The next vehicle to be used as a demonstrator on the X1 arrived on Thursday and should enter service on the 07.23 Dereham - Peterborough on Monday morning if all goes according to plan. It is a Triaxle version of the Ensign double decker which was on loan in late June and early July, here are the pictures from my man on the spot at First :
I will do an update on the last few months trials and tribulations with the Enviro fleet this month.
