Cheshire railway town (5)
I believe the answer is:
crewe
'cheshire railway town' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for crewe that I've seen before include "Ace wanderer lax (anag)" , "railway junction" , "Cheshire town long associated with railways" , "Cheshire rail junction" , "Famous railway town" .)
