I don't normally consider a Sunday engineering works closure important enough to be news here, but the fact that the closure of the Huyton - Wigan route on 18th January has only been loaded into the timetable database today suggests last minute panic. Trains between Liverpool and Wigan and beyond are diverted to run via Newton-le-Willows.
As I write, the affected trains are showing as buses on the National Rail site as well, but the Future Engineering Work page does not list this change yet.
I suppose it's good news that things are moving on, but twelve days is not really enough notice. Anyone using a copy of Merseytravel's paper timetable is in for a disappointment.
Update 07 January: This morning's download applied similar changes to the following two Sundays, that is 25 Jan and 1 Feb.
Update 08 January: I'm told a fourth Sunday, 8 February, is also affected, but this information has not reached my database yet.
Update 22 January: Somewhat belatedly, bustitution on Sunday 8 February was added to the database today.
