City Centre Resignalling Project

The City Centre Resignalling Project is provided for under the capital investment programme for transport, funded by the National Transport Authority.  The project will meet future demand for rail transport by increasing the capacity and frequency of trains through Dublin City Centre.

The project will provide Iarnród Éireann with the ability to operate 20 trains in both directions through the Howth Junction to Grand Canal Dock line, which caters for Howth DARTs, Malahide DARTs, Northern Commuter trains, Belfast Enterprise services, Sligo Intercity and Maynooth commuter services, as well as other services in the Connolly to Grand Canal Dock area. Signalling on train lines regulate the safe movement of trains, and currently the system’s capacity stands at 12 trains per hour each way.

The Project has also taken in to consideration the need to modernise signalling equipment. Computer based interlocking will be used to replace the existing Relay based signalling systems in Howth/Howth Junction/Killester /Connolly and Pearse.

The project is to be executed in 3 phases:

  • First phase of the project covers the section between Malahide/Howth and Killester
  • Second phase of the project covers the busy Connolly station area
  • Third phase will cover the section between Connolly and Sandymount.


The new signalling system will bring major benefits to our customers:

  • Increased number of trains during peak hours
  • Improved performance of Level Crossings giving longer road opening times
  • Improved punctuality due to the modernisation of signalling
  • Uninterruptible power supplies to ensure higher reliability
  • The new signalling system will facilitate the track layout modifications for the DART
  • Underground and Maynooth and Northern Line electrification projects


The resignalling project will run between Malahide/Howth station and Sandymount. (Length of 21.6 Kms) The project will cost in the region of Є120 million The project work will be completed with minimum disruption to services and to residents living adjacent to the line.
