Climbing the 2.2 percent mountain grade on the Harrison branch, Montana Rail Link No. 403 emits a little smoke with three cars as it approaches milepost 6 north of Harrison, Montana, on May 17, 2013. This 9.5-mile branch serves a lone elevator at Harrison with the local operating here about once a week. The 49-year-old locomotive is used to climbing grades, being former Rio Grande GP35 No. 3039.
