The Taylor-Wharton Iron & Steel Company produced frogs, switches and other railroad fittings including couplings, axles and wheels, as well as war material during both World Wars. The company was incorporated in 1912 as successor to the Taylor Iron & Steel Company. The collection contains photographs primarily of products such as dredging equipment, railroad tracks, rollers, crushers, and buckets. The films document dredge buckets in operation and were shot in the United States and at international locations. The collection has been organized into four series: Company history, Plant views, Products, and Films. Each series is arranged alphabetically.
