Etymology
From over- + track.
Meanings
-
(not-comparable) Over and above a railway track.
Relics of the old GWR broad gauge are rare on the national network. This overtrack canopy was one such, so the decision by the C&WR to retrieve it after electrification necessitated its demolition was a brave one, because its condition by then was parlous.
