Zefiro 250 The first variant of the Zefiro concept to be produced was a series of twenty 16-car EMU sleeper trains produced by Bombardier's joint venture
Sifang Power (Qingdao) Transportation (BSP), which were delivered from 2009. These trains were the first high-speed train licensed to be manufactured in China as well as the fastest sleeper trains in the world. China Railways designated them as CRH1E. In September 2012, based on a modified contract with Bombardier, the MOR ordered an additional 106 8-car trains, 60 of which are to be a new variant, designated the Zefiro 250NG. This variant is an evolution of the original, and will utilize different materials in order to provide weight savings and more efficient operation.
Zefiro V300 }} The Zefiro V300 is intended for European operations, with a
UIC profile, and capable of being fitted for use on all four European electrification schemes (1.5 & 3 kV DC, 15 & 25 kV AC). Bogies are FLEXX type with a wheelbase, Trenitalia selected this bid as the winner on 5 August 2010. These entered service in 2015 and are designated
Frecciarossa 1000. An evolution of the Zefiro V300 platform was also offered by a joint venture between Bombardier (later Alstom) and
Hitachi Rail for the
HS2 rolling stock tender for its first phase, for which it was awarded the contract for 54 trainsets and will be classified as the
Class 895.
Zefiro 380 In September 2009, Bombardier announced an order for eighty Zefiro 380 high-speed trains by the
Chinese Ministry of Railways (MOR) to be produced at Bombardier's joint venture
Sifang (Qingdao) Transportation Ltd. The order of twenty 8-car sets and sixty 16-car sets was estimated to be worth 27.4 billion
RMB (approx €2.7 billion or $4 billion). The value of Bombardier's share is estimated at €1.3 billion. Under China Railways' use these trains have been designated CRH1C (8-car set) and CRH1D (16-car set). which was in December 2010 revised to CRH380C and CRH380CL and once again to
CRH380D (8-car set) &
CRH380DL (16-car set) according to the new numbering system. As of September 2012, the order has been amended to include only seventy 8-car sets, designated as the CRH380D and additional 46 Zefiro 250 and 60 Zefiro 250NG. They have three cars and are around long. First delivery was planned at end of 2021, but the coronavirus pandemic has delayed the production and test runs of the new trains. Västtrafik then expected that the first train set will arrive in Västerås in April 2022, and that another four train sets will be delivered to Sweden during the spring. The first vehicles were due to be operating in the traffic in spring 2024 The trains are designed for the colder weather conditions under which the fleet will operate, including temperatures as low as -40 degrees Celsius and snow drifts up to 80 cm deep. They are equipped with a winter package including an uprated propulsion system, a single-axle drive and enhanced slip-slide regulation. The bodyshells were manufactured by Bombardier Sifang (Qingdao) Transportation Ltd in China with final fit-out of all other components performed at the
Hennigsdorf works in Germany. The trains have been thoroughly temperature tested already, and will be tested further in Sweden during winter 2022. In late 2025, entry into service was further delayed by at least six months due to software issues, pushing their planned entry into service to April 2026.
SJ 250/X250 (Delta 2.0) In 2021, the Swedish train operator
SJ decided to buy 25 new Bombardier/Alstom Zefiro trains, expected to come into service in 2026. The top speed is . The trains will have 363 seats, and designed to handle running at temperatures of -40 degrees Celsius. Train systems are designed to operate in both Sweden and Denmark, as well being certified to operate in Norway. ==See also==
