DIAMOND have also recently been using some 2011 E400s on the 149, as well as their StreetDecks ( - some of which are in "wraps").
On some days recently FIRST Worcester have managed to use all 19 of their E400s, whereas a lot of single-deckers have not been in service or tracked (bustimes).
Yesterday First used a DD on the 31A / 31 for the first time - following on from the AM 333/332 which looks set to be a regular DD now.
Other recent "DD exotica" has included the AM 334 yesterday, and a couple of early AM 35s !!! - albeit only Dines Green to Crowngate (to avoid decapitations).
ALSO, reported on Facebook is an exchange of First DDs between "Up-North" depots and Welsh depots, being done via Padmore Street !
