Conversion to Controlled
This signal was planned to be converted to a controlled signal (SN.18) (from a semi-automatic) on 2 August 1970:
But the work did not take place as planned:
and the signal was actually converted to SN.18 on 6 September of that year.
Conversion to Automatic
Latterly the signal was converted back to an automatic.
Upgrading to 4-aspect
The signal was re-fitted with a 4-aspect head at 04.50 on Monday 28 January 2002, although the top yellow was not brought into use.
