I would say from that article it looks like Hitachi are playing the Bombardier card already, it may be poor journalism but I see they've already found themselves quoted as "The Newton Aycliffe based firm". Since when did Hitachi move HQ from Japan to the North East? The same toy throwing comment has been banded around Bombardier for many a year, with them labelling themselves as "The Derby based Firm", obviously French-Canadian Headquartered in Berlin doesn't have the same ring to it.
It's also a bit rich of Hitachi to start throwing their toys out of the pram at another manufacturer choosing to start production of it's rolling stock abroad while it's factory is under construction - I would say Hitachi have rather got themselves into the mess they've created by choosing to produce it's UK orders as quickly as possible, spread over 3 factories. The First Group ordered 802s could have been built in Newton Aycliffe for example, rather than the former Ansaldo facility as Pistoia - there was less of a rush for those. In fact, I'm led to believe that that is where the Hull Trains and Trans Pennine orders are also currently coming from as well. Not forgetting that the first UK orders was built in Hitachi's factories in... Japan as NA wasn't ready.
So it looks like we're now going to have Hitachi and Bombardier throwing it's toys out of the pram each time they lose an order, just because the preferential treatment is running out. Bombardier however at least seem to be keeping quiet as of late in relation to TfL matters... I couldn't think why!
