The initial order was for 'conventional compatible' trains, able to run at the top operational speed of 360 km/h (225 mph) on the HS2 line. These will be 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. 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.
The contract for the first batch was awarded to a 50/50 joint venture between Hitachi Rail and Alstom, for 54 conventional compatible trains, which will be constructed in the United Kingdom. The trains will be based on an evolution of the Zefiro V300 platform. 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.
