Public transport cut — complaint of the countryside (7)
I believe the answer is:
bucolic
'of the countryside' is the definition.
'public transport cut complaint' is the wordplay.
'public transport' becomes 'bus' (bus is a kind of public transport).
'cut' means to remove the last letter.
'complaint' becomes 'colic' (medical complaint**).
'bus' with its final letter taken off is 'bu'.
'bu'+'colic'='BUCOLIC'
(Other definitions for bucolic that I've seen before include "Pastoral poem" , "Relating to rural life" , "Rustic - pastoral" , "Characteristic of country life" , "Of rural or pastoral life" .)
