==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.610]] on the same structure.

The reversible signalling was brought into use in 1981 <ref>Signalling Notice [[31/W/2769]]</ref>.

==Alteration==

The signal was shown as having its number 1 junction indicator and draw-ahead removed in September 1996:
