UKTV has commissioned a second series of Secrets of the London Underground (10x60') from Brown Bob Productions, for its leading factual channel Yesterday, set to air in 2022.

The series promises to go further afield, exploring places whose very existence will stun viewers, but allow them to piece together more of the tube's rich and intricate history.

It will also reunite rail historian Tim Dunn (The Architecture The Railways Built) with Siddy Holloway from London Transport Museum. With Siddy's privileged access to the Tube, series one saw the pair take viewers down to abandoned tunnels, secret bunkers and hidden staircases that have been concealed from public view for years.

The first series of Secrets of the London Underground launched to a record-breaking 659k, with the opening episode becoming Yesterday's biggest ever launch of a new series, the channel's highest rated programme ever and the 2nd highest rating non-terrestrial programme of the day.

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."

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