UP 9000 class (also UP-1 through UP-5 class) 4-12-2 prototype info

I’m having a hard time finding length, tractive effort and weight info on these engines. Specifically, I would like to know the overall length, total weight (both with tender included) and tractive effort for the UP-2 class of engines produced in 1926 by the Brooks works with road numbers 9001-9014.

Rated tractive force - 96,650 lbs

Engine wt, 9000-9014 - 495,000 lbs; tender weight 287,000 lbs; total length - 102’-6 5/8"

Later series:

Engine weight 9015-9062 - 496,500 lbs; tender weight 310,500 lbs, total length - 102’- 6 5/8"

Engine Weight 9078-9087, 9500-9514 - 515,000 lbs; tender weight 310,500 lbs, total length 102’- 6 5/8"

These specs are from UP locomotive diagrams. Other sources may vary.

From the UPHS locomotive photo series (9001-9014):

Overall length–various locomotives had either 102’-6-5/8" or 103’-1-5/8" lengths

total weight (loaded)–805,500 lbs when equipped with an 18,000 gallon tender

782,000 lbs when equipped with a 15,000 gallon tender

tractive effort–96,650 lbs

Thanks guys, very much appreciated. I hope I can return the favor some time.

I was curious about the 15000 and 18000 water gal tender you referenced on the 9000’s. Do they have photo’s of both sizes on the 9000’s??

I do not have the 4-12-2 book from the UPHS, but wanted to know if they had good pictures of both types in the book.

Thanks

UPHS produces photo books of various groups of UP locos. They’re up to 21 volumes now with about 80 pages in each one. They’ve done the 4-12-2’s, 0-6-0’s, 4-8-4’s, 2-8-8-0’s, 4-8-2’s, 2-10-2’s, 4-6-0’s, and 4-6-2’s. The photos tend to be 3/4 shots or broadsides. A shot from the rear is quite rare.

Looking at the 4-12-2 photos, I can’t make out much visual difference between the 15k tenders and the 18k tenders–they look a lot alike. I do note that of the pictures I looked at, all the 15k shots were taken in 1927–the 18k shots dated after that. I figure the tenders were replaced with larger ones very shortly after delivery. If you’ve got a 4-12-2, you most likely want the 18k tender, unless you’re modeling 1927. Maybe someone can provide a method of telling one from the other.

I have the UPHS books onthe Mountain and the FEF’s, but did order the 4-12-2’s yet.

My 4-12-2 has the 18000 Gal Tender, but I had never seen any other size tender on the models or my UP books. I have all of the Streamliners from VOL I and will have to do a little reseach on articles about the 4-12-2.
