Tay Bridge disaster Scottish author A. J. Cronin, includes a scene involving the Tay Bridge disaster, and the 1942 filmed version of the book dramatically recreates the bridge's catastrophic collapse. The bridge collapse also figures prominently in Barbara Vine's 2002 novel "The Blood Doctor". Tay Bridge disaster During a violent storm on Sunday 28 December 1879, the first Tay Rail Bridge collapsed as a train from Wormit to Dundee passed over it, killing all aboard. The bridge—designed by Sir Thomas Bouch—used lattice girders supported by iron piers, with cast iron columns and wrought iron cross-bracing. The piers were narrower and their cross-bracing was
Tay Bridge disaster were now constructed by sinking brick-lined wrought-iron caissons onto the riverbed, and filling these with concrete. To reduce the weight these had to support, Bouch used open-lattice iron skeleton piers: each pier had multiple cast-iron columns taking the weight of the bridging girders. Wrought iron horizontal braces and diagonal tiebars linked the columns in each pier to provide rigidity and stability. The basic concept was well known, but for the Tay Bridge, the pier dimensions were constrained by the caisson. For the higher portion of the bridge, there were 13 girder spans. In order to accommodate thermal expansion, at only
