The Railway of the Temples represents the best way to access the Valley of the Temples and admire a landscape unique in the world, recognized as a UNESCO World Heritage Site since 1997 and protected, since 2000, by the Archaeological and Landscape Park of the Valley of the Temples of Agrigento. The 10.1 km long line connects the Agrigento Bassa station (still active on the Palermo-Agrigento Centrale line) to the Porto Empedocle Succursale station (formerly connected to the narrow-gauge Castelvetrano-Porto Empedocle railway, closed in the section between Porto Empedocle and Ribera in 1978). It represents the terminal section of the active Palermo-Agrigento line, opened between 1863 and 1876, which originally ended in Porto Empedocle. In 1933, the urban section connecting, through the San Gerlando tunnel, the Agrigento Bassa station with the new Agrigento Centrale station, which became the new terminus, was opened. The Agrigento Bassa-Porto Empedocle section remained as a branch line of local interest, useful for continuing on the narrow-gauge line to Castelvetrano (active since 1923). In 2001, an experimental urban passenger service, only on holidays, with a stop at the Temple of Vulcan, was activated. The line definitively reopened on June 8, 2014, by Fondazione FS Italiane for tourist service only.
