The Elizabeth line will be closed between Paddington and Abbey Wood tomorrow (Saturday) and Sunday this weekend.
Transport for London (TfL) has warned that the closure may cause disruption to journeys on Saturday, November 25 and Sunday, November 26.
On the Elizabeth line between Paddington and Abbey Wood, there will be no service all weekend while planned maintenance including work to deliver mobile coverage takes place.
While these stations are closed, teams will be working to make sure people can use their phones in the underground part of the train track.
This can only happen when the train power is turned off to keep things safe.
This work will support the entire line having high-speed mobile coverage by the end of spring 2024, with the first stations still on track to have 4G mobile coverage by the end of the year.
There will also be no Elizabeth line or Heathrow Express trains to Heathrow Airport over the weekend due to essential works by Heathrow Airport.
As Liverpool Street and Whitechapel Elizabeth line stations will be closed for the routine maintenance on the same weekend, Elizabeth line services will run between Shenfield and Liverpool Street National Rail station all weekend where customers can change for the Central, Circle, Hammersmith & City and Metropolitan lines as well as London Overground, other rail services and local buses.
Howard Smith, Elizabeth line Director, said: “We appreciate it is a complex weekend of closures with Network Rail, TfL and Heathrow Airport all carrying out works which may cause some disruption to customers.
“These works were planned several months in advance and should help ensure that the Elizabeth line infrastructure operates reliably.
“Network Rail and HS2 are also preparing for their new railway and station at Old Oak Common which will also mean some future closures.
“I apologise for any impact on journeys over the weekend and would advise customers to check before they travel using TfL's travel tools, and plan in advance as trains and rail replacement buses may be busy.”
