Elizabeth line has high-speed 4G rolled out across whole rail network

Elizabeth line passengers will now have access to high-speed mobile coverage across the breadth of its rail network after a 4G rollout was completed.

All underground and overground sections of the Elizabeth line now have 4G connectivity which Transport for London (TfL) hopes will put an end to areas that have suffered from patchy data coverage.  

London mayor Sadiq Khan, who heads TfL 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.”

Work, undertaken in partnership with TfL and Boldyn Networks, is ongoing to deliver 4G and 5G coverage across all Tube, Docklands Light Railway (DLR) and Elizabeth line networks.

This includes the London Overground Windrush line between Highbury & Islington and New Cross.

Much of central London now has coverage, and work is underway to expand coverage along the Northern line towards Morden.

Coverage is also expected to be expanded to lines between King’s Cross St Pancras and Moorgate by the end of the year or early 2025. 

TfL said the Bakerloo, Piccadilly and Victoria lines will also see improvements completed in the coming months.

Michael Roberts, CEO of London TravelWatch, said: "It’s great that the Elizabeth line is now fully connected, enabling passengers to stay online as they travel around London.

“This is also a really important step towards making passengers feel safer on transport as not only can they get in touch with someone if they feel unsafe or uncomfortable, they can also go online to immediately report anything they see or experience on the network.”
