 Immediately to the north of the stop, the route becomes single track and turns sharply to the east, joining the trackbed of the existing railway line between Crystal Palace and Beckenham Junction stations.The two tracks (Tramlink and Network Rail) run alongside each other, occupying the site of what was previously a double track railway.Transport for London once had plans to extend the Tramlink system to Crystal Palace, which would have involved a junction to the north of Harrington Road, with the extension joining the existing railway in the opposite direction to the current service.
