Confirmed registrations of the new Streetlites to date available here
Note that 1560 is registered with the prefix 'NK14' opposed to 'NK64', meaning that there will be a split somewhere although where isn't known just yet (I'll update accordingly as/when the details emerge).
1567 is likely to be NK64EFD.
Richard Smiles reports that 1563, 1569 & 1570 were at Heysham Docks on Sunday & at least 1563 has arrived at Jesmond.
