There are two AT Hairpins at the ford on Batt House road, near New Ridley, which may be in their original position. They are identical in construction (mitred and welded) to the ones re-used near Allendale.

10 re-purposed AT Hairpins spread along the road from Allendale to Catton in Northumberland. They measure 38″ high and 72″ long. The RSJs are 6″ wide. These are the mitred and welded variety which were found to be weaker than the bent rail type and so fell out of use.
