Carrickmacross is the terminus of a short six mile branch from Enniskeen on the former Great Northern Railway's Irish North West line from Dundalk to Enniskillen. The branch line opened in July 1886. These lines closed to passengers in 1957, but remained open for parcel and goods traffic until 1959. Track lifting commenced at Dundalk and by 1960 the Carrickmacross branch line was no more. The main station building, which consisted of a typical GNR terminus with a train shed similar to Ardee is now demolished, but the engine shed, water tower base and typical GNR station masters house survive.
Although the station at Carrickmacross has been demolished, the station masters house survives. It is a typical Great Northern Railway design, dating from the 1880s. The stone locomotive shed also survives at Carrickmacross Station, now a private residence. A housing estate has been built on the former station site, appropriately named 'Railway Court'.

The stone built base of the water tower is also clearly evident at Carrickmacross. Although the tank is missing the structure has since been converted into another private residence.
