I think you're getting a bit confused. Celia says it like that, not Anne. So you'll hear it more, not less.
I've read greater west's post wrong, I read it as Anne was replacing Celia.
I do have to say that thankfully Dysopian Anne is disapearing from Northern but I can't help thinking that on some stations Northern should re-roll out late Phil Sayer to provide alternate platform annoucements in the former Southern style -
now that would be a rarity!
Obviously this can only work on some lines as there isn't a recording of him annoucing Ilkeston, Low Moor, Kirkstall Forge or Apperley Bridge - however a cut and shut of other annoucements could be achieved from exisiting recordings and using soundalikes. Either that or get GWR Rodger in the system too, it'd be very interesting hearing him pronoucing Slaithwaite, Frizinghall, Brighouse, Brockholes and Ulleskelf.
One other rarity (for me at least) is hearing GWR Rodger warbling away at Temple Meads, as its mostly Dysopian Anne.
