1955 September, H. A. Vallance, “The Border Counties Line”, in Railway Magazine, page 594:
The head of the North Tyne is reached at Deadwater, 36 miles from Hexham. The river has its source just on the English side of the Border, at the foot of Peel Fell, the most westerly spur of the Cheviots. At first it is a sluggish stream (hence the name Deadwater) but begins to flow more swiftly before it reaches Kielder.
