Tay Bridge Collapses in Storm: 75 Die on Train

Seventy-five people died on December 28, 1879, when the central section of the Tay Rail Bridge in Dundee, Scotland, collapsed during a violent storm, plunging a six-car passenger train into the icy waters of the Firth of Tay. The disaster destroyed public faith in the Victorian engineering establishment and exposed a pattern of cost-cutting, design failures, and inadequate inspection that had been hidden beneath the reputation of the bridge designer, Sir Thomas Bouch. The Tay Bridge had been the longest bridge in the world when it opened in May 1878, stretching nearly two miles across the estuary. Queen Victoria had crossed it personally and knighted Bouch for his achievement. The bridge consisted of 85 spans, with the central thirteen spans raised to a height of 88 feet to allow tall-masted ships to pass beneath. These "high girders" were supported by cast-iron columns braced with wrought-iron tie bars, a design that provided almost no resistance to lateral wind forces. On the evening of the disaster, the 5:27 PM mail train from Edinburgh entered the bridge during a storm generating winds estimated at 70 to 80 miles per hour. Witnesses on shore saw sparks as the train entered the high girder section, then watched the lights of the carriages disappear. All thirteen high spans had collapsed into the Tay, taking the train and every passenger with it. There were no survivors. Bodies continued to wash ashore for months; some were never recovered. The Court of Inquiry blamed Bouch directly, finding that the bridge was "badly designed, badly constructed, and badly maintained." The cast-iron columns contained hidden blowholes filled with putty and painted over during construction. The cross-bracing was inadequate for routine wind loads. Bouch, who had been designing the Forth Bridge, was stripped of the commission and died within a year. The replacement Tay Bridge, completed in 1887, still stands, with Bouch original pier stumps visible alongside it at low tide.
