Remarkable fight that's seen from passing train? (6,3)

Ross

I believe the answer is:

signal box

'that's seen from passing train?' is the definition.
(by a railway track)

'remarkable fight' is the wordplay.
'remarkable' becomes 'signal' (signal can mean striking or noteworthy).
'fight' becomes 'box' (boxing is a kind of fighting).
'signal'+'box'='SIGNAL-BOX'

(Other definitions for signal box that I've seen before include "Building beside a railway track" , "Goblin sax (anag.)" , "Train-control hut" , "Cabin where rail movements are controlled" , "Control point on railway" .)

I've seen this clue in The Guardian.
