Soo Line 2719 is a 4-6-2 "Pacific" type steam locomotive built by the American Locomotive Company (ALCO) for use on passenger trains operated by the Minneapolis, St. Paul and Sault Ste. Marie Railway ("Soo Line"). No. 2719 was used to haul the Soo Line's last steam-powered train, a June 21, 1959 round-trip excursion between Minneapolis, Minnesota and Ladysmith, Wisconsin. It was then displayed in Eau Claire, Wisconsin until 1996.[3] It was restored and operated in excursion service from 1998 until 2013 when its boiler certificate expired. Today, the locomotive remains on static display in Duluth, Minnesota.
