Why only outer terminal?
Do you already know about the 109, which used to loop along the
Embankment between Westminster and Blackfriars bridges for its inner
terminal?

Hadn't considered the possibility of such a routeing at the Inner
London end. What did the buses show as their destination on the way to
the "loop" and was there a recognised point on the loop for the blinds
to be changed and layover taken?
