Station to which a successful man can get a first-class return (8)
I believe the answer is:
victoria
'station' is the definition.
(Victoria is a major railway station in London)
'a successful man can get a first-class return' is the wordplay.
'a successful man can' becomes 'victor' (I can't explain this - if you can you should give a lot more credence to this answer).
'get' is a charade indicator (letters next to each other).
'a first class' becomes 'ai' (Av - top quality).
'return' says the letters should be written backwards.
'ai' reversed gives 'ia'.
'victor'+'ia'='VICTORIA'
'to which' acts as a link.
Can you help me to learn more?
(Other definitions for victoria that I've seen before include "Queen (eighteen thirty seven to nineteen hundred and one)" , "one wasn't amused" , "Queen, Australian state and plum" , "Queenly" , "British queen" .)
