|} The Limerick to Nenagh line operates over a short section of the line between Limerick and Limerick Junction before joining the Limerick-Ballybrophy railway line at Killonan Junction.
The service is operated by 2700 class diesel railcars, whose top speeds are sufficient for the 60 mph limits between Limerick and Killonan Junction but is hampered by the condition of the track between Killonan Junction and Nenagh.
