Following the assimilation of the Frisco into the Burlington Northern, BN began renumbering locomotives, cabooses, and some other rolling stock and covering SL-SF markings with “BN.” Repainting into BN colors would come in time for most of the equipment.

BN patched images are presented on the Frisco Archive for historical reference only. Although these images were taken following the demise of the Frisco, the images remain of value due to still being in Frisco colors.
