Track force (8)
I believe the answer is:
railroad
I believe this clue is a double definition.
'track' is the first definition.
(railroad track is a kind of track)
'force' is the second definition.
(railroading is a kind of forcing)
(Other definitions for railroad that I've seen before include "Bully" , "[DRAGOON]" , "Coerce (someone) into doing something" , "Push through unduly" , "US term for train line" .)
