Dublin–Navan railway line

Navan was originally a significant part of the expanding rail network in Ireland. The Dublin and Drogheda Railway first constructed a branch from the Dublin-Belfast main line through Navan to the town of Oldcastle which opened in 1850. In 1862, the Dublin and Meath Railway constructed and operated a branch from Clonsilla to Navan off the MGWR main line to Sligo. This line was extended to Kingscourt in County Cavan in 1865, operated by the Navan and Kingscourt Railway. Both of these lines were eventually purchased by the MGWR, while the Oldcastle line was eventually incorporated into the GNR(I). Navan railway station itself was a small single platform stop on the Oldcastle line.[1] The main station for the town was Navan Junction, which had four platforms serving trains on both routes.[2]

In the 1950s and 1960s, there was a large scale rationalisation of the railway network in Ireland, which saw Córas Iompair Éireann close large sections of line. Passenger services on the Kingscourt line were ended in 1947, while on the Oldcastle line they continued until 1958. The lines from Clonsilla and Oldcastle to Navan were lifted in 1963, with the remainder remaining open for freight use following the withdrawal of passenger services - the Gypsum Industries plant in Kingscourt utilised the line as far as Navan Junction before transferring to the Oldcastle line to transport gypsum to the Platin Cement Works just outside Drogheda, while the Tara Mine also uses the Oldcastle branch to transport lead and zinc. Following industrial action by Iarnród Éireann train drivers in 2001, Gypsum freight services from Kingscourt were transferred to road haulage, which led to the remainder of the line being mothballed. The line has been preserved however, with the then Minister for Public Enterprise, Mary O'Rourke TD, ordering Iarnród Éireann not to 'lift' the railway line, as it may be used in the future.

The growth of the economy in County Meath, added to the increase in the population of Navan,[3] has led to calls over the past few years for a rail service to be reinstated from Dublin.

As part of the Transport 21 plan announced by the Irish Government in 2005, the line to Navan was to be rebuilt in two phases as a branch of the Western Commuter line. The first phase would see a 7.5 km stretch from the junction west of Clonsilla. This would feature three new railway stations at Hansfield, Dunboyne and a park and ride interchange called M3 Parkway. The M3 Parkway station opened in September 2010.[4]

The second phase was originally planned to be completed by 2030 but, as of 2019, was deferred and subject to "review".[5] If completed as planned it would see the line extended from M3 Parkway to Navan itself, with further stations at Dunshaughlin, Kilmessan and two in Navan (provisionally titled Navan Central and Navan North).[6] The former, Navan Central, was proposed to be located near Páirc Tailteann.[7] Plans expected that the latter station, Navan North, would be the northern terminus of a reinstated line.[8][9] Plans for both the Dunshaughlin and Kilmessan stations were deferred due to the reduction in exchequer funding for capital investment programmes.[10]

Since the early 21st century, Docklands has served as the terminus for peak time services on the Western Commuter originating from M3 Parkway.[11] The proposal would have seen this station expanded to become the main terminus for Western Commuter services, including from Navan. However, in 2007, Iarnród Éireann announced plans to restore rail services to the long closed Dublin Broadstone station, which IÉ planned to use as its major terminus for commuter services from Mullingar and Navan.[12]

In March 2008, the transport minister blocked these proposals in favour of utilising Broadstone for the Luas system, instead encouraging IÉ to seek planning permission to keep Docklands as the terminus for the Navan line and services from Maynooth and Kildare.[13] As part of the wider improvements to the commuter network around Dublin, it is proposed to electrify the line as far as M3 Parkway which will form part of the planned DART Line 1.

By 2019, no progress had been made on the proposed Navan extension. That year, the Irish government's regional spatial strategy recommended that the status of the plans be downgraded from "implementation" to "review"; seen as a setback to the opening of the line.[5] However, by the end of 2020 the line was once again included as part of a consultation into updating the Greater Dublin Area Transport Strategy.[14]

In January 2023, the Government of Ireland approved a bill for a €750m development plan for the rest of the line to Navan, with a possible opening by 2036.[15]
