Light Rail in Alicante, Spain: Improving the Use of Existing Railway Lines

TRAM Metropolitano de Alicante, a unique, metric (1,000 mm) gage system, was the first Spanish tram–train. Later, it lost its tram–train characteristic (i.e., railway tracks shared with conventional trains) as a result of the evolution of the railway network. Nevertheless, the system still operates in a quasi-tram–train way, because the tram–train vehicle runs partly on railway tracks with a railway signaling system and other railway equipment. This quasi-tram–train operation leads to some specific design issues that are explained in this paper. The paper also presents a thorough description of the Alicante network, its development, its construction and operational costs, its operation, and its demand.
