The contract covers substations, remote power control (Scada), signalling, telecommunications, security systems, and a control centre.
The 5.6km line will run north from the existing Green Line terminus at St Stephen's Green, crossing the Red Line at the junction of O'Connel Street Upper and Abbey Street and serving the new Dublin Institute of Technology campus at Grangegorman before terminating at an interchange with Irish Rail's Broombridge station. Preliminary works are already underway and major construction is due to start next year. Commercial services will begin on the 13-station line at the end of 2017
