4644 was working the X66 out of Middlesbrough around 0915
The X66 I saw was a Pulsar.
In a bizarre twist 4645 is on the next 26A to Colburn.I think the Pulsar was 1428. Rather odd that these two Omnicitys were out today, I was expecting it to be all Pulsars today. No idea what the other bus was as I didn't see any bus on the 1130 X66 journey out of Darlington.
Is it possible that some Pulsars may have been off to have the next stop announcements sorted?
