The Solution is: Things associated with London

The category "Things associated with London" unites all five clues through a shared association. Each clue connects differently: The Underground → London Underground, Double-decker buses → Red double-decker buses, The Thames → River Thames, Big Ben → Big Ben clock tower. The challenge is thinking thematically rather than structurally — these words don't form compounds but evoke the same concept.
