The original side platforms were replaced with high-level island platforms, long enough to permit level boarding for twelve-car trains. The platforms and platform supports were constructed of cast-in-place concrete. The line was widened to eight tracks through the station, with the platforms between the 2nd and 3rd tracks and the 6th and 7th tracks. The center non-platform tracks were reserved for through freights, with the outside non-platform tracks used by local freights. Each platform had a -wide waiting room, long on the eastbound (south) platform and long on the westbound platform. The waiting rooms were covered in copper sheathing and had large skylights. The railroad constructed full-length steel platform canopies in their own shops. A separate baggage tunnel, west of the main passenger tunnel, connected with freight elevators to the platforms. When the renovations were complete in 1915, the station was renamed as North Philadelphia.
