On the third and most top floor of the King Memorial station, is the Marta railway line itself. The King Memorial station railway is on the Marta blue line and is between Georgia state and Inman Park/Reynoldstown station. The railway stop stretches about 500 feet long across the railway. The railway stop is very atmospheric because of how wide and open to space it is. Huge openings on the side and ceilings provide the station with plenty of natural light. The entire ceiling is designed with metal bars interconnected in a triangular pattern providing a place were lights can be installed and a cool architectural feature.
