Box clever: the surprising history of signal boxes

Petersfield signal box is in the wrong place. Or at least it is now. When it was built in the 1880s, it was in precisely the right place, near the tracks and next to the level crossing that the signalman controlled. It had to be. Signal boxes had a series of big levers which controlled both signals and the points on the track. In the days before electric motors, the boxes had to be as near as possible to the points or shifting the levers became too difficult, especially in cold weather.

Petersfield is Grade II listed because it is a rare example of a box containing equipment developed by the London & South Western Railway, which built most of the lines out of Waterloo. It now faces demolition as Network Rail is decommissioning the box and wants to improve the level crossing next to it.
