UKTV has confirmed that it has commissioned a third series of Secrets of the London Underground, which is set to be aired on the Yesterday channel.

The series has always been popular with viewers, with the first series (aired in 2021) becoming Yesterday’s biggest ever launch of a new programme, and the second series was Yesterday’s second biggest launch in 2022.

Siddy Holloway, Engagement Manager at the London Transport Museum, joins Tim Dunn once again for the third series, which is set to be aired later in 2023.

Filming and production is already underway, and joins The Architecture: The Railways Built and Hornby: A Model World as original shows returning for new series in 2023.

UKTV’s Helen Nightingale said, “I love Secrets of the London Underground! The way the programme brings the history of the Tube to life in such a unique manner is really wonderful. I’m so pleased that Siddy, Tim and the brilliant team at Brown Bob have found even more secrets to share with us.”

Jacqueline Hewer, CEO of Brown Bob said, “There is such a fascination with the London Underground, and we’re delighted to be able to take Yesterday viewers behind the scenes of the tube once again. We’ve got more hidden places to unlock and more intriguing secrets to reveal – with Tim and Siddy bringing stations to life in their brilliantly enthusiastic way.”

Gerald Casey added, “I’m so pleased we can bring Secrets of the London Underground back for a third series. The programme has captured the imagination of Yesterday viewers, and it’s easy to see why with such brilliant access, expert insight and warm enthusiasm. We can’t wait for series three to air later this year.”

London Transport Museum’s director Sam Mullins OBE said, “As the Underground celebrates its 160th year in 2023, it’s brilliant for us to be bringing more of its secrets to Yesterday’s viewers in a third series. I thought I knew the Tube pretty well but can’t wait myself to see Siddy and Tim unlock the door on more unexplored locations and delve into the Museum’s archives to reveal more stories from the London’s unique history.”
