BNSF SD40-2 7865

Last train of the day before the clouds opened up and the rain came pouring down, and my luck held. It looked like just another set of BNSF Cascade Green SD40-2s, but the trailing unit of the three had a tiny "C&S" stenciled on the side, indicating this one had once been assigned to BN subsidiary Colorado & Southern. Not many of these C&S sub-lettered units still running around out there.
