The first direct Elizabeth line trains between Canary Wharf, the Square Mile and Heathrow airport have started running.
This will mean journeys between the capital’s two key business districts and London’s main airport will take just 40 to 50 minutes – and bring the West End within 30 minutes of Heathrow.
It comes just a week after the opening of Bond Street Elizabeth line station, which marked the completion of the last new station on the new railway.
Services from Reading and Heathrow in the west will no longer terminate at Paddington but will run through the new tunnels under central London to Liverpool Street, and vice versa from Sunday
