Rayners Lane signal box
Rayners Lane signal box was opened by London Transport in 1935. It was built to the London Transport Type design and was fitted with a 35 lever frame. Three switch panels were fitted, in 1975, in 1985, and the last in 1987. On of these panels, possibly the 1985 one, replaced the frame.
Signalman on duty at Rayner Lane signalbox circa 1980, he controlled
the junction between the Piccadilly and Metropolitan lines by means of a Push-Pull lever
frame.
These red & black route levers controlled both signals and points. The black
point levers to the left of the Signalman (Harry Palmer) had to be centred if the yellow
route control lever was reversed.
