Spain - Tram services over obscure routes
The Málaga network is called a Metro rather than a Tram because it is mainly underground. It has two routes, L1 and L2, from its terminus at El Perchel. As at January 2020 the two lines were worked as one through route, with a reversal at El Perchel. Each line starts from a different set of platforms, with one set vertically above the other. Line L1 departs from the high level platforms and returns to the low level ones, and the opposite occurs on line L2. There are separate connections between the two levels. An extension into the city centre is under construction and it is thought these connections will cease being used when that opens.
Fira Valencia branch
The 1km long one stop branch from Vincent Andrés Estrellés only operates during Major Exhibitions at the Centre as part of route 4. During 2018 it apparently operated on 82 days so to confirm if running when in the area search on-line in their Journey Planner - entering Fira Valencia as the starting point. Note for an Exhibition in late January 2019 that timings were posted very late.
