It's all NS at Toluca, Illinois on the former ATSF transcon. Here we view a BNSF westbound stack train passing NS' Kansas City train just out of the connection at Streator.
IAIS #513 rolls near Adams Street with a detouring "BICB" train headed for BNSF's Peoria Sub. The train will use the route to get to Galesburg, then ride the Barstow Sub home to Colona, IL.
