Bus route N11.

Well spotted!

Someone has evidently seen "Ludgate Circus National Rail symbol" on
the list of N11 stops (e.g. at http://www.busmap.org/tt/N011.pdf ), and
hasn't realised it means Ludgate Circus for City Thameslink station.
They didn't make the same mistake with Trafalgar Square, though.
