UKTV has commissioned a second series of Secrets of the London Underground and is set to air on the Yesterday Channel in 2022.

The new 10 episode-long series is set to explore places that will stun viewers that will piece together the rich history of The Tube.

Siddy Holloway from the London Transport Museum will be reunited with rail historian Tim Dunn to explore unseen areas of the London Underground network.

Series one saw the pair take viewers down secret bunkers, abandoned tunnels and other places concealed from the public.

659,000 viewers tuned into the first episode, the biggest launch of a new series for Yesterday.

The series will air on Yesterday in 2022 and will also be available to catch-up on UKTV Play.

London Transport Museum’s director Sam Mullins OBE said, ‘The first series of Secrets of the London Underground proved a huge hit for the Museum and we can’t wait to see Siddy and Tim back for a second series. They’ll be taking viewers behind the scenes to discover even more hidden sites and little-known stories from the rich history of the Tube and how it’s shaped the Capital.’

UKTV’s Hilary Rosen said, ‘After the huge success of series one, series two allows Brown Bob to uncover yet more fascinating secrets from the Tube network. Tim and Siddy make the perfect guides and their combined passion and knowledge for all things London Underground is unrivalled.’

Jacqueline Hewer, CEO of Brown Bob Productions said, ‘We’re thrilled to be producing a second Secrets of the London Underground series for Yesterday, taking cameras to unseen parts of the world’s oldest Tube network, from iconic Leslie Green red-tiled stations to hidden wartime bunkers.

Yesterday’s Gerald Casey added, ‘The show was a smash hit with Yesterday audiences, so I’m delighted that we can satisfy their curiosity even further as we once again unlock the doors into the London Underground’s hidden past.’
