A Baltimore & Ohio transfer run is seen here passing Chicago's Western Avenue station. The tracks in the foreground belong to the Milwaukee Road, with those immediately this side of the freight belonging to the Chicago & North Western; the two roads cross just out of the picture to the left with the Milwaukee heading into Union Station and the C&NW into Madison Street Station. The B&O run is on Pennsylvania rails, which join the Milwaukee on the other side of the crossing to enter Union Station. The crossing tower is visible at center left.
