The sudden collapse of Scotland's Tay Bridge in 1879 killed more than 70 rail passengers and shocked the population. An extensive inquiry was carried out, including numerous witnesses, experts and reports. Were the high winds that night to blame, or were poor design or mechanical failure at fault? This free course re-examines some of the original evidence from the Tay Bridge disaster.
