Northern Pacific 0-6-0 class L-7 #1031 was built by Alco in 1903. It is on display outside the Yellowstone County Museum near the entrance to Logan International Airport in Billings, MT.
The museum was founded in 1953 by a group of local individuals and the collection contains over 23,000 artifacts specific to the region, including items from prehistory through the Fur Trade Era and Post Reservation Period. It is displayed in 5,000 square feet of exhibit space in an historic original "log cabin".
A coal burner, #1031 weighs 126,200 lbs with 19” x 26” cylinders and 51” drivers. Operating at a boiler pressure of 180 psi, it delivered 28,200 lbs tractive effort and it is typical of early 20th Century switching locomotives before larger,
0-8-0 switchers began to predominate. Although orders did continue right into the 1940s, 0-6-0s were generally used on lighter duties and in smaller yards.
#1031 was the last steam switcher to operate in Northern Pacific’s Billings, MT, yard. It was retired in 1956 and then donated to the museum.
