I apologise if this is a stupid question but I've heard it mentioned a lot so I'm wondering, what is E334?

it's a ADL enviro400EV

ADL E400EV seed vehicle, kinda like a demo but its built for a specific operator in their spec.
Arriva has AR74 ZEB (Currently at leicester)
Stagecoach has SC74 ZEB (Currently at Dunfermline)
First has FB74 ZEB (Currently at Doncaster)
Go Ahead has GA74 ZEB (Not in service yet, but at GSC.)
then now national express should get NX74 ZEB, to be E334.

E301 finally entered service last night after complications fitting the radio, so PB now has a full allocation of the planned 116 buses
