Trains that terminate at Kildare are given some extra time compared to those that continue past Kildare. The reason is that some trains terminate at platform 2, the up platform, and are generally held on approach to Kildare by the signalling system as they have to cross over. Sometimes they may have to wait if an up train is running late.
Example - the 2210 to Portlaoise is rostered at 42 mins and only 6 mins from Newbridge while the terminating trains have 45-50 mins.

My understanding is that the ICRs are capable of/designed for 110mph operation. My point remains - brand new high performance trains, lazy undemanding schedules. As for crossing the line at Kildare, this adds perhaps 1 to 1½ minutes to start to stop timings. On my trip start Newbridge to stop Kildare including a signal check to 21.9 mph took 6'-35".
