The Class 374 consists of eight car half-sets which operate in pairs with the two driving cars at either end. The Class 374 is part of Siemens Velaro high speed train family though with the traction equipment distributed throughout the train for safety whilst travelling in the Channel Tunnel (this has also allowed the 374 to have a greater passenger carrying capacity than the 373). This safety requirement was key to Alstom when they challenged Eurostar awarding Siemens the contract saying the Velaro broke Channel Tunnel safety rules. However the European Commission rejected this argument and Alstom dropped their legal action.
The original order was for ten sets though an extra seven sets was ordered later on. The Class 374 entered service in 2015, the first of the new extended routes through to Amsterdam was launched in April 2018 .
