The trackbed at Peel Road close to the site of the Poortown Quarry Tramway; the quarry here was served by a single spur controlled by Annett’s Key, affixed to the St. John’s - Kirk Michael portion of the single line staff, equipment originally used to control the spur off the Peel Line for Knockaloe Camp.  The siding was capable of hold eight four-wheel wagons, from which the quarried material was tipped from above, a 2’ 0” tramway running atop the walling.
