Hi,
Every time I pass through Smethwick Galton Bridge (Lower Level) I often wonder something, but I'm too slow on the uptake to get my camera out. There are a number of cabinets with what looks like a speaker or horn on top of them.
Why would a cabinet need a horn? I've never heard them sounding when I've gone past on a train with an open window.
Thanks,
