In Autumn 2006 a more regular service was provided at Longcross station, with many trains making unscheduled stop due to filming at the QinetiQ site for a new BBC drama, HolbyBlue, a spin-off of Holby City. Three further dramas also used Longcross for filming in 2006: a political drama made by World Productions; Jekyll by Hartswood Films; and the second series of Hyperdrive, a BBC comedy series. Another drama Echo Falls was partly shot at Longcross. This makes use of the mixed pineferous, gorse and heather landscape of wet and semi-wet upland heath, a rare soil type.
The BBC Ghost Story for Christmas "View from a Hill" (by M.R. James) used the station as a location for the opening and closing scenes.
