Tay Bridge
On the night of 28 December 1879 at 7.15pm, the bridge collapsed after its central spans gave way during high winter gales. A train with six carriages carrying seventy-five passengers and crew, crossing at the time of the collapse, plunged into the icy waters of the Tay. All seventy-five were lost. The disaster stunned the whole country and sent shock waves through the Victorian engineering community.
