After Utilities have been diverted the new Luas tracks can be constructed. The supporting structure for the tracks is built, new track laid and the surrounding roadway and footpaths reinstated.
Electrical power, signal controls and other systems are needed to operate Luas trams. The overhead cables will be erected and the myriad of electrical and mechanical systems put in place to ensure safe operation of the system.
As works are completed the extensive testing phase will begin. The focus will be on ensuring every aspect of the system is working to the highest safety standards prior to the service being put into operation. During this phase trams will start running on the extension but will not carry passengers as the system is under test. It is anticipated passengers will begin travelling on the new line during the latter half of 2017.
