A hollow-way is exactly what the name suggests: a path so persistently used over generations that feet, hooves, and wheels gradually wore the ground down below the level of the surrounding fields, leaving a sunken corridor between low banks. This particular example runs for approximately 500 metres in an east-west direction, and while much of it has been absorbed into modern agriculture, the eastern portion survives with enough physical detail to reward a careful look.

The hollow-way extends westward from the northern edge of a former settlement, running downslope across the Kilbragh townland boundary into Railstown. The 1906 edition of the six-inch Ordnance Survey map still showed its western stretch of roughly 300 metres as a corridor defined by roughly parallel field boundaries, around 12 to 15 metres wide, but the southern boundary has since been levelled and that section now leaves no visible trace above ground. The eastern 200 metres are better preserved, delineated by a low bank and scarp on either side. The banks are modest in height, under a metre, but they are consistent enough to be measured: the southern bank stands around 0.4 metres on its inner face, the northern scarp reaches about 0.66 metres. One detail is particularly telling. About 100 metres from the eastern end, the hollow-way deliberately widens out to 13.5 metres for a stretch of roughly 20 metres before narrowing again. That kind of intentional broadening suggests a passing place or a gathering point, perhaps somewhere animals could be turned or held, which points to a route used for livestock as much as for foot traffic. Railstown church and its graveyard lie about 400 metres to the north-north-west, and the proximity is unlikely to be coincidental; hollow-ways in Ireland frequently served as processional or functional links between settlements and places of worship or burial.
