Just a couple of days too late for Warley, what were they thinking!
Just appeared on the Hattons website in the past few minutes, the BR Blue Class 56 R2645.
See the Hornby website for more info: http://www.hornby.com/locomotives-89/r2645/
A little over the odds at £80 perhaps (Hattons' price) , but I've just ordered one in excitement. Just past the 2pm cut off for guaranteed next day delivery, but fingers crossed!
