After meeting one at Woodford, BNSF6606 tries to get back going on the grade... Run 6, sanders on, and he couldn't pull it, just kept rolling backwards. I guess BNSF will learn the hard way you can't have 4 B-B's on a 8000 ton manifest and try to climb that grade from a dead stop. Was pretty interesting and a sight to see for sure watching him roll back about a full car length.
