Near disastrous time invested in Virgin transport (9)
I believe the answer is:
enrapture
'transport' is the definition.
('enrapture' can be a synonym of 'transport')
'near disastrous time invested in virgin' is the wordplay.
'disastrous' is an anagram indicator.
'time' becomes 't'.
'invested in' means one lot of letters goes inside another.
'virgin' becomes 'pure' ('pure' can be a synonym of 'virgin').
't' put within 'pure' is 'pture'.
'near' with letters rearranged gives 'enra'.
'enra'+'pture'='ENRAPTURE'
(Other definitions for enrapture that I've seen before include "Give intense pleasure to" , "Bewitch" , "Ape Turner (anag.)" , "entrance" , "Give delight to" .)
