Key is "a diagram". Yes, NP considered building cab-forward engines and had drawings / diagrams made etc. They even did some test runs with Z-6 5117 (a 2-8-8-4) running backwards pulling a train through tunnels. But none were ever built. (They also considered electrification like GN or Milwaukee did.)
See pg.163 of Frey and Schrenk's book "Northern Pacific Railway: Supersteam Era 1925-1945".
Overmod: >>Sara can tell you about using pulverized coal in place of stoking<<
Ueeeh? can I tell? No, not really. This was my twisted and contorted stage, no real memory of this, only it was a time of agony, never came to nothing-not-at-all. (if this sentence sounds wrong somehow, this is how it should)
From my view now, I can only say: pulverized coal is not suited for loco firing because it produced a lot of burned dust that covers the loco first and then the rest of the line. See the Wendler pulverized coal burners on East-German DR: all sooty and grey-brown. You would have to install complicated secondary appliances to pull the cinder particles out of the combustion gas. But for this you know more about it, Overmod, including things I have not heard of (most of it).

IA and eastern I asked about Northern Pacific cab forwards and got little info.

I wonder if you were referring to the North Pacific Coast cab-forward that may have been the inspiration for the SP cab forwards? This was an experiment by the master mechanic of the line, using a water-tube boiler and oil fired.
NKP guy I am embarassed beyond words to realize now those cab forwards were oil burners. Hand me the dunce cap.
Thanks, Balt.

NKP guy May I ask a sincere, if ignorant, question? Once the cab-forward locomotive, which I always associate with SP, was introduced and (I assume) perfected, why weren't all steam locomotives built this way? This design always seemed to me to make sense even for eastern railroads.

Eastern roads prefered coal - which many had in abundance on their property. Switching to oil would have raised their infrastructure costs.
In today's world of steam locomotives, it is harder to source the proper grade of coal than it is to convert a firebox and tender to oil.
Never too old to have a happy childhood!

Another suggestion is to contact the NPRHS. Also,, Mr. Schenk has an excellent book on Northern Pacific Supersteam.

I don't think this is the first time this question has come up. For example:

Please post a picture of that. I am an NP veteran and have not heard of an NP cab forward. The SP cab forwards all burned oil, but the NP did have a few oil burners.
