\r\nHitachi will offer its AT400 classic-compatible train which would be a 200m-long eight-car train mounted on bogies and designed for 360km\/h operation. \u201cOur concept for HS2 is very fluid,\u201d Mr Jim Bowen from Hitachi told IRJ. \u201cIt will be a bespoke product for which we are trying to maximise our supplier chain.\u201d\r\nTalgo is developing its Avril UK concept for operation within the restrictive British loading gauge. This means the British train would only have two-plus-two seating compared with three-plus-two for the Spanish version of Avril which Talgo is supplying to Renfe under a contract awarded in November 2016.\r\nAvril UK would retain Talgo\u2019s articulation system, which avoids the use of conventional bogies. However, while the Spanish version has power cars the British variant would have distributed traction.\r\nAn invitation to tender for the contract to supply 54 high-speed trains will be issued in the first quarter of next year with a view to awarding the contract by the end of 2019.
