CBRW 166 and 171 pair up at Warden, WA on the Columbia Basin Railway. The 166 was once Duluth, Missabe & Iron Range Phase 4 SD9 166. It was the last Missabe unit in the original color scheme, modified in 1967 with a vertical yellow headlight panel on the noses. Now with a chopped nose and new color scheme, it operates daily on the various branches of this shortline carrier.
