Underground Signal Box
An S-Stock unit approaches Liverpool Street with a H&C service to Barking.
The signal box was built in 1875 and was in use until 1956, when control moved to Farringdon. It originally had a 40-lever frame, but in 1902 a second mechanical 20-lever frame was installed. In 1954, they were replaced by a 15-lever Westinghouse miniature power lever frame. It was subsequently converted to an interlocking machine room, which is still in use today. The structure was given Grade II listing in 2013.
