Report of the Hoosac Tunnel and Troy and Greenfield Railroad, by the Joint Standing Committee of 1866.

This 1866 Senate report offers a meticulous look at one of New England’s most ambitious 19th‑century engineering ventures: the Hoosac Tunnel and the Troy‑and‑Greenfield Railroad. A joint standing committee spent months touring the tunnel and its adjoining line, examining construction progress, mechanical operations, and the tangled web of contracts that underpinned the project. Their findings include detailed observations of the tunnel’s structural condition, the nascent railroad service that began in October, and the state’s role in overseeing the work.

Beyond the on‑site inspections, the document traces the railroad’s financial saga from its 1848 charter through a series of under‑performing assessments, costly contractor agreements, and the eventual surrender of the line to the Commonwealth. Readers will encounter excerpts from corporate records, legislative excerpts, and candid commentary on the challenges faced by both the directors and contractors as they struggled to bring the tunnel and rail link to fruition.
