Granite Railway begins operating in Quincy.

Architect: Gridley Bryant. Built by a company led by Amos Lawrence, T.H. Perkins, and others, the three-mile line runs from the Quincy quarries to docks on the Neponset River. Incorporated on March 4, 1826, it is the first commercial railroad in the U.S. and is used by for oxen-drawn cars that carry granite blocks, initially for construction of the Bunker Hill Monument and subsequently for building the Custom House, Old City Hall, Suffolk County Court House, and dry docks at the Charlestown Navy Yard. The line is taken over by the Old Colony Railroad in 1871, then by the New York, New Haven & Hartford Railroad in 1893. The first steam engine is used on the line in 1899.
