greater number of services operated by ICRs.
Thats already happening a Mark 4 set operating to Cork has being replaced by ICR for the last number of weeks.
09.30 to Heuston
13.00 to Cork
16.30 to Heuston
21.00 to Cork (only guessing this services as the 16.30 arrival from Cork tends to operate back to Cork at 21.00)
