Thanks to stagecoach East Scotland and the other forum I'm on, the Dundee Area Forum, the 11 new Scania N230UB/Alexander E300 single deckers for St Andrews are
28651 SP62BHX
28652 SP62BJJ
28653 SP62BJX
28654 SP62BKA
28655 SP62BKF
28656 SP62BOH
28657 SP62BRV
28658 SP62BSO
28659 SP62BTX
28660 SP62BUO
28661 SP62BVZ
They will replace the sole remaining PS bodied B10M-55, and also the MAN's at St. Andrews. The two Plaxton bodied B10M-62s, used mainly on route 23, will remain, but are likely to be replaced when the new coaches for the Fife - Glasgow network arrive.
The scania's are, apparently, due to receive some form of branding, so as they'll be used on routes 42, 96, and the 99 group, it'll have some form of Tay connection. The current MAN's new in 2006 have Taylink 99 on them.
As to where the ousted MAN's go, well, it's anyones guess. I'd have expected some of them to head to Glenrothes, which still has the largest allocation of B10M-55s in stock, but we won't know until sometime next week.
