Elephant & Castle was opened by the Baker Street & Waterloo Railway on 19 March 1906 fitted with a 15 lever 'B' Style frame (frame number 49). the box was closed on 01 November 1941.

Elephant & Castle signal box was located in the station building. It was opened by London Transport in 1941 fitted with an 11 lever Westinghouse 'N' frame (frame number 192) which was out of use from 10th August 1991 until the box was closed on 08th September 1991. This N frame was unusual as it was a Push Pull lever frame with nomal in the mid position

Tthe Elephant & Castle lever frame is now located in the LT Depot Museum at Acton

The levers for the points were not in the frame at all, the normal or reverse indications were on the track diagram. In fact, there were no remote interlockings as far Steve is aware at Elephant & Castle.
Lever 1, the southbound home, was what was called a free lever, effectively the lever worked automatically when
reversed.
Lever 2 was a blank space.
Lever 3, when you saw it at the museum and indeed when I saw it in operation at E&C was spare (white) but had been a calling on signal located below signal 10.
Lever 4 was a shunt sounthbound from the northbound running road to the southbound (push) or northbound
(pull) platforms located to the north of the sissors crossing.
Lever 5 (push) was the shunt from the southbound platform to the southbound siding.
Lever 6 was the shunt from the northbound platform to either the southbound siding (push) or the northbound siding (pull).
Lever 7 was the southbound siding exit shunt signal to the southbound plantform (push) or the northbound platform (pull).
Lever 8 was the shunt from the northbound siding (pull) to the northbound platform.
Lever 9 was a blank space.
Lever 10 was the southbound inner home to the southbound platform (push) or the northbound platform (pull).
Lever 11 was the soundbound platform starter (push) and the northbound platform starter (pull).
Crossovers were numbered 101, 102 and 103.
