 The station's control house, a grand, ornate entrance to what was then the terminal of the Interborough Rapid Transit Company's Brooklyn lines, was designed by Heins & LaFarge, who also built the Cathedral of St. John the Divine in Morningside Heights, Manhattan.This control house was listed on the National Register of Historic Places in 1980; however, the actual entrance is now removed and now serves as a skylight into the IRT station.During the 1964–1965 fiscal year, the Brighton Line platforms at Atlantic Avenue, along with those at six other stations on the Brighton Line, were lengthened to 615 feet to accommodate a ten-car train of 60-foot IND cars, or a nine-car train of 67-foot BMT cars.
