Northern Pacific 328 is a preserved S-10 class (NP S-10)^[1] 4-6-0 "Ten Wheeler" type steam locomotive, built in August 1905 by ALCO's Roger Works, the locomotive hauled passenger trains along the NP system until it was sidelined in August 1950. After being on display in Stillwater, Minnesota's city park, it was restored to operational condition in 1981, and was retired again in 1999. As of 2026, the locomotive is on static display at the Minnesota Transportation Museum's Jackson street Roundhouse.

History

Revenue service

No. 328 was built in August 1905 by the American Locomotive Company at their Rogers plant in Patterson, New Jersey. It was originally designed for fast passenger service.^[2] In 1940, it was named Blueberry Special, after the train that ran between Rush City, Minnesota and Grantsburg, Wisconsin. No. 328 pulled the last train to Taylors Falls on June 30, 1948. In 1949, L-10 0-6-0 No. 1167 replaced 328 on the Grantsburg branch.^[2]

First retirement

In August 1950, No. 328 was retired and was sold to the Minnesota Railfans Association. It was displayed at the city park in Stillwater, Minnesota, for 26 years.^[3]^[4]^[2]

Excursion service

In 1976, it was leased by the Minnesota Transportation Museum for an operational restoration.^[2] The engine returned to service in May 1981, and ran excursion trips during the 1980s.^[2] Between 1987 and 1991, No. 328 returned to the Stillwater Branch and was owned by the Minnesota Transportation Museum and was a “crown jewel” of the historic experience.^[5] In 1992 NP served as a regular locomotive on MTM's Osceola & St. Croix, MN and Dresser, WI.^[6]^[7]^[2] In 1998, No. 328 had its most famous trip when it participated in a triple header with Soo Line 1003 and Soo Line 2719 at SteamFest '98 from Wisconsin to Minnesota.^[8] In 1999, it traveled a few more miles from the Stillwater and Taylors Falls branches it once frequented and made occasional special trips around the Twin Cities.^[2]

Second retirement

In 1999, No. 328 was retired from service once again and today it is an exhibit at the Jackson Street Roundhouse.^[2] There are unknown plans to restore No. 328 back to operation.^[9]^[10]^[11]^[12]
