Portlaoise railway station is one of the busiest railway stations outside of Dublin, and is served by intercity trains between Dublin and Cork and by Dublin commuter services. Maryborough railway station opened on 26 June 1847. It is the terminus of the Portlaoise Commuter Service, which stops at all stations to Heuston and runs hourly off peak and every 20/30 minutes during peak times. It is the busiest county town railway station in the Midland Region, with up to 32 trains to Dublin (10 non-stop) and 30 trains from Dublin (9 non-stop) per day. Córas Iompair Éireann opened a rail depot south-west of Portlaoise town centre in March 2008, with a maintenance and servicing facility for the 183 new intercity railcars and some facilities for outer suburban railcars serving the Kildare route.
