A westbound grain train is on a eight mile stretch of single track between Berea and Hemingford. A manifest is waiting on Main 2 at Hemingford, about a mile ahead, for the grain train. Two coal loads are stacked up behind the manifest, too.
The lead unit here, BNSF 4252, is a Tier 4 "credit unit". BNSF had some emissions credits saved up that allowed them to purchase some Tier 3 units even after the Tier 4 deadline.
