Irish Rail and Córas Iompair Éireann have brought High Court proceedings against Tipperary County Council in a dispute over a train signalling mast near the old Cahir railway station.
The case centres on whether the mast, located about 130 metres from the old Cahir Rail Station, should be treated as exempted development or whether it affects the setting of a protected structure. The station, described in reports as a Gothic revival railway building dating from the 1850s, is at the heart of the planning disagreement.
Tipperary County Council served an enforcement notice in June 2026 under the Planning and Development Act 2000. That notice requires Irish Rail to cease using and remove the signalling mast by September 2026. Irish Rail is now asking the High Court to quash the council’s decision.
Irish Rail argues that the local authority made errors “in law and in fact” when deciding the mast was not exempted development. It also disputes the council’s view of the “curtilage”; the land or setting attached to a protected structure and says the mast is too far from the station building to fall within that protected area.
The rail operator further says it has installed more than 700 similar masts around Ireland without complaint from other planning authorities. It claims the protected status at the Cahir location now applies only to the station building, rather than other nearby railway structures previously listed in older development plans.
The council’s position is that the mast impacts the character and setting of the historic station. The matter is expected to return before the High Court on July 20th 2026.
