When Broadway Station was initially opened a small wooden signal box with 13 levers was constructed at the end of the up platform. This was replaced by a 37 lever wooden signal box on the down side, just to the south of the road bridge. It was intended that the signal box be rebuilt in its original location. The original design was of wood on very deep concrete foundations, due to the nature of the made up ground. However current operating practices and a desire for the railway enthusiasts to be in close proximity to the signalling action and have a close view of the new Signal Box, it was decided to build it on the southern end of the up platform.
The construction of the Signal Box is complete and it bears close resemblance to to the Shirely Box (above left). Work on installation of the locking mechanism is in progress.
