As part of the Exchequer capital investment programme, the first phase of the proposed railway linking Navan to Dublin opened in September 2010. Over 25 trains each way per day now run between the new M3 Parkway Station, Dunboyne and Dublin city centre.
Iarnród Éireann had proposed extending the existing line from M3 Parkway Station to Navan. However, this project has been deferred due to the reduction in the Exchequer capital investment programme.
The proposed extension consists of 34km of railway line with stations located at Dunshaughlin, Kilmessan, Navan town centre and a further station on the northern edge of Navan.
