The line heads north, with what appears to be a 10 mph speed limit, past a grade crossing, a wooded area, a dirt road grade crossing, where the dirt road then comes alongside to the west, and then ends where there is additional track on the west side, a dirt road grade crossing, a grade crossing at 61st Street (Coal Main), a track trailing in on the west side, two road bridges overhead, a line edging away on the east side, the location of the former passenger station on the east side of the line at Superior (MP 5.4), an (erstwhile?) angled flat crossing with the former GN line, and the wye junctions with the east-west line at LST&T Junction (MP 3.5), including a connector directly ahead into the Midwest Energy Terminal, which makes a flat crossing with the east-west line.

A Missabe line used to bridge overhead onto Dock 5 (with a still-extant steel trestle), there is a pedestrian bridge overhead, and another Missabe line, that still goes onto Dock 6, bridges overhead on a steel trestle, there is a dirt road grade crossing, a street alongside to the southeast, the junction with a north quadrant connector from that Missabe line at Missabe Junction, a road bridge overhead, water alongside to the southeast, dual road bridges overhead (I-535), two road ramps overhead, two tracks curving away to the southeast to form a wye at 20th Avenue, where the twenty-four track Rice's Point Yard is to the southeast at right angles to the main line, a road bridge overhead, the other leg of the wye (Also two tracks) on the southeast side, a pedestrian bridge overhead, huge piles of limestone to the southeast, the yard at Garfield Avenue (MP 1.6) on the southeast side, a street alongside to the northwest, road ramps overhead, two tracks on the northwest side into a maintenance shed at the museum, and the former Union Passenger Station at Duluth (MP 2.9/150.1), now the Lake Superior Railroad Museum, with a stub end platform track on the northwest side, with brick platform and umbrella shed to its northwest, alongside the original station buildings now housing the museum's collection (with the waiting rooms, etc., in a building northwest of that), where the North Shore Scenic Railroad continues ahead, southeast of the museum, and a road bridge overhead just east of the museum buildings.
