National Transport Authority and Transport Infrastructure Ireland Luas is Dublin's light rail system and consists of two separate lines, the Red Line and the Green Line. The system comprises 42.5 kilometers of track, three maintenance depots, 67 stops and a fleet of 81 light rail vehicles. Luas carried 48.2 million passenger journeys in 2023. Further expansion of the system is anticipated. A more detailed description of the Luas system is given in Appendix A of the IMPQQ Document. It is anticipated that the Luas Operations and Maintenance Contract will commence operations in Quarter 2 or 3, 2026 for a period of seven years from full operational commencement, with an option to extend by up to a further five to seven years. There will be a mobilisation/transition period from the date of contract signing until the operating commencement date. The scope of the Luas Operations and Maintenance Contract will include operation of public passenger services, rolling stock maintenance, infrastructure maintenance (depots, track, etc.) and management and operation of Luas Park and Ride sites. Maintenance of the automatic fare collection system (AFCS) will also be within the scope of the Operations and Maintenance Contract. It is envisaged that revenue risk will be borne by NTA/TII but that some fare evasion risk will be borne by the Operator. The passenger services to be provided by the Operator will be defined by a service specification. There will be a performance monitoring system in place based on a number of key performance indicators. A more detailed description of the scope of the Luas Operations and Maintenance Contract is given in Appendices B, C, D and E of the IMPQQ Document.
