Time machine
Why can you never find a policeman when you want one? It was in part to provide a solution to this old question that London’s Metropolitan Police Force began to adopt ‘police boxes’ in the late-1920s. Police boxes contained a public telephone (accessible from outside the box via a small door), as well as a large door to admit a police officer and to give them access to a chair, a small table, writing equipment, an electric heater, and other bits of kit. Such boxes enabled an officer to contact his local police station to summon help. A flashing light on top of the box acted as a signal to a passing officer to contact his local station. These lines of communication were invaluable in the era before personal radios (let along mobile phones), when the only other way an officer could try to get help was to blow a whistle.
The design of the box used in London was the work of Gilbert Mackenzie Trench, surveyor to the Metropolitan force. These chunky boxes, taller and larger than standard telephone boxes and made of concrete with wooden doors,* became quickly familiar, although they were not the first of their kind. The idea of a police box was first taken up in Glasgow, where tall hexagonal boxes, painted red, were used from 1891 onwards. They became ubiquitous on the capital’s streets (and in some towns outside London), until the use of personal radios became the norm in the 1960s and 1970s. The boxes had slipped from my consciousness until the other week, walking around the Borough of Kensington and Chelsea with a friend, I was surprised to find this one outside Earls Court underground station.
Because of the use of such a box as the portal to a time machine in the British TV programme Dr Who, the design is still well known, so I wasn’t entirely amazed that at least the occasional box has been preserved to pay tribute to television history as well as to the history of policing and design. However, the Earl’s Court box is actually a reproduction – according to online sources it dates to 1996. I was nevertheless still pleased to have my memory jogged. Objects that remind us of past times are time machines in their own way, taking us back…but also bringing us forward to a time when communications are easier, when they work.†

* The original design specified a wooden structure with a concrete roof, but concrete walls were adopted for durability.
