I believe the answer is:

entrance

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

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

I don't understand the remainder of the clue.

(Other definitions for entrance that I've seen before include "Way in - fascinate" , "Ingress" , "Hold" , "Gate" , "it's common, say, for some children to sit" .)

I've seen this clue in The Times.
