The safety of the railway line from Enfield to Dublin is an operational matter for Iarnród Éireann and I have, therefore, no function in the matter.
However, I understand from Iarnród Éireann that all safety requirements are being met on the railway line between Enfield and Dublin. Iarnród Éireann has advised me that with the recent doubling of the railway line to Maynooth, the standard of infrastructure on this line has improved. The single track railway line between Enfield and Maynooth has also been recently upgraded. I understand that Iarnród Éireann have plans to further upgrade the railway infrastructure west of Maynooth.
