Railway tunnel (west) is a wall forming part of the former railway infrastructure at Moyle in County Antrim, Northern Ireland. The structure sits upon bedrock composed of a Palaeogene-age mafic igneous intrusion, which would have presented significant engineering challenges during the Victorian railway construction phase. This hard volcanic rock, formed during the Palaeogene period, required skilled quarrying and stonework to cut the tunnel through solid igneous material.
The wall represents the engineering response to tunnelling through the challenging geology of the north Antrim coast. The mafic igneous intrusion that forms the local bedrock is resistant and dense, typical of Palaeogene volcanism in the region. Such geological conditions demanded substantial retaining structures to manage both the excavation and long-term stability of the passage.
The site is protected under Historic Environment Division reference 16605, recognising its importance as part of the local railway heritage. The construction of railways through such difficult terrain represents a significant achievement of nineteenth-century civil engineering, adapting to the unforgiving landscape of the Irish coast.
