The line turns north-northeast, past a detector at MP 373.9 and the 11,126 ft. siding on the east side at Haskell (MP 373.7-371.4), and northeast at Saline Junction (MP 370.3), where Two Main Tracks (still CTC) begin, past additional track at Benton (MP 368.7), Sheridan Junction (MP 368.3), where MoPac lines once left to the west and southeast, a Rock Island line once left to the east, and a short line once headed north to Salem, the 5,405 ft. siding on the east side at Bauxite Junction (MP 365.3-364.2), where a spur to Bauxite heads away south and the speed limit drops to 70-60, and then to 60-50 at MP 363.3, as the line turns due east past additional track on the west side at Bryant (MP 362.7), north-northeast and then northeast again.
The speed limit returns to 75-60 at MP 361.1, there are crossovers at Alexander (MP 358.9), detectors at MP 358.6, the speed limit is 60-50 between MP 357.7 and 357.3, there is additional track at Arkansas Container Corporation (MP 357.1), on the east side at Enmar (MP 356.7) and at Arkansas Power and Light (MP 356.5), on the west side at AG (MP 356.3), where the speed limit drops to 70-60 as far as MP 355.9, at Mabelville (MP 355.0), and at Arkansas Power and Light (MP 353.4), and on the east side at Sterling Stores (MP 352.3).

The speed limit falls to 30 mph at MP 346.5, and the line turns northeast to the Little Rock Amtrak Station, on its own track on the east side between MP 345.9 and 345.6 with crossovers at both ends, during which the former Rock Island line from the west, along the south bank of the Arkansas River, trails in from the northwest, onto the main tracks across from the station. There was once a connector in the west quadrant and a loop in the north quadrant that crosses the main line at grade and entered the passenger station from the northeast.
