Series 1: Photographs, 1900 - 1975

The Eugene Casey Tunneling Collection comprises an extensive assortment of photographs and slides, publications, clippings, reports, engineering drawings, prints, and personal papers evidencing a comprehensive history of tunneling construction methods in North America and throughout the world. Notable items include hundreds of early subway construction photographs, original reports and documents regarding the construction of the Holland Tunnel, many of them signed by Holland himself, an early photograph of the “10-Car Train No. 3998,” Red Hook Interceptor Tunnel documents, and an original hand-drawn diagram of a “hospital lock.” Also noteworthy are two document boxes containing photographs of the construction of the Hudson & Manhattan Railroad Tube dating from 1912; these are believed to be the only photographs on the subject in existence, given that all other copies are assumed to have been destroyed in the Port Authority Archives at the World Trade Center.
