The community was named for Colonel James Alexander Boyd (1823–1896), a Scottish immigrant who was a construction engineer for the Baltimore and Ohio Railroad. Boyd built a temporary village to house construction workers as the Baltimore and Ohio Railroad built the Metropolitan Branch line after the American Civil War. The railroad line began service in 1873. After the railroad station opened, a mill, stores, and other businesses were established in the area. The Baltimore and Ohio Railroad opened a brick railroad station in 1887. The railroad station was demolished to make way for installation of a second track in 1927. A wooden station was built as a replacement, but it was later taken down.
