Follow railway (5)

I believe the answer is:

track

I believe this is a double definition.

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

'railway' is the second definition.
(thesaurus)

(Other definitions for track that I've seen before include "Single item on a CD" , "Pathway" , "Shadow" , "racecourse" , "Rough path or road" .)

I've seen this clue in The Mirror.
