FS Class ETR 300

The ETR 300, also known as "Settebello-type" for its use on the former Settebello train service, is a type of Italian fast electric multiple unit (EMU) trainset formerly operated by Ferrovie dello Stato (Italian State Railways). The letters ETR stood for elettrotreno rapido (Italian for high-speed electric train). Thanks to its aerodynamically low-drag profile, it boasted a maximum speed of 200 km/h (120 mph), with a power output of 2600 kW. Manufactured for FS by Breda, a total of only three trainsets were built, numbered ETR 301–303.

Following development of the design that had begun in 1947, the first ETR 300-series unit began making test runs in September 1952. The first completed trainset, numbered ETR 301, was delivered to FS on 21 November 1952. After the delivery of the second set, number 302, the ETR 300-series trains entered regular service between Milan and Rome on 30 March 1953, on the new Settebello service. The third and final set, ETR 303, entered service in 1959.
