Move rapidly to get coal container (7)
I believe the answer is:
scuttle
This clue is a double definition.
'move rapidly' is the first definition.
(synonyms)
'coal container' is the second definition.
(I've seen this before)
'to get' acts as a link.
(Other definitions for scuttle that I've seen before include "coal carrier" , "Sink with cutlets" , "Move hurriedly" , "fuel container" , "make a dash for it!" .)
