A linear earthwork, representing a disused colliery tramroad, runs for some 635m west-south-west from a junction with the Saundersfoot Railway (nprn 43052) to SN 10880 07066 at the western edge of a large area of coal workings (nprn 400200). The line of the tramroad and the coal workings are shown on the first edition Ordnance Survey 25in mapping of 1889.
From the junction with the Saundersfoot Railway, a further, similar linear earthwork is visible on aerial photographs, diverging from the railway to the east for about 200m to SN 1175 0710, bifucurating as it does so, possibly representing railway sidings.
