The ETR 460 is a development of the ETR 450, a Pendolino EMU developed in the 1970s, being characterized by improved layout, electrical and electronic systems, and improved comfort. Maximum speed remains unchanged at 250km/h (155mph). The ETR 460 spawned two similar types of Pendolinos: the ETR 470 and the ETR 480. The main difference between the versions is that the 460 runs only on 3 kV DC, the 470 on 3 kV DC and 15 kV AC, and the 480 on 3 kV DC and 25 kV AC (used on new high-speed railways in Italy). Three sets were modified to be capable of additionally running on 1.5 kV DC for use on Milan-Turin-Lyon services, but have been all re-converted to the ETR 460 standard and renamed ETR 463. The British Class 390, the Slovenian series 310, the Portuguese Alfa Pendular, the Finnish Sm3 and the Spanish Alaris series were all derived from the ETR 460.
The trainset has the ability to tilt by up to 8° when taking corners so as to reduce the effect of centrifugal force on the passengers. The passengers remain comfortable even if the train fully takes advantage of the characteristics of the track thanks to the lightness of the construction (only 13.5t or 13.3 long tons or 14.9 short tons / axle). Use of the train does not demand particular modifications to the railroad but it is expensive in terms of maintenance of the rolling stock due to the complexity of the tilting system.
The hydraulic tilting system it is governed by two gyroscopes located in the lead cars. The curve is found on the base of the elevation of the external track.
ETR 460s are provided with 12 three-phase asynchronous motors (compared to the 16 in the ETR 450) located in all cars, in order to improve cornering capability. The motors are controlled by GTO-VVVFinverters, with a total power of some 6 MW. Electric braking is of rheostatic type, with the possibility of energy recovery at some speeds while the mechanical braking system uses disc brakes, commanded by an electro-pneumatic system called Wabcontrol.
ETR 460s can carry up to 480 passengers. Configuration includes two head coaches, 6 intermediate passenger coaches and a bar - restaurant coach.
A tilting train is a train that has a mechanism enabling increased speed on regular rail tracks. As a train rounds a curve at speed, objects inside the train experience centrifugal force. This can cause packages to slide about or seated passengers to feel squashed by the outboard armrest, and standing passengers to lose their balance. Tilting trains are designed to counteract this by tilting the carriages towards the inside of the curve, thus compensating for the g-force. The train may be constructed such that inertial forces cause the tilting, or it may have a computer-controlled powered mechanism.
The Advanced Passenger Train (APT) was a tilting high speed train developed by British Rail during the 1970s and early 1980s, for use on the West Coast Main Line (WCML). The WCML contained many curves, and the APT pioneered the concept of active tilting to address these, a feature that has since been copied on designs around the world. The experimental APT-E achieved a new British railway speed record on 10 August 1975 when it reached 152.3 miles per hour (245.1 km/h), only to be surpassed by the service prototype APT-P at 162.2 miles per hour (261.0 km/h) in December 1979.
Pendolino is an Italian family of high-speed tilting trains used in Italy, Spain, Germany, Poland, Portugal, Slovenia, Finland, Russia, the Czech Republic, Slovakia, the UK, the US, Switzerland, China, and Greece. Based on the design of the Italian ETR 401, it was further developed and manufactured by Fiat Ferroviaria, which was taken over by Alstom in 2000.
SŽ series 310 is a high-speed tilting EMU used on the InterCitySlovenija premium train service in Slovenia, operated by Slovenske železnice since September 24, 2000. It is based on the Italian ETR 460 commonly known as Pendolino. The train is capable of reaching a maximum speed of 200 km/h. The train is electric single system - 3 kV DC.
Cisalpino AG was a railway company, referred to as CIS in timetables, operating international trains between Switzerland and Italy connecting Basel, Schaffhausen, Zürich, Geneva, Milan, Venice, Trieste, Livorno, and Florence. The company has its legal headquarters in Muri bei Bern (BE), Switzerland, and is jointly owned by the Swiss Federal Railways and Trenitalia.
