The train was traveling on a junction shared between the Circumvesuviana service and a Naples
subway route from San Giorgio a Cremano to Naples. The rolling stock involved was an
ETR 200 Metrostar, one of the latest acquisitions from the Circumvesuviana administration, just one year old and with a perfect maintenance record. At 11:10, after leaving the Centro Direzionale station, the train left the rails and hit a wall at the rail-side. The three permanently joined passenger-cars overturned, and the engine hit an electricity pole. The first car was crushed under the second one. First aid was provided by workers from a nearby factory to a man with crushed legs: they used their
belts to stop blood loss, but the man died shortly after being transported to the nearest hospital. Medics of Loreto Mare hospital were on strike (due to salary conditions), but suspended the protest to provide first aid to the injured passengers. While people promptly called the 118 medical emergency number, response from ambulances was slow, taking more than twenty minutes to bring the fifteen
ambulances required to transport the injured from the disaster scene. Twenty technician and three cranes from
Protezione Civile later joined the rescue operations. ==Causes==
