Clever turn-around for public transport (5)
I believe the answer is:
trams
'for public transport' is the definition.
(I've seen this before)
'clever turn' is the wordplay.
'clever' becomes 'smart' (similar in meaning).
'turn' is a reversal indicator.
'smart' reversed gives 'TRAMS'.
'around' is the link.
(Other definitions for trams that I've seen before include "silk yarns" , "old vehicles" , "public transport" , "Not seen in London" , "People movers" .)
