Transport lobby, maybe (8)
I believe the answer is:
entrance
I believe this clue is a double definition.
'transport' is the first definition.
(I've seen this before)
'lobby maybe' is the second definition.
(lobby can mean an entrance hall)
(Other definitions for entrance that I've seen before include "Ingress" , "Capture" , "Opening to allow access" , "Charm - one's way in" , "An actor's coming on stage" .)
