Redstone granite can be found in many old station buildings of the Boston & Maine Railroad. In its heyday, the quarry at Redstone had more than twenty derricks in operation. Huge slabs of red, pink, or green granite were shipped near and far with the Boston & Maine railroad, whose cars went directly into the quarry for loading. You could say the growth of the quarry matched the growth of the railroad line, as each new train station was built with Redstone granite.
