Metra’s A-2 Crossing is likely the biggest bottleneck in the Midwest passenger rail network.
A new bridge to allow trains from Union Station to “flyover” trains from Ogilvie Transportation Center is needed.
Located two miles from Union Station at Western Ave. and Kinzie St., A-2 is where Union Pacific-owned tracks from Ogilvie Transportation Center cross Metra-owned tracks from Union Station. It is one of the busiest and most complicated rail intersections in North America with 350 trains crossing paths here every day.
