Firstly this is the first body to be welded at Newton Aycliffe. And it is taking longer than expected per vehicle to complete.
I was under the impression that the Avanti 805/807 build was the first to weld car bodies locally at Newton Aycliffe.
Slightly confusing because the local build was specified as "around half" of it, so it's uncertain which units are welded locally, and which in Japan.
So it's possible all those delivered to Avanti so far used Kasado-built car bodies.
And the Avanti build, of which about half has been delivered, is also very late compared to the original contract.
There is also the anti-cracking modification to be applied at some point to the Avanti and EMR fleets.
