Here is an aerial view of the railway tracks and platforms at Union Station in Toronto, Canada. The slide image was taken from the CN Tower, looking down at the station's extensive rail yard and train sheds. At the time, the area was dominated by a vast network of tracks and the Canadian National (CN) yards. 

The large, white-roofed structure in the center is the station's train shed, which covers the platforms.

The image captures the extensive rail infrastructure that once characterized the Toronto waterfront before significant urban redevelopment transformed the area.
