Train exiting tunnel on August 1, 1983.  GP9's #1743 and #1713 hold back boxcars loaded with grain on a steep section of track along the line.  This train will drop about 350' in elevation in about 3 miles down to Palisades.  One of my favorite photos taken of this line.  Blair Kooistra photo.  Here is another shot of that train just moments before.

Here is a picture taken from the locomotive's perspective some 26 years later.  September 2009 photo.
