Development, say, around transport hub (9)

Ross

I believe the answer is:

gestation

I'm a little stuck... Click here to teach me more about this clue!

'development' is the definition.
(I've seen this before)

'say around transport hub' is the wordplay.
'say' becomes 'eg'.
'around' is a reversal indicator.
'transport hub' becomes 'station' (I can't justify this - if you can you should give a lot more credence to this answer).
'eg' back-to-front is 'ge'.
'ge'+'station'='GESTATION'

Can you help me to learn more?

(Other definitions for gestation that I've seen before include "Development over time" , "Development (in womb)" , "Development of plan" , "as before being transported by coach" , "Period of development" .)
