The South London Line passes across the south end of Loughborough Junction station via a bridge but has never had platforms there. This line is now part of the London Overground network and, in December 2012, an extension connected the South London Line to the East and West London Lines, allowing rail services to run across South London from Surrey Quays to Clapham Junction. However, Loughborough Junction is not an interchange station, and no London Overground platforms are planned there as the line is on high railway arches, making the cost of any station construction prohibitive.
