The power signal box on the edge of Birmingham New Street station has finally come to the end of its working life. Last Christmas, 57 years after being commissioned as part of the radical overhaul of the city’s main interchange, the signallers pulled off the final levers and dispatched the last of more than 1000 daily trains that are routed by the centre. The PSB, which is an architecturally significant building, has now been decommissioned, but its future has yet to be decided, given its valuable city centre location – not to mention unrivalled views of operations at the busy station.
