Under the chalk cliffs east of Folkestone sits the Warren, a coastal wilderness largely owned by the railway, hosting a nature trail for walkers, as well as the Victorian rail line that runs on to Dover.

It is also, problematically for Network Rail, an active landslide. “Our monitoring here,” says Derek Butcher, principal geotechnical engineer for the southern region, “shows we’re actually moving ever closer to France – despite Brexit.”
