At Red Pass Junction, Canadian National's Prince Rupert line diverges from the Vancouver bound mainline and the two closely parallel each other on different elevations for approximately 20 miles. On reaching the Rocky Mountain Trench, they go off in opposite directions with the former Grand Trunk Pacific line heading northwest towards Prince George and Prince Rupert. This eastbound freight on the north line is seen near Tete Jaune with mountains of the Premier Range in the background.
