(Yesterday, 7:24 pm)PH - BQA wrote A dozen removed seems slightly too low given the actual board allocations. It's not really about what's to the 'satisfaction of some', more based on what Arriva themselves have boards allocated as. 

Ashington, on paper, should need 12 for the 1/2/57 - and I believe there is 1x 35 single decker board. 13 overall - they currently have 26. 

Blyth have, I believe, 4 boards allocated as single deckers (the 553 and 3x X9 boards). They currently have 13 saloons. 

Between the depots that's 39 saloons for a PVR of 17. Even if you say there's an approximate spare percentage of 14%, that's only an additional 2-3, taking you to 19-20. So you'd think there should nearer to 19 saloons withdrawn, not 12.
