The MGWR envisaged extending the line from Kingscourt to Cookstown via Carrickmacross, Castleblayney, Armagh and Dungannon, but this never materialised.

[1] (A line from Castleblayney to Armagh, via Keady, was eventually built in the early 1900s and operated by the Great Northern Railway (Ireland).)

Goods services from Kingscourt to Dublin Port via Navan and Clonsilla were re-routed via Drogheda in 1958[1] and then largely withdrawn in 1963, following which the section to Navan was used almost exclusively for the transport of gypsum from a terminal adjacent to the station, owned and operated by BPB Gypsum Industries.

After a strike by Irish Rail staff in 2001, Gypsum Industries decided to transfer its traffic to road.

The line was eventually lifted to create the Boyne Valley to Lakelands Greenway, which was completed in 2024.
