@Skeeter1024 posted:FWIW, the book Southern Pacific Ten-Coupled Locomotives by Robert J. Church has a chapter set aside for this one. Some pictures of the boiler construction and of the locomotive at Baldwin.
I believe the book you may be think of is "Three Barrels of Steam", which has two chapters on the Baldwin #60000. Also, it is NOT by Robert J. Church.
Probably not worth while buying the book just for that but if you could get it thru the library. Me, I collect books. Santa Fe Locomotive Development by Larry Brasher also has a couple pages about testing the locomotive. This was the 1st information I had ever encountered about the locomotive.

For what it's worth, there are lots of interesting features about the Baldwin 60000:
1) It is a 3-cylinder compound, with the center cylinder being the high pressure cylinder, while the two outside cylinders are the low pressure.
2) Although a compound, surprisingly all three cylinders are the same bore & stroke.
3) The center cylinder drives the #2, cranked axle, while the two outside cylinders have their main rods connected to the #3 drive axle.
4) The firebox was of the water tube design, which tended to have broken tubes on a fairly regular basis.
5) If it hasn't been mentioned previously, the reason for the strange number of the locomotive was; it was the 60,000th locomotive produced by Baldwin Locomotive Works.
