In the later phase 2b, a number of 'captive' trains (unable to use the existing rail network) may be ordered to operate alongside the conventional compatible trains, with a similar loading gauge to existing European high speed trains.

History

A modelling of costs and risks in the project in 2012 estimated that captive trains may cost around £27million per train and the conventional compatible trains, which will be built for the United Kingdom

, could have cost around £40million. The first batch of

Five bids were shortlisted for the first HS2 rolling stock contract: *

We humbly believe that Talgo’s combination of experience and adaptivity is the best option for both train operating companies and taxpayers.” * Siemens, a German company. William Wilson, CEO of Siemens Mobility has said “Our team has worked tirelessly to develop an offer that transforms how passengers experience high-speed trains and set the standard for other global high-speed rail systems to follow." On 9 December 2021, the contract was awarded to the Hitachi Rail-Alstom joint venture. There have been reports of legal challenges related to the contract. A challenge by Talgo was settled out of court. Siemens sought an injunction to stop the contract being awarded but is now only seeking damages. It has been reported that this is to help it secure contracts for other elements of the HS2 project. The contract was to be awarded in spring 2020, but was delayed due to delays to the start of HS2 construction. The contract was then scheduled for October 2021 but was not awarded until December 2021 as it awaited government approval.

Initial train class

The contract to build the trains for the 54 conventional compatible trains for phases 1 and 2a is worth £1.97billion, 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). 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

. The first train will finish production around 2027. They will enter service when phase 1 and 2a of HS2 opens between 2029 and 2033. 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. The trains will also be the fastest trains in the United Kingdom and Europe. 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.
