The timetable for the first week of the autumn works at Liverpool Lime Street arrived in my database this morning. Update: I am adding details of later in the period as and when they are released.
Here's a summary of the effects on "our" lines:
On Saturday 30 September and Sunday 01 October buses run between Lime Street and St Helens Central and between Lime Street and Manchester.
On Monday 02 to Sunday 08 October the buses are to St Helens Central and St Helens Junction.
From Monday 09 until Saturday 14 and Monday 16 to Friday 20 October, a modified service will run with two trains an hour all stations Lime Street to/from Wigan, one of which is extended to Preston; and two trains an hour all stations to/from Manchester Victoria. After about 20:00 buses replace trains between Lime Street and Huyton.
Note that these will be the only trains at Lime Street High Level, services on other routes will run from South Parkway or Hunt's Cross.
On Sunday 15 October one train an hour between Lime Street and Manchester Airport, and one train an hour between Lime Street and Preston.
All this information is outside Network Rail's "Twelve week window" so is still provisional. Updates for the final weekend will presumably follow soon.
