Dalkey railway station opened 1854

In 1854 the present Dalkey station opened when the Dublin & Wicklow Railway opened its Dalkey–Bray/coastal connection alongside its new railway to Bray. The station building is attributed to architect George Wilkinson. In 1855 The former atmospheric route between Dalkey and Kingstown reopened for conventional locomotive operation following reconstruction and conversion to the Irish 5 ft 3 in gauge. This established the through coastal railway arrangement. In 1871 a remarkable elevated signal cabin was constructed spanning the railway as part of the station footbridge. This became Dalkey's first substantial signal cabin arrangement. Eire Trains 1879–81 The railway through the area was progressively doubled: Dalkey–Ballybrack around 1879 and Kingstown Harbour–Dalkey around 1881. This greatly increased the importance of proper block signalling and points control at Dalkey. The 1871 bridge-mounted cabin was replaced. A conventional signal cabin was erected at the south end of the Down platform. Eire Trains 1896–1922 This cabin controlled Dalkey's signals, crossovers and the connections associated with the station's sidings/goods facilities. Dalkey operated as a block post between neighbouring cabins on the coastal route. July 1922 - A temporary signal cabin was erected so railway operation could continue. 4 September 1922 Armed Republicans forced the signalman out of the temporary cabin and burned that structure as well. An empty petrol tin was reportedly left behind. 1922–23The DSER subsequently reconstructed/replaced Dalkey cabin. This produced the cabin familiar from later photographs. Eiretrains describes the 1896 cabin as having been partially rebuilt by the DSER in 1922, which fits the documented Civil War destruction and temporary replacements. 30th March 1964 - Dalkey closed to goods traffic. This reduced the amount of shunting and points work required from the cabin, although the cabin remained an operational block post. In 1979 Approval and construction of the DART electrification scheme meant the old mechanical signalling system was scheduled for replacement by modern colour-light signalling controlled remotely. 1981–82 DART infrastructure construction intensified. The traditional local signal cabins along the coastal route were progressively becoming redundant as the new Central Traffic Control system was installed. In 1983 - Dalkey signal cabin was taken out of use. Control of train movements was transferred to CTC at Connolly. Dalkey, Dún Laoghaire and Killiney were among the local cabins eliminated during this stage of the DART resignalling , the signal cabin was demolished. DART services started in July 1984 and by 2011 platforms were extended to accommodate 8 carriage trains .
