The HS2 rolling stock are trains for the under-construction High Speed 2 (HS2) high-speed rail line in the United Kingdom.
The contract was awarded to a 50/50 joint venture between Hitachi Rail and Alstom, for 54 trains, which will be constructed in the United Kingdom. [8] The trains will be based on an evolution of the Zefiro V300 platform and able to run at the top operational speed of 360 km/h (225 mph) on the HS2 line. [9] [10] The electric multiple units (EMU) will be 200-metre (656 ft 2 in) long with the option to couple two units together to create a 400-metre (1,312 ft 4 in) train. [11]
The trains are designed to be 'conventional compatible', capable of leaving the dedicated high-speed sections to continue onto existing lines, [12] and will be gauge-compatible with its planned operational routes where the loading gauge would be more restricted. [10]
A modelling of costs and risks in the project in 2012 estimated that captive trains may cost around £27 million per train and the conventional compatible trains, which will be built for the United Kingdom loading gauge, could have cost around £40 million. [13]
The order for rolling stock for HS2 is specified in the Train Technical Specification issued with the Invitation To Tender (ITT), which was initially published in July 2018, being revised in March 2019 following clarification questions from tendering companies. [10]
Five bids were shortlisted for the first HS2 rolling stock contract: [14]
In the previously planned phase 2b, a number of 'captive' trains (unable to use the existing rail network) may have been ordered to operate alongside the conventional compatible trains, with a similar loading gauge to existing European high speed trains. [12]
On 9 December 2021, the contract was awarded to the Hitachi Rail-Alstom joint venture. [16]
A legal challenge by Talgo was settled out of court. [17] Siemens sought an injunction to stop the contract being awarded but is now only seeking damages. [18] It has been reported that this is to help it secure contracts for other elements of the HS2 project. [19]
The contract was to be awarded in spring 2020, but was delayed due to delays to the start of HS2 construction. [20] The contract was then scheduled for October 2021 but was not awarded until December 2021 as it awaited government approval. [20]
The contract to build the trains for the 54 conventional compatible trains is worth £1.97 billion, which includes an initial 12-year maintenance contract for the trains, with the option to extend this to the design life of the trains (of 35 years). [21]
Vehicle body assembly and initial fitting out of the trains will take place at the Hitachi Newton Aycliffe factory, the bogies will be manufactured at the Alstom factory in Crewe, and final assembly and fit-out, including the interiors, electronics and bogies, will take place at Alstom's factory in Derby. [22] [23]
The first train will finish production around 2027. [16] They will enter service when phase 1 and 2a of HS2 opens between 2029 and 2033. [1]
The trains will feature regenerative braking and Hitachi Rail's low noise pantograph, whilst also being 15% lighter and feature 30% more seats than comparable high speed trains in Europe. [24] [20] The trains will also be the fastest trains in the United Kingdom and Europe. [8]
The interior layout will be decided following a two and a half year design process involving HS2 Ltd, the Department for Transport and the West Coast Partnership.
The trains became the first in the world to achieve the BSI's PAS 2080 global accreditation for meeting environmental targets to reduce carbon emissions, such as by improving aerodynamics, using energy-efficient traction systems and lightweight, recycled content. [25]

High Speed 2 (HS2) is a high-speed railway line which is under construction in England. The same name is planned to be used for services which are to run on the line and beyond. The line is to run between Handsacre, in southern Staffordshire, and London, with a spur to Birmingham. A network of new train services is planned, which are to use the new line and existing conventional track to reach their destinations in the Midlands, North West England, and Scotland. HS2 is to be Britain's second purpose-built high-speed line after High Speed 1, which connects London to the Channel Tunnel. A review of the line's route is currently being undertaken with a report expected in Summer 2024, which concluded in March 2024 that the leg between Birmingham and Manchester would be funded by private investment, by the Mayors of Greater Manchester and the West Midlands. The majority of the project is planned to be completed between 2029 and 2033.
The Intercity Express Programme (IEP) is an initiative of the Department for Transport (DfT) in the United Kingdom to procure new trains to replace the InterCity 125 and InterCity 225 fleets on the East Coast Main Line and Great Western Main Line. These new trains would be built by Hitachi as part of their A-train family, classified as Class 800 electro-diesel units and Class 801 electric multiple units. Hitachi designated the units as the AT300 family, which is their Intercity High Speed fleet. Other AT300 units have also been ordered for other train operating companies, which are not part of the IEP.

Construction started in 2013 at a cost of £82 million, with train assembly commencing in 2015. It was the first factory that Hitachi built in Europe, as a result of it winning the Intercity Express Programme tender. Originally on opening, no actual manufacturing operations took place at the site; it assembled components built elsewhere into completed trains. However, for the later classes, some manufacturing took place on site. By October 2017, the plant employed over 1,000 members of staff.
Siemens Goole is a train factory located in Goole, East Riding of Yorkshire, England. Siemens Mobility assessed several sites in the United Kingdom before settling on Goole with an intent to build the plant if it were successful in gaining orders for new rolling stock. After a June 2018 announcement that Siemens had won the bid to build 94 London Underground New Tube for London trains for the Piccadilly line of the London Underground, Siemens confirmed it would go ahead with building the factory, though this was then subject to further delays as other rolling stock companies objected to Siemens being given the contract.
