Ah many thanks for the info below
None delivered and none have left Aycliffe factory. I was on visit to factory last week, trains up to T14 were visable in various build states. Unlike IEPs where 1 per week is being delivered, Hitachi said that they are contracted to deliver a set quantity on certain dates, i think it was 10 complete units by October.
A few key dates:-
August - Mandatory testing due to be completed.
September - Commisioning starts from Craigentinny
October - Around 60 Abellio Scotrail drivers start training
November - Type Approval due
December - 21 trains delivered to ASR.
