Park Junction Box 1956
Owen writes 'The largest signal Box on the Northern Line.But due to the last war, the 1938 plans to electrify from Finsbury Park to Alexander Palace plus the Mill Hill Edgware link not to mention the expansion of Highgate woods sidings that were never track circuited. You note from the diagram that they have been covered with paper. The Alexandra Palace branch is shown. Now there were more spare levers than those in use.

Records show that the 83 lever frame had a number of spare levers, the working one's were 45 points, 23 signals and 10 route levers and 3 calling on arms.
How time changes everything! Nick Catford took this picture is August 1990, some 6 years after closure, the box has been vandalised, the weather has got in and rusted all the chrome lever handles, and everything looks in a really sorry state. i guess it all got demolished and all went for scrap, which is a shame really considering how much it originally cost.
