Track English whisky (3)
I believe the answer is:
rye
'whisky' is the definition.
(rye is a kind of whisky)
'track english' is the wordplay.
'track' becomes 'RY' (abbreviation for railway).
'english' becomes 'e' (abbreviation).
'ry'+'e'='RYE'
(Other definitions for rye that I've seen before include "Grain - whiskey - port" , "New York bread" , "American whisky" , "Grain used in flour and whiskey" , "Burns's body came through" .)
