The Bridge Fell in a Storm. The Train Was Still Inside It

Sunday 28 December 1879: a gale, a train, and the longest bridge in the world. By morning the middle of the Tay Bridge was gone, and the train was in the river. How a bridge built on a budget, passed in calm weather and patched with wax became one of Britain's worst railway disasters. In 1878 Thomas Bouch's Tay Rail Bridge opened at Dundee, nearly two miles of iron lattice girders on slim cast-iron piers. Queen Victoria crossed it in 1879 and knighted its designer. Nineteen months after opening, during a violent storm on the night of 28 December 1879, the thirteen "high girders" fell into the Firth of Tay with a North British Railway train inside them. There were no survivors. The court of inquiry counted 75 people on board (modern research has named 59; 46 bodies were recovered). The inquiry found weak cross-bracing on narrow piers, badly cast iron lugs, loose ties that the inspector had re-wedged, cast columns with defects filled with "Beaumont egg", trains running well over the 25 mph limit, and no specific allowance for wind loading. Its chairman, Henry Rothery, concluded the bridge was "badly designed, badly constructed and badly maintained". Bouch's Forth Bridge design was abandoned, he died in 1880, British bridges were required to allow for wind pressure of 56 lb per square foot, and a new double-track Tay Bridge opened beside the old piers in 1887.
