'Ghost' train station discovered by Thameslink workers

A train station last used by London's commuters a hundred years ago has been rediscovered by engineers.

Southwark Park in Bermondsey was used for over a decade, before trams and buses became more popular.

Parts of the station were then forgotten about and considered "lost", until engineers working on the multi-billion pound Thameslink upgrade uncovered it. BBC London's Asad Ahmad reports.
