17 new trains were ordered for the service, labelled "Arrow" at the time.
Its 30 years to the day since Irish Rail launched the Heuston to Kildare commuter service.
17 new trains were ordered for the service, labelled "Arrow" at the time.
They were the first diesel trains in Ireland to operate without a locomotive pulling or pushing carriages.
New stations were also built at Cherry Orchard, Clondalkin, Hazelhatch and Sallins.
Irish Rail has now repainted one of the original trains in their old colour scheme to commemorate the anniversary of the service.
