Reissue shares in existing station (10)

I believe the answer is:

reallocate

'reissue shares' is the definition.
(allocate shares of something again)

'existing station' is the wordplay.
'existing' becomes 'real' (similar in meaning).
'station' becomes 'locate' (to be stationed somewhere is to be located there).
'real'+'locate'='REALLOCATE'

'in' acts as a link.

(Another definition for reallocate that I've seen is " Distribute differently".)

I've seen this clue in The Times.
