On the Maynooth line, the Lexlip Confey station is closed until August 3rd. Passengers should use the Lexlip Louisa Bridge station instead.
A special train will run from Galway and one from Ennis for the All-Ireland hurling quarterfinal replay on Monday. Iarnrod Eireann says advance purchase of train tickets is essential.

The National Safety Council is urging motorists to maintain the improvement in road death figures achieved so far this year, by not drinking and driving. Last year five people died on the roads during the August bank holiday weekend. It also urges drivers to slow down. "It's not worth it."
