After an number of years of bustitution, I'm pleased to report that the Liverpool end of the line once again gets a seven days a week late service, starting on Monday 8 September.
Complete details have not yet been loaded on the timetable database, and at this distance everything must be regarded as provisional.
While I'm on the subject of the timetable database, I note that at the time of writing neither my database nor the National Rail journey planner have details of the last two days of the Huyton blockade in July (Saturday 12 and Sunday 13 July.). I'm assuming this is just an admin. issue but it is possible that trains will run on those days after all.
Update: The trains on those two days have now been removed, and the buses added.
