The capital plan to 2016 prioritises protecting existing assets and maintaining safety standards. As a result the bulk of the funding for rail under the plan goes towards asset renewal and maintenance across the rail network. There is limited funding for enhancements and upgrades but some funding has been allocated for projects such as the Dublin City Centre Resignalling (which improves capacity and throughput at Connolly station), removal of level crossings and for new ticketing and customer information systems.
My Department is also pursuing opportunities for funding rail infrastructure under EU programmes such as INTERREG, which even if limited, would be additional to existing resources.
I understand from Irish Rail that there are currently no plans to fully separate the operation of the DART and Enterprise services on the Northern line.
