The Ashtabula River railroad disaster (also called the Ashtabula horror, the Ashtabula Bridge disaster, and the Ashtabula train disaster) was the failure of a bridge over the Ashtabula River near the town of Ashtabula, Ohio, in the United States on December 29, 1876. A Lake Shore and Michigan Southern Railway train, the Pacific Express, passed over the bridge as it failed. All but the lead locomotive plunged into the river. The train's oil lanterns and coal-fired heating stoves set the wooden cars alight. Firefighters declined to extinguish the flames, leaving individuals to try to pull survivors from the wreck. Many who survived the crash burned to death in the wreckage. The accident killed approximately 92 of the 160 people aboard. It was the worst rail accident in the U.S. in the 19th century and the worst rail accident in U.S. history until the Great Train Wreck of 1918. The coroner's report found that the bridge, located about from the railway station, had been improperly designed by the railroad company president, poorly constructed, and inadequately inspected. As a result of the accident, a hospital was built in the town and a federal system set up to formally investigate fatal railroad accidents. Design and construction of the bridge In 1863, officials of the Cleveland, Painesville and Ashtabula Railroad (CP&A; one of the predecessors of the Lake Shore and Michigan Southern Railway), decided to replace the wooden bridge over the Ashtabula River just east of the village of Ashtabula, Ohio, with an iron structure. Amasa Stone was president of the CP&A. His construction firm had built the CP&A main line from 1850 to 1852, and Stone had purchased the patent rights to brother-in-law William Howe truss bridge in 1842. Stone resolved to construct a Howe truss bridge, a commonly used type of railroad bridge, and personally designed the new bridge. The longest span was long and above the river below. Stone also decided to award the contract for the ironwork to the Cleveland Rolling Mill (then known as Stone, Chisholm & Jones Company), an iron and steel company based in Cleveland, Ohio, which was managed by his older brother, Andros Stone. The I-beams were made by the mill. The mill also provided raw iron to the CP&A, which then made the cast and wrought iron elements according to the fabrication plans. Shop master mechanic Albert Congdon oversaw this latter work. Design Amasa Stone's
