Selkent : TB for their excellent presentation of vehicles. They obviously take pride in clean buses.
London United : FW , historic and childhood reasons mainly. Grew up riding on their former Metrobuses on the 33,90b,110,267,270,281,285 & 290
Metroline : PB , only former LT shed outside the London boundary
London General : AF , nice routes
Arriva : N , nice routes and out of all the Arriva London South sheds, best presentation of buses
London Central : BX because it came back from being closed to a garage full up . Don't like the single deck routes though.
Abellio : Would have to be TF but only because the site is so historic and i am pleased it remains a bus garage. Would rather London United be in charge of it though !
East London : BW , nice garage , old design , interesting routes.
Arriva North : AD , seems like a nice close knit shed
Tower Transit : X , unique because a motorway runs over the top of it.