The Italian railway system is one of the most important parts of the infrastructure of Italy, with a total length of 24,227 km (15,054 mi) of which active lines are 16,723 km. The network has recently grown with the construction of the new high-speed rail network. Italy is a member of the International Union of Railways (UIC). The UIC Country Code for Italy is 83.
Eurostar Italia was the name given to high-speed trains operated by Trenitalia in Italy. The brand was discontinued and replaced with Le Frecce in December 2012.
Alfa Pendular is the name of the flagship Pendolino high-speed tilting train of Portuguese state railway company CP. It connects the cities of Guimarães, Braga, Porto, Aveiro, Coimbra, Santarém, Lisbon, Albufeira and Faro, among others at speeds of up to 220 kilometres per hour (137 mph).
ETR 450 was the first series Italian tilting train.
The New Pendolino is a class of high-speed tilting trains built by Alstom Ferroviaria for Trenitalia and Cisalpino.
ETR is a series of Italian high-speed trains.
The FS E.645 and E.646 are two classes of similar electric locomotives used on Italian railways. They were introduced during the 1950s and they were retired in 2009.
Alstom Ferroviaria S.p.A., formerly known as Fiat Ferroviaria S.p.A., is the Italian division of Alstom. Fiat Ferroviaria S.p.A. was the rail division of automobile manufacturer Fiat. It was founded in 1880 as Società Nazionale Officine di Savigliano. Fiat Ferroviaria began building locomotives in the 1930s. It became part of Fiat in 1970. Fiat Ferroviaria acquired the rail business of SIG of Switzerland in 1995, forming the subsidiary Fiat-Sig.
ETR 470 is a high-speed tilting electric multiple unit, which is now only operated by the Greek company, Hellenic Train. Introduced in September 1996, nine units were built for the Italo-Swiss firm Cisalpino. They were made by Fiat Ferroviaria, and could tilt up to 8°. Today, there are five trains in Greece.
The Sm3 Pendolino is a class of high-speed body-tilting trains operated by VR Group. It is a member of the Pendolino train family; its design is based on the ETR 460. The first two trainsets were assembled in Finland by Rautaruukki-Transtech in the mid-1990s. The rest of the series of eighteen EMUs were built by Fiat Ferroviaria between 2000 and 2006. The trains serve most of Finland's major cities such as Helsinki, Turku, Oulu and Joensuu with a maximum speed of 220 km/h (140 mph), although this speed is only attained between Kerava and Lahti. The train has a power output of 4,000 kW (5,400 hp) and weighs 328 tonnes.
The ETR 480 is a tilting Electric Multiple Unit built by Fiat Ferroviaria since 1993, It is also known as Pendolino. It was developed from the first new-generation Pendolino, the ETR 460. The main difference between ETR 460, ETR 470 and ETR 480 is that the 460 run only on 3 kV DC, the 470 on both 3 kV DC and 15 kV AC, and the 480 on both 3 kV DC and 25 kV 50 Hz AC.
ČD Class 680 are EMUs operating in the Czech Republic, using tilting Pendolino technology intended for the SuperCity train service. Built by Alstom, they were largely based on the nine-car ETR 470. While testing from Břeclav to Brno on November 18, 2004, the Pendolino reached a speed of 237 km/h (147 mph) and created a new Czech railway speed record. The units are able to operate on 25 kV 50 Hz AC, 15 kV 16.7 Hz AC and 3,000 V DC.
The Renfe Class 490, also known as the ETR 490, is an electric multiple unit constructed by Alstom and Fiat Ferroviaria and operated by Spanish rail company Renfe on its Alaris long-distance services. Since the introduction of the Alaris service, only ETR 490 units have been used for this service. Therefore, these trainsets are often known as Alaris themselves. The units were the first actively tilting units to go into regular service in Spain.
