The helper units are being uncoupled from the grain train. To the left the east portal of the summit tunnel is evident. Most of the train is inside the tunnel, although the head end power and about a dozen cars are on the sunny side of the west portal.

The uncoupling completed, the engineer inches his units away from the grain train. In the upper left the guard railings of I-90 are visible.
