Access to the structure is difficult. The land to the west of the railway is privately owned and the permission of the landowner or tenant is required before entering the land. One must then cross the railway by one of the few over bridges. On the eastern side the land is open access which is difficult to walk through, there being no gates or gaps in walls to help make progress easy. The ground is very wet for most of the year.
This image is of one of two posts which were located at the the northern and southern ends of the toughs. Lamps which were on top of the posts were lit at night to show engine crews the start and end of the troughs. The crews then knew when to lower and raise the scoop to collect the water.
