Work is to begin this week on a new automatic signalling system on the Tralee to Mallow line. It`s expected the work will improve safety on the line. As a result the train services between Tralee and Killarney will be closed from Thursday to the 25th of February. Bus connections will be in operation as a result. All trains will operate out of Killarney while the work is ongoing. Spokesman for iarnrod eireann Andrew roche says they expect the project to be done on schedule.
