Early railway development in Ireland took place when the entire
island, north and south, was part of the United Kingdom.
The first railway in Ireland was opened in 1834 between Dublin
Westland Row (now Pearse) and Dunleary (Dun Laoghaire). It was built to
the so-called “Stephenson” gauge of 4ft 8½in (1435mm) which was
rapidly becoming accepted as the standard gauge for all new railways
in England, and was soon to be adopted in continental Europe.
Unfortunately for standardization, the second and third railways
to be built adopted quite different gauges. The first section of the
Ulster Railway between Belfast and Lisburn opened in 1839 with a gauge
of no less that 6ft 2in (1880mm), while in 1844 the Dublin and
Drogheda Railway opened with a gauge of 5ft 2in (1575mm).
Clearly this state of affairs was untenable from the point of view
of a viable interlinked railway system, and after much debate and
government legislation, a compromise gauge of 5ft 3in (1600mm)
was adopted for all new main line railways. The existing railways
were eventually converted to this gauge.
Some remote rural areas were served by light railways of 3ft
(914mm) gauge, a few of which survive today as tourist operations.
2ft (610mm) and 3ft (914mm) gauge were used for the extensive networks
of lines constructed to serve the peat extraction industry.
In 1876 a number of existing railways were combined to form the
Great Northern Railway (Ireland) or GNR(I). In 1921 the Irish Free
State was established, creating a new land border with Northern Ireland.
In 1925, all railways whose lines were wholly within the Irish Free
State were combined into the Great Southern Railways. This did not
include the main Belfast to Dublin line of GNR(I), nor several small
local railways some of which crossed and recrossed the border several
times. These continued a somewhat schizophrenic existence for many
years, but all cross-border lines had been closed by 1960, with
the exception of the important Belfast to Dublin line.
Northern Ireland Railways were nationalised in 1948 at the same
time as British Railways, while railways in the Irish Republic were
nationalised in 1950. This left the GNR(I) main line as an anomaly,
still in private hands. Finally, in 1953, this line, too, was taken
into State control, responsibility for it being divided between the
respective railway administrations of Northern Ireland and the
The major cities, like cities in the United Kingdom, lost their
original tram systems many years ago. However, Dublin now has an
extensive modern tram system, the first line of which opened in
2004. The system uses the international standard gauge of 1435mm.
- Bord na
Móna the Irish peat authority. Peat extraction ended in 2020,
