🏴 Uckfield is a town in the Wealden District of East Sussex in South East England. The town is on the River Uck, one of the tributaries of the River Ouse, on the southern edge of the Weald. Uckfield is connected to London Bridge station by Southern services on its Oxted Line via East Croydon. Until 1969 the rail link continued to Lewes; after it was closed Uckfield became the terminus; the station building was rebuilt in 1991 to allow the removal of a level crossing. The Wealden Line Campaign hopes to reopen the closed section to Lewes.
