On the 9th of August, 1867 sudden subsidence at Brandy Hole Viaduct caused a train to derail.
The location of the disaster was Bray Head, County Wicklow, Ireland. Four people died and twenty-five were injured.
The report into the disaster was published a few weeks later, and can be found in full HERE.
“The train to which this accident happened was the up train leaving Enniscorthy for Dublin, at 6.30 a.m. It consisted of an engine and tender, six carriages, of which the first was fitted with a break, and a guard’s break van. A porter acting as guard rode in this van at the rear of the train. It left Delgany about its proper time, 9.5 a.m., and was travelling slowly round Bray Head in obedience to orders which had been given to all drivers, and had nearly reached this wooden viaduct (called Brabazon corner in the details supplied by the engineer (the late Mr. Brunel), previous to the opening of the line in October 1855), when the acting guard says he got a knock in his van, looked out of the window, and saw the carriages hopping on the rails, and then he put on his break.”
