BNSF 5973 East from Mississippi Palidades State Park on 7-2-09 HD

Taken from the overlook view on the east side of the Mississippi River in Mississippi Palisades State Park. Savanna, Illinois. Trains; boat, barge and river boat traffic; soaring birds and the river vista can be seen from this lofty perch. Does anyone have a thought on what this train was carrying? Cars were less than half full and the material was greyish in color. The train went south on the Barstow sub. Photo at: http://www.flickr.com/photos/basicbill/3682585307/ Please watch in HD.
