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.[12] These trains were the first high-speed train licensed to be manufactured in China as well as the fastest sleeper trains in the world.[13] China Railways designated them as CRH1E.[14]

Starting acceleration is greater than 0.6 m/s² (2.0 ft/s²), with a 16-car train weight of 859 t (845 long tons; 947 short tons) and an axle load of 16.5 t (16.2 long tons; 18.2 short tons), bogie type is that found on the Regina (train) with 2.7 m (8 ft 10 in) wheelbase with 63% of axles motorized.[15]

In July 2010 The Ministry of Railways ordered 40 more 8-car 250 km/h (155 mph) CRH1E Zefiro high-speed trains from the Sifang (Qingdao) Transportation Ltd joint venture.[16]

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.[17]

In 2018 Swedish regional transport agency Västtrafik ordered 45 Bombardier Zefiro for delivery 2021. They will be designed and approved for 200 km/h. They have 3 cars and are 80 meters long.

The Zefiro 300 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 2.85 m (9 ft 4 in) wheelbase,[15] 50% of which are motorized. Starting acceleration is greater than 0.60 m/s² (2.0 ft/s²). It has an axle load of approximately 17 t (16.7 long tons; 18.7 short tons).[15] Two 8-car sets can be joined together to form one longer train.[15]

A variant of the Zefiro 300 was offered by Bombardier in association with AnsaldoBreda to Trenitalia, the Italian national railway service, as part of a bid for 50 new high-speed trainsets in 2010.[19] Trenitalia selected this bid as the winner on 5 August 2010.[20] These entered service in 2015 and are designated ETR400 - Frecciarossa 1000.[21]

An evolution of the Italian version of the Zefiro 300 was also offered by Bombardier (joined with Hitachi Rail) for High Speed 2 commercial tender.

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. [23][24]

Under China railways use these trains have been designated CRH1C (8-car set) and CRH1D (16-car set).[14] 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.[25]

As of the most recent news, the order has been amended to include only seventy 8-car sets, designated as the CRH380D. Orders for the 16-car DL sets were converted to D sets in late 2011.[17]

All the 85 trainsets have been delivered and are currently operated by Shanghai Railway Bureau & Chengdu Railway Bureau.

Swedish regional transport authority Västtrafik ordered 40 new trains in 2018, later increased to 45 trains, of a new model capable of 200 km/h. They will have three cars and be around 80 meters long. First delivery is planned to end of 2021.[26][27]
