The time it takes to travel to and from Sligo from Dublin by rail has been brought before the Dáil.
Currently, it takes over 3 hours in both directions, with trains having to come to a halt three times on the route due to one single track between Sligo and Maynooth.
The Sligo-Dublin, meanwhile was excluded from a new published timetable.
Irish Rail published new timetables in the commuter belt between Dublin and Portlaoise and Dublin and Drogheda.
Deputy Frank Feighan says a number of good work has been done, however attention is needed on the line.
