Long-Bell Lumber No. 1000 and 1001

United States 1924 2 produced
No. 1001 in 1952 at Tennant, California Taylor Rush/Max Miller collection

Baldwin works numbers 57597 and 57598 were built in 1924 for the Long-Bell Lumber Company. The requirements included that they had to run through 40-degree curves, what meant a radius of 44.5 meters, while being able to haul heavy lumber trains up grades of six to seven percent. The solution was a 2-6-6-2 Mallet that was called Baldwin type 16 30/50 1/4 DD. They had cylinders with diameters of 18 and 28 inches and a stroke of 24 inches. The drivers measured only 44 inches for maximum tractive effort.

The locomotives were numbered 1000 and 1001 and coupled to tenders with 1,500 gallons of oil and 5,000 gallons of water. In the first two decades, they hauled the fir wood from the Long-Bell properties around Longview, Washington. In 1946, at least No. 1001 was transferred to Northern California and hauled pine wood around Tennant. What is sure is that both were scrapped in the mid-fifties. Today the bell of 1001 can sill be found in the fire hall in Tennant.
