Back to Control Functions
Origin
The signal was formerly a limit of shunt (DM.LOS (Highworth Junction)), but was re-numbered on 6 Feb 1977 to SN.277 as part of the preparatory works for reversible signalling. The signal was initially still fixed at danger but was ultimately to become a pre-set LOS.
