Today, CSX celebrates William Hunter Dammond, a trailblazer in #railroad signaling whose innovations laid the foundation for the systems we rely on today. From his 1903 patent of the electrical track circuit to the development of #safe systems operations (green, yellow, red signals), his work helped revolutionize rail safety and efficiency. Thank you, Mr. Dammond, for shaping the DNA of modern railroading! #BlackHistoryMonth
