The Well-line addresses London’s increasingly urgent pollution and congestion problems.

The Well-line reimagines London as a city with a network of multi-purpose places and spaces, supplied and connected via a repurposed underground brownfield site, delivering long-term health and environmental improvements to Londoners.

The Well-line will transform the disused underground Post Office Railway, running six miles from Paddington to Whitechapel, into an adaptable high-speed logistics route, reducing traffic congestion and pollution. Innovative technologies will revolutionise London’s logistics systems, reviving hidden infrastructure to transport 20,000 parcels per hour, equivalent to 585 LGVs daily, with a projected 30% reduction in city traffic. Additional uses include medical and data transportation, waste removal, energy generation, and local district heating.

The route passes under key districts, including the West End, Oxford Street, Farringdon, and the City. Extended links to the east and west could connect with national and international canal, rail, sea, and air logistics networks. New underground warehousing and multi-level logistics centres along the tunnels will connect via existing shafts to surface hubs, supporting commercial, retail, and community opportunities. Local consultations will identify and prioritise roles for these hubs, linking revitalised, multi-purpose spaces into a healthy clean-air linear park of green oases across the city's densest parts.
