I'm afraid I can't even guess how this answer relates to the clue.

(Other definitions for rails that I've seen before include "Metal bars of a barrier" , "Barriers of horizontal bars and supports" , "Wading birds - dysfunctional person has come off them" , "For trains" , "Makes a protest" .)

I've seen this clue in The Irish Independent.
