Burlington Northern SW10 436 poses with a companion at Sterling, Illinois, on a branch line now abandoned, probably in the summer of 1978. The unit was outshopped by EMD late in 1970, having been ordered as the CB&Q 9323. It became BNSF 3629. The other unit, NW2 566, was delivered in 1949 as CB&Q 9410A; it was retired in 1983.
