HS2 Ltd shortlisted Alstom, Bombardier Transportation, Hitachi Rail Europe, Talgo and Siemens to bid for the contract in November 2017. However, HS2 Ltd has now invited CAF to join the list of shortlisted bidders so there will still be five bidders when HS2 Ltd invites the companies to tender later this year. The contract is expected to be awarded in late 2019 and the fleet must be operational by 2026 in time for the opening of the high-speed line.\r\n\r\nThe new trains must be compatible with Britain\u2019s restrictive loading gauge to enable through operation on conventional lines north of Birmingham.\r\n\r\nThe winner of the contract will maintain the fleet at a new depot to be built at Washwood Heath in Birmingham, which will also be the location of the HS2 control centre.\r\n\r\nBombardier and Hitachi collaborated on the production of a fleet ETR 1000 high-speed trains for Trenitalia as a result of Hitachi\u2019s acquisition of AnsaldoBreda. Hitachi supplied a fleet of class 395 Javelin 225km\/h trains for operation of domestic services on HS1 linking London with Ashford, and is currently supplying 200km\/h class 800\/801 trains for Great Western Railway and London and North Eastern Railway under Britain\u2019s \u00a35.7bn Intercity Express Programme.\r\n\r\nThe two companies say that responsible procurement, in terms of long-term employment and reducing environmental impact, will be a cornerstone of their bid. \u201cThe ETR 1000 train used 85% recycled materials and the joint bid for HS2 would deploy the latest noise reduction technology,\u201d they said.\r\n\r\nCAF says it intends to offer its Oaris high-speed train when it submits its bid. "CAF plans to build the trains in its manufacturing facility currently being constructed in Newport, Wales," says Mr Richard Garner, CAF's UK director.
