Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 39, p. 74 . See also Bruce Oldenberg, "Baldwin 2-6-2 Tank Logging Locomotives", posted on the Web at [] in 2012 (still active 6 May 2022). Works number was 37661 in April 1912.
FLC's scene of operations near Park Falls, Wisconsin (about 60 miles south of the Lake Superior shoreline) imposed some stiff demands on a small saddle tank. Rolling on 65-lb/yard (32.5-kg/metre) rail, the 2 would face 6% grades and 30-degree curves. And, said the specs, "All parts to be as well above the track as the design will permit ...Track is rough, make all parts, particularly bumper, strong."
Bruce Oldenberg pointed to an additional and unusual limitation. The #2's profile needed to fit under the same bridge as earlier, and presumably smaller, Shay geared locomotives. So "NOTHING [Oldenberg's caps] was higher than the top of the water tank." Oldenberg speculated on the impact of this restriction: "I never learned if it was a poor steamer because such a low steam dome (it's got be there somewhere) and the short stack."
He added that sometime after 1924, the railroad raised the bridge and the #2 now sported a cab with "a more normal height." Wondering if the low cab was a "head knocker", he felt on firmer ground when he wrote "the extra height [of the upgraded cab] might have at least cooled the cab in the summer."
Performance guarantees reflected the arduous service. The locomotive was to be able to haul 76 tons up the straight 6% grade, 126 tons up a straight 4%, and 230 tons up a line that had both a 1 1/2% grade and 26-degree curves.
The 2 served FLC for 35 years before being scrapped in 1947. Flambeau Paper remained in business until it declared bankruptcy and closed in 2006. Investor Butch Johnson bought the plant and reopened it, seeking profitability by converting to non-fossil-fuel and environmentally friendly operation.
