90018 on the down Postal towing the 325's - went through very slowly on Platform 2 - proceeded about half a mile on the slow line - then reversed back towards the station - dropped 325001 in the siding at the back of Plat 1 - and the rest of the consist set off north on the 'down slow' about 160 minutes late. I guess a fair number of folks in Scotland had a late delivery of mail today!
