Origin

UM.73 was a 3-aspect automatic signal commissioned at Swindon MAS Stage 1 on 14 November 1966[1]. At that stage it was supervised by Highworth Junction SB. It was the first colour light stop signal on teh Up Main in the new set of track circuit block sections that had been installed between Highworth Junction and Uffington SBs.

It had its own repeater, UM.73R (which eventually became UM.75 under Swindon MAS Stage 5).
