M3 Parkway is a Park and Ride railway station in County Meath beside Dunboyne and the M3 Motorway (Pace Interchange Junction 5).

In 2005, the Irish Government announced that, as part of its Transport 21 plan, the rail line between Clonsilla and Navan would be reopened for passenger trains in two phases.

The extension will involve approximately 40 kilometers of new track and include stations at Dunshaughlin and Kilmessan, improving connectivity for these areas.

Currently, the project is in the development phase, with a focus on design and route selection, and public consultations are expected in the coming two years.

This extension includes electrification and re-signalling of the existing rail lines, enhancing service frequency and capacity to accommodate growing commuter demand from the station.
