The frame is a Westinghouse Style 'L' Power Frame which is all electrically locked. The frame was formed of 2 x 12 way and 1 x 8 way section which making a total of 31 levers, {2x12}+8}-1 = 31 levers, as the last “lever” space is unavailable. 6 of these levers worked the points, 15 signal levers operated the coloured light signals, and 3 spare levers when the frame was installed. This made the working lever total of 29. pictures above and below by kind permission of © Graham Floyd.

Two very interesting pictures during the installation of the lever frame into its new signal box, the 31 vertical 'D' band electrical contacts can be seen at the front, whilst above these the on top of these can be seen the initial batch of levers and their electric locks have been installed. The bottom picture shows all the white electrical wiring necessary to work the electric interlocks between the levers, as well as the signals and point circuits.
