Urban tracks for Light Rail Transit (LRT). Dublin experience

摘要

Luas Cross City (LCC) is Dublin new 5.9 km light rail extension (Luas is the commercial name for Dublin LRT), being built as part of the overall development, since 2001, of a new, modern and efficient LRT network for the Irish Capital. One of the major challenges for what is essentially a city central, partly on-street LRT, has been the design and construction of the embedded track system. This design was influenced by the experiences of previous Dublin LRT projects and by the outcomes of benchmark analyses with other European networks and trial track panels. TII (Transport Infrastructure Ireland), is delivering LCC through a D & B contract, based on very strict Employer Technical Requirements. The resulting innovative track design is described in detail in this paper.
