BN 6923 is mated with a pair of B30-7Bs as they lift an eastbound intermodal train up the grade over the Pine Ridge near Crawford, NE.

Unit built as a Locotrol slave, that and an odd number make it a little interesting.

Four units, four schemes! On Nov. 5, 1999, NS' 11R-H2-03 train, enroute from Binghamton, NY to Linwood, NC, hosted BN SD40-2 6923, ATSF GP60M 139, STLH SD40 5542, and CP SD40 5592.
