Heritage Routemaster RM2071 (reg. ALM 71B) pictured in Byward Street in the City of London. It's waiting for the lights to change while in the small section of bus lane in the middle of the dual carriageway, which is there to allow buses to cross the oncoming traffic to turn right into Great Tower Street (note the flashing mid-level indicator lamp). At this point on the route it's only recently begun a new westbound journey of heritage route 15, to Trafalgar Square. It's the early evening, so this is quite possibly the last bus of the day for the heritage version of the route.
