IDOM has prepared design proposals for the new LUAS cross city, an extension to the Green line tram in Dublin. The design is a double track alignment, 5.6 km long with a width of 1,435 mm. running from the from stop at St. Stephen’s Green in the Centre of the city to Broadstone, opposite the bus depot. From Broadstone until the end of the line, the track will run along the old railway cutting. This new line will have 14 stops, depot building, and offices which will be completely integrated into the different urban environments.
The design proposal includes a geometric definition of the alignment in urban areas and cuttings, keeping the disruption of the Red line, already in operation, to a minimum during construction. Another challenge resolved in the proposal was the design and remodelling under the existing bridges and walls of the old rail embankment dating back some 200 years. The stops are integrated into the urban environments by adapting the configuration of all the furniture elements and the materials used to the characteristic of the location. Power supply for the 750 Vdc line will come from the existing substations and two new substations located near Broadstone and in the Broombridge depot. Idom have also provided a concept design for the new Depot building which will provide an additional repair and maintenance facility for the tram system. This functional building is architecturally integrated into the environment and is inspired by the industrial landscape of the surrounding areas and the form of the tram car. The building has two maintenance tracks, office, and car parking.
