Opted to rebuild the station (5)
I believe the answer is:
depot
'station' is the definition.
(depot is a kind of station)
'opted to rebuild' is the wordplay.
'to rebuild' is an anagram indicator (I've seen 'rebuilding' mean this).
'opted' anagrammed gives 'DEPOT'.
'the' is the link.
(Other definitions for depot that I've seen before include "Opted (anag)" , "Bus station or warehouse" , "Toped (anag.)" , "Terminus for transport vehicles" , "(Military) store" .)
