The entire Elizabeth line now has mobile coverage, including tunnelled sections.

Transport for London (TfL) and Boldyn Networks have completed the work to provide high-speed 4G mobile coverage across the entire line.

This means customers can stay connected throughout their journey, a significant milestone in the Mayor and TfL's commitment to bring mobile connectivity to London's transport network.

The Mayor of London, Sadiq Khan, said: "Bringing mobile coverage to the Underground network is a key commitment of mine, so I’m delighted that the entire Elizabeth line network now has 4G connectivity.

"This is yet another step towards ensuring Londoners and visitors can stay connected on our transport network and means customers can access the latest travel information, keep in touch with colleagues, friends and family throughout their journey on the Elizabeth line."

The first tunnel sections between Paddington and Liverpool Street received mobile coverage earlier this year.

Now, the remaining tunnels have been equipped, allowing seamless connectivity for those travelling across central London to Whitechapel, Stratford, Canary Wharf, Custom House, and Woolwich.

The expansion of high-speed mobile coverage to London's underground stations and tunnels allows customers to remain connected as they travel around the capital.

This is also a key part of TfL and the Mayor's plan to help Londoners stay safe while using the network.

The four mobile network operators – Three UK, EE, Vodafone, and Virgin Media O2 (VMO2) – are all part of the rollout.

The extended coverage will also provide TfL staff with better connectivity to support the safe and reliable running of the network, as well as host the new Emergency Services Network (ESN).

When fully operational, the ESN will provide first responders with immediate access to life-saving data, images, and information in live situations and emergencies.

Andy Lord, London’s Transport Commissioner, said: "I’m delighted that the entire Elizabeth line now has mobile coverage, making it even easier for customers to stay connected especially as we approach the festive period.

"This has been a vital project for our customers involving a range of complex engineering skills, all carried out during engineering hours, and we are working hard to bring the benefits of being able to stay in contact while travelling through our city as quickly as possible to the rest of the network."

Boldyn Networks, awarded a 20-year concession by TfL in June 2021, is working to introduce high-speed 4G and 5G mobile coverage across the whole Tube, Docklands Light Railway (DLR), and Elizabeth line network, including on the London Overground Windrush line between Highbury & Islington and New Cross.

Large sections of central London now have coverage, and work is underway to expand coverage along the Northern line towards Morden, as well as between King’s Cross St Pancras and Moorgate by the end of the year and early 2025.

Coverage on the Bakerloo line will shortly be extended along the tunnelled sections between Piccadilly Circus and Embankment, with further stations along the line, as well as the Piccadilly and Victoria lines, set to get coverage in the coming months.
