4.1 Through CAF, we completed manufacture and static testing of the first train three months ahead of programme, and have now completed manufacture of the first four trains. We expect to complete manufacture of 12 trains by the end of the financial year.
4.2 The first two trains commenced dynamic testing on the manufacturer’s test track in Spain three months ahead of programme. This involves type tests of the onboard systems followed by 20,000km fault free endurance testing to prove reliability. This testing is forecast to conclude by the end of 2022 and the trains will then be delivered to the UK for network testing.
4.3 There have been some issues with the integration of the Thales on board signalling software which have been successfully mitigated to date. Significant risk remains in this area of the programme, however, with limited remaining mitigations and so this remains a key area of focus for the RSRP
