Irish Rail is expecting full services across all of its routes to be back up and running by the end of the month.
5 of Irish Rails routes resumed full services this morning.
These include lines such as the Northern Commuter, Maynooth/M3 Parkway Commuter, and Galway/Dublin lines.
Rail Users Ireland has welcomed the development but feels it doesn't give enough time to fix any issues before schools return.
However, it's predicting that passenger numbers will be lower than usual as people continue to work from home.
