The basement housed the boiler room, a smaller waiting room, kitchen storerooms, and baggage rooms. The station appears to have had two side platforms serving four tracks, accessed through a basement-level tunnel that was reached from the main waiting room by a staircase. The steep roof over the center block had several dormers, some of which were later removed. A covered ramp from the west wing, which had direct access from the south platform, led to a small trolley station on Glenwood Avenue.
