Mind the Gap: The Official TfL Podcast

Tim Dunn starts his journey across the London Overground map to uncover the incredible stories behind the six new line names.
In this first episode, Tim travels to a hospital that Princess Diana visited 17 time: the Mildmay, a small but crucial charitable NHS hospital with a long history of helping Londoners in need, from the cholera outbreak in 1866 to supporting and treating patients affected by HIV and AIDS.
The Mildmay line journey
Tim meet former patient, campaigner and AIDS survivor Jason Reid, who tells his story of becoming seriously ill with AIDS in the early 2000s and the importance of Mildmay hospital staff supporting him and helping him to survive during an incredibly difficult time mentally and physically.
Tim is also taken on a tour of the facilities by Mildmay CEO Geoff Coleman, and speaks with social worker and safeguarding lead Beverley Nelson, who's been working at the Mildmay for 14 years and talks about the community lead approach and environment created at the hospital.
We’ll be travelling right across the map on the London Overground to speak to people who’s stories are interwoven with the names of the new names of London's Overground lines, and we'll be delving into some amazing stories about survival, equality, breaking barriers, and the history that’s made London what it is today.
