Cinque Terre Express
The Cinque Terre is a region of five villages perched on rocky outcrops on the Ligurian Sea on the northwest Italian coast. Each picturesque village is crowded with tourists. They are all connected by rail via a double-track electrified line via a prodigious feat of tunneling. Only occasionally does the line emerge into the sunlight over the entire stretch. Here in the village of Vernazza, most of the station lies in a tunnel but the northbound line (trains fun left-hand in Italy) emerges above the harbor for a few car-lengths.
Despite the name, the Cinque Terre Express is the all-stops local that runs every 20 minutes or so in each direction, linking all the villages to the outside world. The trains operate push-pull - this one is locomotive leading. Also interwoven into the mix are through expresses and the a few goods trains.
Well worth a visit!
