On May 10 of 1899, Washburn selected a town site with four blocks in Burleigh County and eleven in McLean County. He named it Wilton; for a town in his home state of Maine. On October 18th the plat for the town was filed.
Washburn realized that if he wanted to populate the area and develop the coal mines, it would be beneficial to have a railroad cross his land. Therefore, he began immediately to organize the Bismarck, Washburn and Ft. Buford Railroad Co. (later the Bismarck, Washburn and Great Falls Railroad Co.) which was completed in 1900. The coming of rails meant Wilton was no longer isolated..
The new railroad bought one "Mikado" type locomotive from the Baldwin Locomotive Works and it was delivered in 1901. The locomotive carried road number 3 and it had 50" diameter drivers, 14" high pressure and 24" low pressure cylinders and with a 200 psi boiler pressure it exerted 28,560 pounds of tractive effort. The locomotive weighed 165,400 pounds and the tender capacity was 5,000 gallons of water and 6 tons of coal.
There are no surviving BW&GF 2-8-2 "Mikado" type locomotives.
|Qty||Road Numbers||Year Built||Builder||Notes|
|1||3||1901||Baldwin||Number 3 was a Vauclain Compound locomotive and became number 1000 after the MStP&SSM purchased the BW&GF in 1904.|
Locobase 9390 briefly describes the BW&GF, a North Dakota road that was absorbed by the Minneapolis, St Paul & Sault Ste Marie in 1904, only a few years after its opening. As part of the dowry, this small, very low-drivered Mikado gave up its number 3 in favor of the round 1000.
Delivered with 14" HP and 24" LP cylinders, each set of two fed by an 11 1/2" (292 mm) piston valve. 1000 was later modified to a simple-expansion layout with a small cylinder volume (See Locobase 9391) . According to the Baldwin history, the requirement covered a powerful locomotive with a wide firebox of large capacity and ample grate area for burning inferior coal or lignite. The specs called for the 3 to be "guaranteed to make sufficient steam for its [unclear] operation."
Some years after the Soo took over the Bismarck, Washburn & Great Falls, it converted its compound Mikado (Locobase 10762) into a simple-expansion engine. In the process, the engine was fitted with an entirely new boiler and firebox; the boiler was larger, the firebox smaller. After its conversion and unlike its Pacific stablemate, the Mike had 12" (305 mm) piston valves operated by outside radial gear.
1000 was dismissed from service" in August 1933.
Data from website sponsoring restoration of 1003. (www.geocities.com/~ronkoholin/soo/soo-006.htm). Superheater size was not stated separately, but the Soo Misc Steam Locomotive Diagrams supplied in May 2005 by Allen Stanley filled in the missing information.
Superheater area is estimated based on the following logic: The diagram gives the "superheater equivalent" area as 1,246.02 sq ft. If that figure is plugged into the specs as given, the superheater ratio is 24%, a pretty high value for this vintage. But if this figure is a result of taking each actual square foot of superheater as equivalent to 1 1/2 sq ft of heating surface, a frequent calculation for the time and the standard figure used by Railway Age, then the result of cutting a third of this number gives the value showing in the specs.
