Adjacent to bridge 3 is Gerry's Hole which is explained by the sign above.
Not a great picture but taken from the top of the remaining abutment shows the Gerry's Hole sign with one of the cap stones on the ground behind it.
Looking north towards Snailswell Lane from Arlesey Road, this is the line of the former embankment. The grass is quite noticeably different to the rest of the field. I am pretty sure the fence on the right is original railway fencing.
Next Ickleford to Henlow Camp.
