Boards a coach (5)
I believe the answer is:
stage
I believe this clue is a double definition.
'boards' is the first definition.
(I've seen this before)
'a coach' is the second definition.
(stagecoach)
(Other definitions for stage that I've seen before include "Form of transport" , "Support for acting" , "Performance place" , "Section (of journey)" , "Rostrum" .)
