Bus Éireann will be operating shuttle services across the three days.
A mixed week of weather is in store for those attending the National Ploughing Championships.
Day one is set to be dry, with some sunny spells and relatively light winds on Tuesday.
Wednesday and Thursday will see low pressure, bringing in heavy rain, with a mix of sunny spells.
The Ploughing is expected to attract between 250,000 and 270,000 attendees.
Europe's largest outdoor agri-event will boast all the usual mainstays - from the brown bread baking competition, to fashion, high-end machinery and the all important ploughing matches.
Cathal Nolan from Ireland's Weather Channel says attendees should anticipate good and bad weather over the three days:
Irish Rail will be operating shuttle buses from midlands train stations for the National Ploughing Championships.
Bus Éireann will be offering a shuttle service outside Portarlington and Tullamore railway stations towards Screggan across the three days.
