New Pendolino

The New Pendolino is a class of high-speed tilting trains built by Alstom Ferroviaria ( Fiat Ferroviaria) for Trenitalia and Cisalpino. It is derived from a model developed for the Chinese operator Changchun Railway Company, and subsequently developed for other railway companies, optionally using the variable weight technology that characterizes this family of trains.

Overview

The name ''Pendolino'' is used to identify a family of high-speed, tilting-technology trains, produced in Italy. These trains owe their name (''pendolino'' can mean 'small pendulum' in Italian) to the mechanism enabling them to tilt when going round a curve. The maximum tilt of 8 degrees allows the trains to reach a speed that is up to 35% higher than for conventional trains whilst remaining comfortable for passengers. Developed by Alstom Ferroviaria, which inherited tilting technology (including that of the British Advanced Passenger Train) after its acquisition of former producer Fiat Ferroviaria, they are built at Alstom's Savigliano plants, in Piedmont, as well as in Sesto San Giovanni near Milan (which will supply the traction converters).

The Pendolino first began service in Italy in 1988, with model ETR 450, followed by ETR 460, ETR 470 and ETR 480. A new model generation was launched in 2006 with ETR 600 for Trenitalia and ETR 610 / RABe 503 for Cisalpino, a railway company that operated trains between Switzerland and Italy. Manufacturer Alstom labeled them as ''New Pendolino''.

ETR 600-610 (Italy) / RABe 503 (Switzerland)

The ETR 610 / RABe 503 (also known as the Cisalpino Due as it was the second class of tilting trains used by Cisalpino) primarily differs from the ETR 600 in the sense that the ETR 610 / RABe 503 supports the voltage and signalling systems used in Switzerland and Germany. This includes the need for much heavier on-board traction power transformers necessary as a result of the lower traction power frequency of 16.7 Hz used in Switzerland and Germany in comparison with those required for the 25 kV 50 Hz AC traction power supplies. The innovative features concern the interior and exterior design, now closer to the customers’ brand strategy and an improved comfort and services for passengers. Moreover, some important technical characteristics have been increased, such as the power of the traction unit and the level of redundancy of components and equipment, in order to improve reliability. The new trains will be produced in full accordance with the new regulations governing interoperability (for example, passive security in case of impact). The train is run on international routes from Switzerland to Italy and starting with the December 2017 schedule change one daily trip from Frankfurt (Main) Hauptbahnhof to Milano Centrale via the Gotthard Base Tunnel and back via Simplon Tunnel and Lötschberg Base Tunnel to Frankfurt.

ED250 (Poland)

On 30 May 2011 the Polish state railways PKP signed an agreement with Alstom for 20 Pendolinos ETR 610 for delivery in 2014. The first Pendolino was delivered on August 12, 2013. The new trains, called Pendolino ED250, will operate on the route from Gdynia to Warsaw, on the high-speed CMK Central Rail Line from Kraków/Katowice to Warsaw and Wrocław to Warsaw.

Polish "Pendolino" trainsets do not have tilting mechanism which precludes them from the main advantage of faster taking of curves.

High speed tests using the new Pendolino ED250 on the CMK Central Rail Line began in November 2013. On the first day of tests, November 16, the Pendolino reached . On 17 November 2013 a new speed record for Polish railways was set when the Pendolino ED250 reached a speed of , breaking the 19-year record of . On 24 November 2013 the final day of tests on the CMK Central Rail Line the Pendolino reached .

The contract between the Polish operator PKP Intercity and Alstom called for the first eight Pendolino ED250 trainsets to be delivered on 6 May 2014, tested ('homologated') for operation at using ETCS L2 signalling. The tests had not been performed by May, and PKP announced that Alstom had failed to meet the contract terms and would be charged penalties as of May 6. Alstom responded that homologation in Poland at using ETCS Level 2 was impossible, since ETCS Level 2 was not operational anywhere in Poland, and the Central Rail Line (Poland) where the first ED250 Pendolino had reached in testing was equipped with ETCS Level 1, not Level 2. On 26 June 2014 a compromise was reached between PKP and Alstom under which the Pendolinos would be delivered under a two-stage homologation, first homologated for operation using ETCS Level 1 and eventually to be homologated for ETCS Level 2. Hopes were expressed that the Pendolinos could be in service by 14 December 2014.

As of 2020/21 timetable, ED250 operate with scheduled speed of up to on selected stretches of the Warszawa - Gdynia and Central Rail Line routes.

In 2020 one train did derail in Germany during an instrumented test run.

Avant S-114 (Spain)

The Avant S-114 is a four-car variant of the New Pendolino design, and much like the Polish version is not fitted with tilting mechanisms.

The thirteen trainsets are now used on high-speed services between Madrid, Segovia, and Valladolid, on the high-speed line.

ETR 675 (Italy)

The new Pendolino EVO ETR.675 of NTV is part of the ''Avelia'' family of Alstom, which also includes other convoys distributed in different countries of Europe.

The Pendolino ETR.675, like the one PKP, is not equipped with variable attitude. The name Pendolino, however, evidently remains as a brand for trains that can be structured both with and without oscillation.

CRH5A (China)

China Railway High-speed (CRH) purchased technologies from Alstom to assemble 60 sets of high speed EMU trains, which have been named CRH5 and are based on the New Pendolino trains. The CRH5 are non-tilting trains. 30 additional sets were ordered in 2009 and 20 additional sets was ordered in 2010 to complete the current fleet operating on China's northern and eastern lines.
