There's a new railcam at my old stomping grounds in Chicago. It's mounted on the former powerhouse stack overlooking the throat of the former Northwestern Station (now the Ogilvie Transportation Center). We're looking north in this screen capture. The trains seen closest are inbound and will soon arrive at the terminal. The former MILW line to Union Station is at street level where the crossing is located and you'll see plenty of trains there too, including Amtrak. Union Station is out of view to the right, behind the camera. Obviously, rush hour is prime time on both lines.
