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' indicates anagramming the letters (I've seen 'rebuilding' mean this).
'opted' is an anagram of 'DEPOT'.
'the' acts as a 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" .)
