Book excerpt: On June 27, 1835, New Hampshire chartered the Boston & Maine Railroad, and a juggernaut was born. By 1900, the B&M operated some 2,300 miles of track in northern New England, having taken over an astonishing forty-seven different railroads since its inception. The B&M loomed particularly large in the Granite State, where it controlled 96 percent of all tracks and was the primary conveyance through the rugged heart of New England s most formidable mountain range.From the gravity-defying Mount Washington Cog Railway to logging transport trains to the famous Depression-era Snow Train, A History of the Boston & Maine Railroad traces the fascinating history of New England's most renowned railway.
