It is the route taken by the Limerick – Tralee/Fenit railway line, which opened in stages between 1867 and 1887. Most of the route closed between 1975 and 1978 but remains the property of CIÉ ( the National Transport Company). Much of the development as a recreational amenity has been undertaken by the GST Ltd. which is a voluntary group assisted by various Local and State agencies – visit southerntrail.net
Today the Greenway is suitable for off road walking and cycling along 40km of the Co. Limerick section of the route between Rathkeale and Abbeyfeale. In Co.Kerry a short stretch has been developed near the Lartigue Museum in Listowel and work has commenced on the Tralee-Fenit section.
