I was in Hexham today, and returned on the Ten (as it was the first one to arrive) which is not serving central Corbridge due to gas main replacement works (road closed for up to two weeks).
As the 685 was scheduled 5 minutes behind the Ten (which was itself about 5 minutes behind schedule) I waited to catch the 685 to take me across the river.
The Stagecoach service arrived 20 minutes behind schedule and the driver explained that this was due to leaving Carlisle late having had to find a replacement vehicle (problems with the 'lift' - I presume he meant the kneeling).
