The Little Rock Amtrak Station is 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. The line crosses the Arkansas River to Arkansas River (MP 345.4), where the Cotton Belt line once headed east along the north bank of the river, and Hill (MP 345.1), where the Mississippi & Little Rock once headed east, turning east where the Jenks Diesel Shop is on the northwest side of the line past the wye on the north side of the line at Van Buren Junction (MP 344.3) with the ex-MP line on the north bank of the river west to Van Buren and Fort Smith, and the beginning of the yards on the north side of the line at Locust Street (MP 343.9), where there are crossovers and a wye on the south side with a remnant of a line that once crossed the river at Junction Bridge. The speed limit rises to 40 mph at MP 343.8.
There is a large yard on the north side of the line in North Little Rock (MP 343.6), with an engine terminal at its west end, a modern connection east-southeast to the erstwhile Cotton Belt line heads away about a third of the way along the yard, crossovers at Crest (MP 341.9), where the RIP shop is in the yard on the north side, the hump yard on the north side, a spur into the Koppers Company Tie Plant on the southeast side as the line turns northeast, the entry-exit track trails in from the yard on the west side at One Lead (MP 340.5), and the end of the yard is reached at the crossovers at North End Yard (MP 339.3).
