I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">complains bitterly</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>

(Other definitions for rails that I've seen before include "secretive birds" , "Makes a protest" , "Wading birds - dysfunctional person has come off them" , "Tracks or barriers" , "Train tracks" .)

I've seen this clue in the Evening Standard.
