Wymondham South Junction Signal Box

Wymondham South Junction Signal Box is a signal box built for the Great Eastern Railway in 1877. It features a timber construction with a slate roof covering. The signal box is located a short distance to the west of the station, at a point where the railway tracks fork into two, and has a rectangular plan.

The exterior of the signal box includes a pitched roof with exposed rafters at the eaves and plain bargeboards. It sits on a brick plinth and is clad in horizontal timber painted in green and pale yellow, reflecting the colours of the Great Eastern Railway. The locking room on the north side is illuminated by a group of three horizontal, four-light windows with vertical glazing bars and is accessed from the west via the original timber door. The upper operating room is lit on all four sides by original large sliding windows with vertical timber glazing bars, featuring five four-light windows on the north and south sides, three three-light windows on the east side, and two three-light windows on the west side. Access to this room is through a timber door with a glazed upper panel, which is not original.

Inside, the signal box retains the McKenzie and Holland 42 lever frame, the date of which is unknown, and secondary glazing has been fitted.
