Further to my previous report of bustitutions on the Huyton-Wigan line, this morning's database updates show withdrawal of Liverpool-Manchester via Chat Moss services this coming Sunday, giving only two day's notice!
Liverpool - Preston services, which were to run via Newton-le-Willows, are also replaced by buses.
Update: The notice of this change on the National Rail site (Which appeared about 17:00 today.) says it applies for six weeks.
Further update: A press release from Network rail here confirms the six week period (Until Sunday 1 March) and also adds that the bustitution of late evening trains will be expanded to include Fridays, until 27 February.
