Hidden Heroes and Ingenious Innovations that keep London moving
Mind the Gap: The Official TfL PodcastShow Notes
All aboard the newly refurbished Central line trains! Join Tim Dunn as he catches an exclusive first-ever ride to see the results of the biggest upgrade programme in the Tube’s history. Joining him is special guest Paul Marchant, the man behind the Central line’s new seating fabric and fascinating patterns (know as the moquette). That’s just one small part of an enormous programme of investment and upgrades on the Central line, that has seen years of work and planning go into new engines, new CCTV, and a long list of multiple system upgrades. Tim then takes you behind-the-scenes at the world-leading Railway Engineering Workshop in Acton to meet Aaron, Becky and Robbie - just some of the dedicated and highly skilled staff who work on maintaining, upgrading and repairing Tube trains all year round, on an incredible scale.

On a very sunny rooftop overlooking central London, podcast guest presenter Louis VI meets Lilli Matson, TfL's Chief Safety, Health and Environment Officer to talk about the city she helps to keep moving - and changing.
For London Climate Action Week 2026, guest presenter Louis VI heads to a tube station platform for a personal chat with Mete Coban, London's Deputy Mayor for Environment and Energy — the person tasked with steering one of the world's biggest cities, and its transport network, toward net zero. In this episode, they get into the scale of the challenge: how London and TfL plans to power itself, what rewilding actually looks like, and what the climate targets that are often talked about actually mean for the lives of real Londoners.
TfL's official podcast returns for London Climate Action Week 2026. Musician and zoologist Louis VI takes the reins as guest host, sitting down for insightful and genuinely personal chats with the people actually making the calls on London's climate future — the Deputy Mayor for Environment and Energy, and TfL's Chief Safety, Health and Environment Officer. Expect the big stuff: electric buses, TfL rewilding, cleaner energy for transport, and London's ambitions to lead the world on climate. But also the unexpected — including a beaver called Justin, and a plan to turn the entire city into a giant sponge.
Tim puts on his very best moquette socks and accepts a generous invite into the heart of City Hall, to chat with Deputy Mayor of London for Transport Seb Dance about a couple of big questions, including:
What's the biggest innovation of the last 25 years on public transport in London? Is it the Elizabeth line, the contactless revolution, the Overground line naming, electric buses, new trains that are incoming on the Piccadilly line and DLR - or something else? What about the Night Tube?
