Union Station towers

Did anyone catch this week's Crain's? It had a great article in a commercial real estate section about failed projects in the city (Loop circulator, Helmut Jahn's plans for Navy Pier, etc.). Nice group of pix. Anyway, one of the failed projects mentioned was that plan to add to neoclassical towers atop Union Station. Before reading Crain's, I thought the idea was still alive. Does anyone know anything about its status. I remember the plans were pretty cool, including extending the atrium in the station's main waiting room.>
