Mountain transport (5,3)
I believe the answer is:
cable car
'mountain transport' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for cable car that I've seen before include "Transport used to go up mountain" , "Means of mountain transport" , "Clear cab for carriage used by ascending skiers" , "Suspended transport system" , "Mountain transport system" .)
