The 'Dublin and Kingstown Railway' (D&KR), opened in
1834, was
Ireland’s first railway. It linked
Westland Row in Dublin with
Kingstown Harbour’s West Pier in
County Dublin.
Before construction even commenced, a survey of existing road traffic through
Blackrock was performed every day for 6-months in
1831 to determine potential passenger numbers. The average daily traffic was found to be 160 private carriages, 620 private jaunting cars and 820 public cars.

Building of the 6-mile line was delayed by opposition from two different landowners who insisted on large cash compensations and in the case of
Lord Cloncurry the building of a private bridge to a bathing area complete with a Romanesque temple, a short tunnel and a cutting to maintain privacy. Part of the line ran on an embankment built across the strand between Merrion and
Blackrock which later led to the formation of
Booterstown marsh.
The line was extended to Dún Laoghaire station’s current location using the then existing
Dalkey Quarry industrial tramway cutting which ran to the West Pier. However, this took a further three years, again due to opposition from local property owners, this time led by
Thomas Gresham. The station building was converted in
1971 to a restaurant, ''Brasserie Na Mara.''
The D&KR later included the
Dalkey Atmospheric Railway branch.

In 1854 the lines were leased to the
Dublin, Wicklow and Wexford Railway Company who changed the original
standard gauge to the wider
Irish gauge.
