Hidden Heroes and Ingenious Innovations that keep London moving

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.
