It’s mid October at Glacier National Park in Montana’s rugged Rocky Mountains. Fall splendor has faded from the quaking aspens. Stands of larch have begun their annual transformation from green to yellow before their needles fall. The wind-swept open country to the east has taken on shades of brown while evidence of recent snows highlights the mountain peaks. Somewhere below all of this the Middle Fork of the Flathead River meanders through this wild and scenic country on its way west. The icy water knows an easy way through this forbidding mountain range and so does a railroad, for this place is Marias Pass. Today’s BNSF Railway continues to use this historic route through the Rockies forged over 100 years ago by the “Empire Builder” James J. Hill. Beginning at Whitefish, BNSF’s Hi Line Sub heads east through tunnels, trestles, wooden snow sheds and over the Continental Divide where mountain forests meet the high plains. Witness heavy trains and big power rolling through Montana’s Big Sky Country. Enjoy bonus scenes of SP Daylight steam locomotive #4449 in Montana and Idaho.
