of Westland Row, Dublin
The Dublin and South Eastern Railway (DSE) was originally incorporated by Act of Parliament in 1846 as the Waterford, Wexford, Wicklow and Dublin Railway Company. In 1860 it was renamed the Dublin, Wicklow and Wexford Railway Company and on 31 December 1906 it was renamed again as the DSE. Amongst the lines forming the DSE was the Dublin and Kingstown Railway, which was authorised in 1831 and opened in 1834 - the first public railway in Ireland. The Kingstown-Dalkey section was operated by atmospheric traction for a short while. The railway formed part of the Royal Mail route between London and Dublin via the packet station at Kingstown (now Dún Laoghaire).
