Has anyone seen information about planned service patterns once the final phase of the opening is complete? i.e. Something more detailed than 24tph in the core during the peak, 12tph running west of Paddington, 12tph to Abbey Wood and 16tph east of Liverpool street (including the 4 terminators)?
This London Reconnections article from 2018 went into some depth on the expected service pattern west of Paddington:
The leading source for independent news and analysis about transport in London and beyond. Award-winning coverage of transport infrastructure and politics alongside stories about the history of the Capital's transport networks.

With services terminating at Heathrow, Maidenhead and Reading and the existing services stopping at different intermediate stations depending on the final destination, this part of the line has a more complex timetable than east of Liverpool street (all stops either to Gidea Park or Shenfield) and Abbey Wood (all stops on all services).
The 2018 article suggested stations such as West Ealing and Hanwell would receive a significant uplift in services calling. Given I believe 12tph west of Paddington is still the plan, my assumption is this service pattern is likely to remain the plan. But if anyone knows otherwise I'd be interested to hear about it!
