I have been comparing locomotives related to the Flambeau Paper No. 2.
The ones I show on this page are 2-6-2 T, and have the same wheel diameters and wheel bases.
The California Western Railway and Navigation no. 7 and the Flambeau Paper 2 actually have a lot in common.
But the Flambeau was built to fit under a bridge, or to be no higher than the Shay logging locomotive that it replaced.
So the steam dome and all other accessories were no higher than the water tank.
The builder's photo makes it look like a big powerful locomotive, but it is misleading because the cab was very small.
Sometime after 1924, the low clearance situation was changed,
and the cab roof of No. 2 was raised to a more normal height, see my drawing on the right of the 3 above.
The stack was extended to a normal height, and the bell and lights were moved higher.
I don't know how bad a 'head knocker' the original cab was, but the extra height might have at least cooled the cab in the summer.
There's 17 years difference in design between the California and Western (built 1909),
and the current Black Hills Central 104, (built 1926).
But they all have the same diameter wheels and the same wheel base.
The C. W. has slide valves, and the Black Hills Central has piston valves.
My crude measurements say the BHC stands 4 inches taller. Maybe the frame was stronger or higher, or maybe had a taller stack of springs?
The Black Hills Central is relatively wide compared to the earlier locomtives,
even they all have the same boiler diameter.
It seems to be a modern improved version.
The pistons are 2 inches larger in diameter,
and the steam was superheated,
and I would guess the fire box is bigger, too.
I didn't have time to get a picture of the interior of the cab of the 104, and how much space was inside for the engineer.
That might give me some idea if the original No. 2 was a 'sit-down' locomotive, until they raised the roof.
