Alterations in connection with Reversible Signalling
From 19 June 1977 the signal was mounted on a right-hand cantilever, in readiness for the future installation of SN.693R on the same structure.
The reversible signalling was brought into use in 1981 [4].
Aspect Sequence
YY aspect introduced on 13 Sep 1993 does not seem to have been brought into use on that date: "When SN.89 is displaying a green aspect, SN.93 may be displaying a yellow or green aspect" [1]. At what date was the YY brought into use, if ever?
