The following information, credit the NPRHA Mainstreeter Magazine Volume 8-1:

The Northern Pacific's first 2-8-0s were the class F's, built in the early
1880's. Unfortunately, although built for the heavy grades in the mountains,
they had too low a factor of adhesion, only 3.85, making them very slippery
and next to useless for their intended service. NP went to Baldwin for a
better mountain loco, and the F-1's were the result, the Hogs had a much
better factor, 4.15 and a tractive effort of 34,500 pounds. They were among
the largest engines in the world at the time. In service, they could
handle 20 loads on a 2.2% grade, a huge improvement over former power.
Throughout their life, they were known system wide as "Hogs", even on train
orders!

They were delivered in 4 groups from 1888-1891 and numbered 470 to 497,
650 to 652 and 10,000. This was Baldwin's 10,000th engine and carried this
number for several years. It later became 460 and finally 55. One was built
as a Vauclain compound, and 2 more were converted in 1896. These proved to
be considerably more efficient in coal and water usage than their simple
sisters, but required more and specialized maintanance. They were simpled in
1903.

As delivered they carried Eames Vacuum brakes on the engine and tender.
These were removed in the late 90's, and standard air brake equipment was
fitted.

Models created in Abacus Train Sim Modeler. These are high in polygon counts: The 60 is 28,476 for the main shape and 4,105 for the parts shape. The tender weighs in at 10,654 polys.


Credits and thank yous:

Steve Thompson for supplying the drawings, photos, data and anecdotes.

Allen Norton for allowing me the use of his 3D driving wheel TSM files, and building excellent steam locos in TSM as a catalyst to get me to try my hand at one.

Jon Davis, Barry (Captain Bazza) Munroe, and Bill Pratt for further incentives towards building steam through much study of their models.

Chris Van Wagoner for his help with the locomotive physics, which made these locos come to life as true mountain hogs.

Jim Bebenroth for testing and positive input.

Herb Kelsey for engine file work, sounds and testing.

Whistle sounds (sou3chime.wav) provided by Chris Signorelli & Bill Hobbs.

There's probably someone else I'm forgetting, please forgive me for it.

Thank you.
