06:30 from Portlaoise To Heuston - Constantly Late

[RadarControl]

Does anybody know why the 06:30 from Portlaoise is constantly at least 10 minutes late? It arrives in Kildare anytime after 7am when timetable says it should be 06:52am. Most mornings I get it, the train does not arrive in Heuston until 07:50am which is almost 10mins.

For only the third train of the morning it does not make sense how there can be delays so earlier.
