Of the twenty SDP40s constructed, six belonged to the Great Northern. Burlington Northern SDP40 9850's heritage is obvious, as it has yet to be repainted into BN Cascade Green. The attractive Big Sky Blue, white and gray paint is a giveaway that this engine used to belong to the Great Northern, as their 320.
Not
