Construction began in 1844, when the GS&WR built a line from Kingsbridge Station (now Heuston Station, Dublin) to Cashel in County Tipperary, later extended to Cork. Amalgamations between the GS&WR and other smaller railway companies in the south led to the line gaining connections to other population centres.
