Still very surprised that these along with the Fab 56 B9s weren't replaced with StreetDecks with all of the B9s going X-Lines. The B9s in my opinion are more suitable than the StreetDecks particularly on the extended X21 as well as the X47/X70/X71.
Bloody hell, they not even been delivered and tour already slating them
