RM on the 22!

Had a bit of a surprise today while in the Putney region monitoring the 14 after its extension the short way beyond Tottenham Court Road to Warren Street – its former partner in crime, the 22, hosted an RM!
RM 848 (448 UXS, ex WLT 848), which saw out its service career at Clapton on the 38 and is now privately owned, was doing short runs to Sloane Square in conjunction with an exhibition held by Will’s Art Warehouse, an art gallery at Putney Common. I didn’t know a Routemaster was involved, so I was lucky to be on hand when I saw it emerge from Lower Richmond Road at 3:35.
