From Cecil Junction (MP 993.6), legal meeting place of the Central Pacific and Union Pacific, where the speed limit is 55 mph and the OSL trails in from the north, there are crossovers onto Two Main Tracks, CTC, with speed limit 30 mph, a bridge across the Ogden River, an erstwhile wye on the west side, an erstwhile flat crossing to the D&RGW terminal station, and the still-extant south leg of the wye where the rump of the former D&RGW trails in, to Ogden (MP 993.0), where the freight yards are on the west side of the line, and the former Ogden Union Depot, now a museum, is on the east side of the residual passenger platforms with their umbrella sheds.
The line continues south, past the wye on the west side with the former OSL line south to Salt Lake City and then the loop line off on that side that curves around to join that line, as the eastward main line, still heading south, two Main Tracks, CTC, speed limit 40 mph, passes 31st Street (MP 991.5), where the former Bamberger Railroad once crossed at grade, comes alongside the east bank of the Weber River, and passes crossovers at Riverdale (MP 989.7), north end of Riverdale Yard on the west side of the line, and turns east-southeast to the south end of the yard at the crossovers at East Riverdale (MP 988.6), where the speed limit is 60 mph, along the (now) north bank of the Weber River.

The tracks come back together again, with a road grade crossing, at the 4,662 ft. center siding at Wahsatch (MP 927.1), passing detectors at MP 925.6, and turning east into Wyoming, where the landscape opens out somewhat, past an eastward hold signal at MP 919.2, where the speed limit is 45 mph, and crossovers and a 9,064 ft. siding on the north side at Evanston (MP 917.2), where the roundhouse and shop complex are now owned by the city, before turning south-southeast, past a westward hold signal at MP 915.8, and then east-southeast at the 1,501 ft. center siding at Millis (MP 912.5), where an earlier version of the line (1868-1901) continued south-southeast and the speed limit on today's line is 60 mph, on a ledge on the northern hillside, past a detector on track 2 at MP 910.6, south past a detector on track 1 at MP 909.1, east, with a mountain to the west and a road on the hillside to the north, and then northeast to crossovers at the summit at Altamont (MP 904.8), in a broad valley with bluffs on either side, where the speed limit is 45 mph and Two Main Tracks, CTC, begin, with the tracks separating and at different levels past 6,706 ft.

The line continues curvily northeast, past crossovers and a 689 ft. center siding along the north side of the valley at Spring Valley (MP 897.6), a deck girder bridge over a road, and Ragan, the earlier line rejoins from the east side as the line heads north past a detector on track 1 at MP 890.5 and the crossovers and 1,079 ft. center siding at LeRoy (also MP 890.5), where the speed limit is 60 mph, there are red bluffs along the north side of the line, a dirt road grade crossing, and a dirt road along the south side of the line from LeRoy to Carter, the 6,378 ft. center siding at Bridger (MP 885.6) and a detector on track 1 at MP 894.1, where the speed limit is 50 mph, turning east past Antelope, an eastward hold signal at MP 876.3, where the speed limit has risen to 70 mph, and a westward hold signal at MP 875.6, turning northeast past the 6,522 ft. center siding at Carter (MP 875.4), Elkhurst, a detector on track 2 at MP 867.7, where the speed limit is 60 mph, crossovers at Hampton (MP 866.2), where the speed limit is 70 mph, as the line turns east, northeast again past Church Buttes, east again past a detector on track 1 at MP 854.7, and a 6,040 ft. center siding at Verne (MP 854.0), and east-northeast to the wye junction and crossovers at Granger (MP 846.5), where the former Oregon Short Line trails in from the northwest, there is a spur on the south side, a signal bridge west of the junction over the 2MT, a dirt road grade crossing on the Overland Route, west of the junction (and the same road over the OSL just further west), and there is a 13,456 ft. siding on the north side of the line to the crossovers at East Granger (MP 844.0).
