I doubt if Cregg Road crossing will be automated: there is probably no budget for that: and anyhow there are loads of other manual crossings on the line. The present time table does not require Carrick as block post, and in fact there are no crossings scheduled of regular passenger trains between the Junction and Waterford. So in signalling terms there is nothing new in the new timetable: turning all manual crossings and block posts into split shift operation would seem to be the name of the game.
Carrick might well remain a block post even if only to facilitate timely communication of train running to mid-section level crossings.
