It was built to the London Transport Type design and opened in 12th May 1948 fitted with an 83 lever Westinghouse 'N' frame. Two panels were installed on 3rd November 1997, one of which replaced to 'N' frame. The frame remained in situ in 2004 but the plan is to move it to the preserved Epping signal box. the signalbox closed 21st April 2001 when control passed to Wood Lane control room. The frame was removed in May 2005 and moved to Epping.
