That's a water tube boiler? Are there any diagrams of it that can be posted?

As regrettably common, tech morons who don't know the difference have provided wrong information.
The locomotive has a watertube FIREBOX; the boiler (and superheater arrangements) are more-or-less conventional firetube built to operate at the slightly higher pressure (as I recall 350psi nominal, same as for the B&O Emerson watertube boxes) that represents a 'sweet spot' between increased boiler maintenance and more efficient operation of Smith compounding with the provided ratio of HP to LP.
There was a long contemporary evaluation of locomotive 60000 in service that had some discussions of the advantages and disadvantages of the watertube arrangement in service, including the differences when fired with oil vs. solid fuel, and while I don't have time to search this up it is available in full on the Web free. One problem it had 'in spades' was that it was kind of like an installation of Nicholson syphons on steroids with respect to prompt quench of luminous flame and hence gave increased sooting for a given firing level.

Not only does 60000 have a water-tube firebox, it's a three-cylinder locomotive as well. Double whammy.
I remember seeing it at the Franklin Institute, a fun place by the way, and it's impressive as hell, let me tell you.
Unfortunately, what Baldwin was sellin' the railroads weren't buyin'.
