As part of the Transport 21 plan announced by the Irish Government in 2005, the line to Navan would 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 park and ride interchange called M3 Parkway. This became operational in September 2010. The second phase was originally planned to be completed by 2030, but as of 2019 is deferred subject to "review". 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). The former, Navan Central, was proposed to be located near Páirc Tailteann. Plans expected that the latter station, Navan North, would be the northern terminus of a reinstated line. Since the early 21st century, Docklands has served as the terminus for peak time services on the Western Commuter originating from M3 Parkway. The proposal would have seen this station expanded to become the main terminus for Western Commuter services, including from Navan, as well as a stop for planned DART services through the DART Underground. However, in 2007, Iarnród Éireann announced plans to restore rail services to the long closed Dublin Broadstone station - it was this that IÉ planned to use as its major terminus for commuter services from and Navan. 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 in place as the terminus for the Navan line, as well as services from and . As part of the wider improvements to the commuter network around Dublin, the line is proposed to be electrified as far as M3 Parkway and will form part of the planned DART Line 1. By 2019, no progress had been made regarding the proposed Navan extension. The Irish government's regional spatial strategy recommended that year that the status of the plans be downgraded from "implementation" to "review"; seen as a setback to the opening of the line. Although the proposal to reinstate a rail service between Dublin and Navan has been welcomed, particularly in view of the comparison of cost with the M3 motorway (estimated to be €650 million against €90 million for the railway), there has been criticism of the details of the proposal by the pressure group Rail Users Ireland (formerly "Platform 11").
