St. Marys & Kingsland Railroad The StM&K was incorporated in 1906, and the tracks between its two namesake Camden County towns were completed soon thereafter. In 1911, the line was reorganized as the Atlantic, Waycross & Northern Railroad with plans to build well beyond Kingsland to Fort Valley, some two hundred miles to the northeast. The extension was never constructed. In 1924 the line was reorganized as the St. Marys Railroad.   RailGa.com.
