The Tohoku Main Line links the eastern Japanese cities of Tokyo and Aomori on the main island, Honshu. The section of the route included here runs between Kitakami and Morioka; it is 48km in length and features twelve stations. The 701 Series commuter train is used on this route. I can't find anywhere that this route is a highspeed line so why is there a highspeed train in the addon?
Did you even read the full route description? Sounds like you only read the Tohoku Main Line, and not the Tohoku High Speed Line....
