The Swansea District line (Welsh: Llinell Bwrdeistref Abertawe) is a section of railway line running through the northern part of Swansea, Wales and is primarily used for freight transportation, although minimal passenger services also traverse the route. It was built by the Great Western Railway in 1912 to provide a faster and less steeply graded route between London and Fishguard, in connection with the recently opened harbour at the latter place. It can thereby claim to be the last mainline railway to have been built in Wales. The double track line runs from Cwrt Sart junction at Briton Ferry on the South Wales Main Line to Morlais junction near Pontarddulais on the Heart of Wales line.
