Birmingham New Street Signal Box, Birmingham, England
Bicknell & Hamilton and W.R. Healey 1965
“The corrugated concrete Brutalist structure may polarise public opinion, but is actually home of one of the city’s most vital and intense infrastructure systems, serving the busiest rail interchange in the UK.
The technology inside is of the same era as the exterior façade and was revolutionary for its time. The Relay Room sits just above street level and houses enormous banks of algorithmic electronic relays, known as Wespacs, which are programmed to calculate legal routes for the trains to take.
To maintain these systems, Network Rail engineers have to retain specialist knowledge of technology that is decades old. The long aisles of Wespacs are lit by incessantly flashing green and red lights and the extraordinary sound of thousands of relays clicking fills the room.
Love it or hate it, signal boxes are soon to be a thing of the past. Over the next decade the signal boxes of the UK will be consolidated into centralised control centres where a single computer will control vast areas of track, a far cry from the ticking behemoths of the New Street Signal Box.
Thankfully, due its listed status, the humble concrete box on Navigation Street will remain a bastion for the romance of the railways, if only in spirit.”
