I wonder which ones will be withdrawn first?

Try 23 MAN ALX300s  Also, only 27157-65 will be entering service straight away - 27166-81 have been confirmed to me by one of the Union Representatives as being the branded examples (4 in each style as per Richard Smiles' prediction) and that they are to be launched on the 7th November.
The service changes in December (as best we can work out from what little we know) will see the PVR increase by 2 meaning 2 older MAN ALX300s will likely stay on to cover that increase.
