The line has four high steel trestle river valley crossings, built between 18 to replace earlier structures. From University City to Fernwood–Yeadon, the line is grade-separated immediately west of Fernwood/Yeadon station, the abandoned Newtown Square Branch diverges north. The West Chester branch turns west, curves around the Woodlands Cemetery, and heads west towards Elwyn. At Arsenal Interlocking, just south of Penn Medicine, there is a junction with Amtrak's Northeast Corridor where Airport and Wilmington/Newark trains diverge. Media/Wawa Line trains use the West Chester Branch, a former Pennsylvania Railroad line, which diverges from the SEPTA Main Line at 30th Street Station. Elwyn, terminus of the line from 1986 to 2022
