The Elizabeth line is expected to open on Tuesday 24 May if testing and approvals progress as expected. Four railway stations will join the national railway network because Bond Street is not expected to be ready in time. Services will initially operate six days per week between Paddington and Abbey Wood. 12 trains per hour will operate in each direction between 0630 and 2300.
Services are expected to improve in the autumn when Heathrow, Reading and Shenfield services start operating through the central tunnels.
A special service is expected to operate on Sunday 5 June as part of the Platinum Jubilee weekend.
