youtube channel where we have several enroute videos you can watch!
