Passing through another station (8)

I believe the answer is:

relaying

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

'passing' is the definition.
(relaying is a kind of passing)

'another station' is the wordplay.
'another' becomes 're' (I've seen this in other clues).
'station' becomes 'laying' (I can't justify this - if you can you should believe this answer much more).
're'+'laying'='RELAYING'

'through' is the link.

Can you help me to learn more?

(Other definitions for relaying that I've seen before include "Broadcasting" , "Communicating" .)

I've seen this clue in The Globe and Mail.
