Severn Bridge Junction signal box in Shrewsbury is Grade II listed and the largest mechanical signal box in the world that is still operational, has just received its biggest refurbishment in more than a decade.

The 117-year-old signal box retains its original 180 levers, with 89 of them still in use today, and is responsible for signalling around 280 trains every day.
