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. 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. The electric multiple units (EMUs) 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.
The trains are designed to be 'conventional compatible', capable of leaving the dedicated high-speed sections to continue onto existing lines, and will be gauge-compatible with its planned operational routes where the loading gauge would be more restricted.
