The line diverges from the line between and the Barrhead at Muirhouse North Junction station is immediately after the junction, and the line turns east passing under the line from Larkfield Junction. Running between retaining walls the line reaches Queens Park station and then Crosshill, turning sharply south still below natural ground level to Mount Florida. Now on an elevated section the line runs to Cathcart North Junction, where the grade-separated divergence to Kings Park leaves. The line now curves sharply west to Cathcart station and Cathcart West Junction where the alternate route from Kings Park converges, and the Neilston line diverges. The line turns north west still on an elevated section and runs through Langside and Pollokshaws East. There is a short climb of 1 in 68 followed by a sharp descent to Shawlands, after which the line crosses the Glasgow to Barrhead line and curves north and then east to Maxwell Park station. The line then enters a cutting to meet Pollokshields West station, rejoining the Barrhead line at Muirhouse Central Junction.
