Tay Bridge openedIn 1878, the original Tay Bridge was officially opened by Queen Victoria. It carried a single rail line across the Forth of Tay on the east coast of Scotland. At almost 2 miles in overall length, it was for its time the world's longest bridge. The engineer was Thomas Bouch, who supervised construction, and was knighted for his work. Sadly, the structure was inadequate in both design and quality to withstand gale force winds, and on 28 Dec 1879, its cast iron piers collapsed as a train crossed the high navigation spans. The engine and carriages fell into the water taking over 75 passengers to their deaths. An official inquiry found Bouch at fault, and that poor maintenance procedures weakened the piers and contributed to the failure.«[Image: collapsed span in water beside broken columns after the collapse of the Tay Bridge.]
