Could they not have just covered the obsoleted logo with stickers printed with the new logo?That would be logical, but this whole re-branding exercise has been anything but.
The place where I work has such stickers for its bags of kindling to change its net weight label from 5kg to 7kg. (Granted, I would've done a better job of designing those stickers than printing a yellow "7" on a small red square within a large white sticker, but that's none of here, there or yonder.)
Seems to defeat the purpose of removing the timetables for the logo, when train crew are still displaying the Cityrail logo, can still see the Cityrail network map in trains, etc.
Not holding my breath on new timetable posters becoming available until the new timetables come out in October.
