Purchased from CSX, the line interconnects with the Western & Atlantic subdivision of CSX at Elizabeth Yard in Marietta at milepost 22.0 (), located from downtown Atlanta. GNRR tracks include a long rail siding along the east side of the triple CSX tracks, from just north of Kennesaw Avenue, over Tower Road, to just north of Loudermilk Drive, where it rejoins what becomes the main northbound CSX track. The main GNRR track splits from the GNRR siding at a rail switch just north of Tower Road, and parallels the other tracks to just before Marr Avenue, before a sharp turn to the east. Between Marr, Loudermilk, the GNRR siding, and GNRR mainline, there are two dead-end sidings extending north on the east side of the GNRR office, and one of those has another dead-end siding extending north on the west side of the office.
