Andy Byford, London's Transport Commissioner, said: "Our thoughts are with His Majesty The King and all members of the Royal Family following the death of Her Majesty The Queen. Thousands of people from all over the UK and beyond are expected to make their way to London to pay their respects. We are working with our partners to keep our city moving smoothly and to ensure that everyone who is planning to attend the memorial events can do so safely.  

"Roads and public transport in central London will be very busy, so we advise everyone to allow plenty of extra time for their journeys and to avoid driving where possible. All Londoners and visitors to the capital over the coming days should check before they travel using the latest real-time travel information, which is available on our TfL Go app and on tfl.gov.uk. Additional TfL Travel Ambassadors will be on hand across our network to answer questions and to provide travel advice to anyone who needs it."
