It's after a vehicle hit the railway bridge.
The Heuston to Portlaoise train service, which was delayed after a vehicle hit a railway bridge, has resumed.
Irish Rail suspended the service between Newbridge and Kildare until an inspection of the bridge was carried out.
It is now operating with a 30 minute delay.
