Iarnród Éireann has confirmed it is looking to lower their operating costs on a mid-west rail line.

The Nenagh to Limerick line, which was opened in the 19th century, was expanded 18 months ago to offer a commuter service to Limerick.

It was hoped at the time that over 360 passengers a day would use the service. However, Iarnród Éireann said today that the number of journeys per day is averaging at 80.

The company has said it is considering what are known as 'rail-bus technologies', specifically lighter rail vehicles that run on tracks.

The news comes as the company prepares to launch a new service from Limerick to Galway next week.
