Take a look at the French download page for the route:
http://www.railsim-fr.com/forum/index.p ... owfile=832 . That page provides links to two UKTS packs and one RWA pack, all freeware, that are required if you want actual scenery for the route. By the way, the UKTS links provide downloads that are immediately available, so those not paying for "premium access" at UKTS do not have to wait in line. Don't be afraid of the "Telecharge" (can't make diacritical marks here) button -- that's French for "Download". The page linked to above also reveals that the DLC Donner Pass, American Assets, and European Assets packs are required.
By the way, if you install the route's English version, also available at the link given above, is already at version 1.1 and does not require a patch. To download it, first click the "Telecharger" button on the page linked above and then click the "Telecharge" button for "The Far North 1.1. rar.
And, finally, be sure that you have downloaded and installed everything listed and linked in the scenario pack's ReadMe file.
Dat's all, folks!
