Currently sat behind some Avanti technical staff (well, they were discussing ETCS overlays and ERTMS so I assume they must be!).
Apparently 9 units have been accepted by Avanti so far.
There have also been issues with SDO where the train knows where it is, but doesn't know what service it's on (I don't really understand why this should matter?) and refuses to open the doors at some station meaning the driver must manually select the doors to release.
First class catering in full force today with very kind and attentive staff.
