from a press release:
The full peak Elizabeth line timetable will be introduced on Sunday 21 May 2023.
Peak time frequencies will increase from 22 to up to 24 trains per hour between Paddington and Whitechapel, with 16 trains per hour running off-peak. There will be 12 trains per hour running between Canary Wharf and Abbey Wood in the peak, restoring the frequency that was in place between May and November 2022 to a train around every five minutes. The peak will also now last for longer, increasing capacity even further.
Services will also run all day between Shenfield and Heathrow Airport (Terminal 5) for the first time, with two trains per hour providing direct connectivity between Essex, east London and west London.
There is also the addition of more services at peak time between Liverpool Street National Rail station (platforms 15 -17) and Gidea Park, providing a faster route for those exiting to Bishopsgate.
In the west, there will be an increase in peak services from Reading, with some trains that were previously operated by Great Western Railway transferring to become Elizabeth line services with reduced stops.
There will also be the removal of any significant pauses for trains between Paddington and Acton Main Line, as has been the case with some trains waiting between the stations since November 2022 while they waited to join Network Rail tracks or enter Elizabeth line tunnels. These pauses were built into the timetable, but customers on these services should see reduced journey times between Reading and Paddington and improved journey times for customers travelling from the west into central London.
Customers will receive more frequent services to and from Heathrow Airport as part of this timetable. The airport overall will receive six Elizabeth trains per hour all day. All Heathrow trains stop at Terminal 2&3, with four per hour continuing to Terminal 4, and two per hour continuing to Terminal 5.
