Secrets of the London Underground was first broadcast in the United Kingdom from 19 July 2021 on Yesterday. The series explores hidden areas of the London Underground such as abandoned tunnels, secret bunkers and hidden staircases, and delves into the archives of the London Transport Museum's Acton Depot.[5][6] The format of the programme generally centres around visiting two abandoned areas of the London Underground, in addition to viewing some of the Museum's collection at Acton, usually with assistant director and 'Hidden London' co-developer Chris Nix.[7]
The first programme opened with 388,300 viewers and a 2.7% share, the highest rated programme on Yesterday and the 5th most watched non-public service broadcast programme that week.[8]
The series is a UKTV original, commissioned for Yesterday and produced by Brown Bob Productions, following on from the success of Dunn's previous UKTV series The Architecture the Railways Built. Jacqueline Hewer, CEO of the programme's production company, stated "We can promise one thing - you'll never travel on the tube again without wondering what's through that door at the end of the platform..." UKTV's Hilary Rosen, deputy director of commissioning, described the series as "Viewers are fascinated by the Tube and this series promises unseen locations, fresh stories and secrets galore from right across the city."[9]
After 659,000 viewers watched the first series, making it Yesterday's highest rated programme ever, the show was recommissioned for a second series of ten episodes, which was broadcast between May and July 2022.[10][11] A third series, of ten episodes, was commissioned for broadcast between July and September 2023.[12]
A fourth series was commissioned in February 2024 for broadcast later in the year.[13]

Siddy gets in the driving seat of a machine that moves ballast into place under sleepers to hold the track in position. At Warren Street, on the Northern and Victoria lines, Siddy explores the station’s constant reinvention.
