(7 hours ago)PH - BQA wrote 7579 was due to go today but is waiting for work, so 7581 went in its place. Given the damage to 7545 I imagine 7579 may stay north for some time to cover for that.
1404 could be the subsitute either maybe? Not ideal having a Pulsar for a Decker but this is Arriva. Believe that was meant to be moving out with these coming in.
