Gamst, Frederick C.; The Transfer of Pioneering British Railroad Technology to North America, Central Pacific Railroad Photographic History Museum; "First, in 1795 on Boston's Beacon Hill, a wooden railway of about a two-foot gauge in the form of a double-track inclined plane took earth removed from the top of the hill to its base. This excavation prepared a level area for the new State House of 1798, designed by the architect and construction engineer Charles Bulfinch."
