Underground railway (5)

Ross

I believe the answer is:

metro

'underground railway' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for metro that I've seen before include "Parisian rail system" , "The Paris Underground transport system" , "Parisian underground railway" , "Paris underground rail system" , "Paris subway" .)

I've seen this clue in The Times and the Sydney Morning Herald.
