A very short Canadian Pacific stack train led by Soo Line GP38-2 #4444, and trailed by Soo caboose #104 passes by Midway Airport (on the other side of the fence to the right) on the Belt Railway of Chicago (BRC). Most likely, this train originated sometime the day before in Canada, has come into Chicago via the CP/Soo main either to the north via Wisconsin, or the west via Minnesota, and has been split up with other containers going to different destinations. The caboose is required by the Belt, on this transfer run into BRC's massive Clearing Yard.
